This is the only species in which I am acquainted with 

 both sexes. The clothing and tubercles are different to those 

 of nasuta and caligata, and the pectoral canal is shorter ; 

 the most readily seen difference, however, is the absence of a 

 sutural depression. The type male and female have been 

 returned to Mr. Simson, a second female being retained by 

 myself. 



Tetengia, n. g. 



Head rather large, partially concealed. Eyes ovate, not 

 very widely separated, coarsely faceted. Rostrum rather short 

 and stout, feebly curved. Antennae stout, scape shorter than 

 funicle, inserted nearer base than apex; two basal joints of 

 funicle elongate, the others transverse and increasing in width ; 

 club stout, continuous with funicle. Prothorax widely trans- 

 verse, base truncate, sides at base excavated to receive femora, 

 constriction absent; ocular lobes very obtuse. Scutellum ab- 

 sent. Elytra closely applied to, with the outline continuous 

 with, that of prothorax. Pectoral canal deep and wide, ter- 

 minated between intermediate coxae. Mesosternal receptacle 

 very feebly raised in front and depressed at the sides, walls 

 equal throughout, emargination semicircular; cavernous. 

 Metasternum much shorter than the following segment; epis- 

 terna rather narrow but distinct throughout. Abdomen 

 moderately large ; first segment as long as the three fol- 

 lowing combined, second depressed below first, its sutures 

 straight, third and fourth combined distinctly longer than 

 second or fifth, their sutures deep and wide. Legs 

 short and stout ; femora deeply grooved to receive tibiae, 

 edentate, posterior terminated before apex of abdomen; tibiae 

 very wide, outer edge strongly rounded and thin, inwardly 

 excavated to receive tarsi ; tarsi rather short and stout, third 

 joint not much wider than second and not bilobed to base, 

 fourth long and very thin ; claws feeble. Briefly ovate, feebly 

 convex, nontuberculate, apterous. 



The shape of the prothorax, abdomen, and legs render 

 this a highly remarkable genus; its true position I am very 

 doubtful of, but it appears to approach Tentegia. 



Tetengia solenopa, n. sp. 



Blackish-brown or dark-brown; prothorax pale, antennae 

 red. Prothorax moderately-densely clothed with ochreous 

 scales, with a few white ones in small spots ; elytra with whitish 

 scales, not very densely distributed, and frequently condensed 

 into small spots, second interstice at apex with similar scales 

 to those on prothorax.
