REPORT OF THE STATE ENTOMOLOGIST I904 493 



Female. Lobes about four times as long as broad, somewhat 

 contracted at the base and tapering rapidly from the basal third 

 to the rather acute, almost unarmed tips. Ventral plate not as 

 wide as a lobe and extending to the posterior half, strongly emargin- 

 ate apically. Posterior margin of eighth segment armed with a 

 series of long, stout spines. 



Uranotaenia sapphirina O. S. Genitalia, male. Basal clasp 

 segment stout, subconical. Terminal clasp segment stout, nearly 

 straight and tapering rapidly near the tip to a nonarticulate spine. 

 Interior face of apical portion denticulate and with a small spine. 

 Claspette probably represented by a slight setaceous process near 

 the middle of the basal segment. Harpes slender, slightly con- 

 stricted at the apical fourth and with a dark brown, slightly curved 

 and enlarged apex. Harpagones stout, constricted just beyond the 

 middle and ending in a pair of divergent blunt processes. Unci 

 stout, approximate with a number of diverging apical chitinous 

 processes. 



Uranotaenia socialis Theo. Genitalia, male. Basal clasp seg- 

 ment very broad with the apex broadly roimded. Terminal clasp 

 segment stout, nearly straight and tapering rapidly near the tip 

 to a moderate, acute apical spine. Claspette probably represented 

 by a slight setaceous process near the middle of the basal segment. 

 Harpes stout, broad, apparently with three stout subapical teeth 

 on each side, apex blunt. Harpagones stout, tapering and bearing 

 one stout subapical and two apical curved, chitinous processes. 

 Unci slender, approximate, broadly rounded posteriorly. 



The parts are so minute and the material so scanty that it was 

 impossible to make a preparation showing all the details in a satis- 

 factory manner and it may be necessary to revise the above with 

 more material at hand. 



Wyeomyia smithii Coq. Genitalia, male. Basal clasp segment 

 rather stout, curving gradually to a broadly rounded apex, and 

 with a small basal, setaceous lobe, the claspette. This segment is 

 amique since its distal portion is composed of two equal lobes very 

 slightly connected posteriorly. Terminal segment remarkable, 

 composed of an irregular main limb terminated by several con- 

 spicuous teeth and ornamented along its inner margin with a series 

 of rather stout spines. Near the middle arises a fingerlike process 

 thickly armed with a brush composed of oblique fine retrose 

 spines. On the opposite side of the central limb there is a large 

 falcate process, the inner surface armed with several stout spines. 

 This arm is connected with the central limb by a broad sheet of 

 probably chitinous tissue forming a sort of pocket. Harpagones, 

 much smaller than the harpes, both consisting of a broad basal 

 platelike structure rotmding abruptly to a short, stout, bladelike 

 segment armed with a conspicuous spine, and with its apex obliquely 

 truncate. Unci broad, platelike, fused mesally to form a keel-like 

 structure. Setaceous lobes rather small, each bearing four or five 

 long, stout setae. 



Female. Lobes broadly roimded, apparently attached dorsally, 

 the nearly circular ventral margin free. Tergum broadly rounded
