466 NEW YORK STATE MUSEUM in the Anophelinae they appear to be absent or else their function is usurped by the largely developed tergum which extends back and protects the smaller organs. These structures are weakly chiti- nized in some species and in others are much stouter and in certain forms are provided with peculiar series of chitinous teeth. This appears quite characteristic of the genus Taeniorhynchus, being particularly well developed in T. brevicellulus Theo. and T. a u r i t e s Theo. The setaceous lobes are pecuUar structures apparently belonging with the preceding organs of the ninth segment, but in reality a part of the rudimentary eighth segment. They are in most Culicinae simple, chitinous lobes bearing a series of stout, chitinous spines. In soi^e instances these latter are very stout. A few Culicinae possess submedian groups of similar chitinous spines on the seventh abdominal segment, as in Culiseta absobrinus Felt. C. consobrinus Walk, and Taeniorhynchus per- turb a n s Walk.
