NOTE ON TARSOPHLEBIOPSIS MAYI TILLYARD(ODONATA TARSOPHLEBIIDAE)

:BY LT. COL. F. C. FRASER, I.M.S., RETD.

Bournemouth, England

I wish to correct a serious error made by the late Dr.R. J. Tillyard when describing his Tarsophlebiopsis mayiTillyard. I am indebted to the Curator o2 the SedgwickMuseum, Cambridge University, or the opportunity of re-examining this very interesting ossil wing, an examina-tion which convinces me that we are not dealing with afore wing and a hind wing as Tillyard supposed, but withthe right and left 2ore wings. Tillyard was no doubtswayed by the fact that the impression of the supposedhind wing is pigmented whilst that of the fore wing isnot so; he also based his opinion on what he thought tobe a greater divergence of the origins of Rii (Mi--ii) andIRiii (Ms), a divergence which seems to me to be identicalin the two impressions. His greatest error, however, ishis statement that the ossil shows, unspecialized anteno-dals, which in so archaic a wlng is absolutely impossible.It was to prove this latter point that I requested a loanof the specimen and .ound after my re-examination hatthe two primary antenodals were indeed present. Bymaking .careful s,ketches of the portions of the wing o hesame scale and then making a combined tracing of thetwo, I found that the various longitudinal veins ran insmooth continuation of one another and that lhey wereobviously both portions of a forewing, the left and rightof the insect under examination. Some differences werealso found in the anal area of the wing, where only twocross veins can be seen running between CuA and CuPand only four in the cubital space. The slight reticula-tion in the distal part of this space sho.wn by Tillyardappears to me to be due to foreign matter or artefacts.The primary antenodals are the 3rd and 5th from thebase of the wing. The reticulation posterior to the analvein is of three rows of cells, not a network as shown

by Tillyard. The supposed fragment of "the basal posteriormargin of a hindwing" fits into the area posterior to theanal vein in the right fore wing. After making these cor-rections, I have been able to reconstruct a complete forewing.

IYLANDERIA MYOPS (MANN), NEW COMBINATION (HYMEN-OPTERA: FORMICIDAE).- The small-eyed Cuban Prenolepisof Mann is placed in Nylanderia to follow the modernclassification of these groups. Weber has described a speciestroglodytes, also from Cuba, supposing it to differ frommyops "in distinctly larger size and in the shape of thepeti.ole." Direct comparison of three syntypes of each ofthese forms now in the Museum of Comparative Zoologyshows a slight average size difference, but an absolute over-lap exists .even in this minute sample. Mann’s cited meas-urements are too. low, and could not have been made froma stretched-out specimen. Head and petiole shapes in thesedelicate specimens vary widely, due to warping and buck-ling upon drying out of the alcohol. Weber apparentlyrefers to. such differences, although these are not clearlyseen in the types before me. Formal synonymy follows.Prenolepis myops Mann, 1920, Bull. Amer. Mus. Nat.
