8. Mogoplistes OCCidentalis. Nearly uniform chestnut-brown, 

 slightly bauued with brownish t'u^cous. It differs conspicuously from 

 the European species, by its much greater size and the proportionally 

 greater length of the ovipositor; my specimens are imperlect and are 

 almost entirely deprived of scales. Length of the body .42 in.; of the 

 ovipositor, .32 in. Mr. Uhler sent me two $ from Cape St. Lucas, 

 Lower California. 



Cycloptilum nov. gen. 



Allied to Oniehius. Head very small, well and evenly rounded, pro- 

 duced anteriorly; eyes of medium size, subpyriform , the larger end 

 directed upward, but little prominent; antennjE very long and slender, 

 distant at their insertion, the basal joint large, the remaining joints 

 nearly equal; labrum bifid; maxillary and labial palpi ajiparently sim- 

 ilar, the terminal joints a little enlarged and obliquely truncated at the 

 tip. Prothorax very large, nearly as long as the abdomen, greatly 

 broadened and produced posteriorly, the posterior border well rounded, 

 forming nearly a semicircle; pleura shallow and incurved, posteriorly 

 wanting; tegmina almost entirely concealed by the expansion of the 

 pronotum, but with the dorsal field as broad as the pronotum in its 

 widest part, the tips well rounded, like the prothorax, and covering 

 half of the abdomen; the lateral field is also well developed, em- 

 bracing the abdomen; wings nearly or quite abortive in the single 

 species known to me; legs short, simple; hind femora greatly dilated; 

 hind tibias and first joint of tarsi furnished with apical spines. Ab- 

 domen depressed, nearly equally broad throughout, slightly tapering 

 at the extremity; anal ccrci tapering, more than half as long as the 

 abdomen; whole body, in the single species known to me, covered 

 with scales. 



9. Cycloptilum squamosum. Head and prothorax yellowish- 

 brown; a dark brown or blackish band behind the eyes, extending to 

 the anterior part of the pronotum, with a scarcely perceptible median 

 carina; pleura of the pronotum covered with whitish scales; tegmina 

 extending three one-hundredths of an inch beyond the prothorax, 

 pellucid, with a few pinkish veins on posterior border; legs pale yel- 

 lowish, covered with brownish scales, least conspicuous on the hind 

 femora; basal half of abdomen covered with whitish scales, apical 

 half with blackish ones'; anal cerci whitish, a few long and distant 

 hairs on the pleura of the pronotum, the femora and the anal cerci. 

 Length of body .25 in.; of pronotum .13 in,; of hind femora .14 in.; 

 of antennae .5 in.; of anal cerci .1 inch. One 3, Texas, BeltVage.
