and with a series of long stiff erect setse, the extreme tip very 

 feebly everted. 



T. rbombiis. — Form nearly as in centralis', body shining, black through- 

 out, the four anterior legs and antennse pale testaceous ; hind legs black, ex- 

 cept basal % of the femora, which is rufous; hairs of the upper surface ochreous 

 in color, decumbent, numerous and strongly multifurcate, -with numerous long 

 erect black bristles, a sutural series of white setffi near the apex and a trans- 

 verse sutural white tufted spot before the middle of the elytra; hairs denser 

 and white also on the median line and flanks of the pronotum at base, on the 

 under surface rather dense and white throughout, except near the middle of the 

 abdomen toward base, the last segment bristing with sparse white setae; elytra 

 with feebly impressed series of coarse and deep punctures. Length 2.0 mm. ; 

 width 1.6 mm, 



Arizona. 



The hind femora and tibiae bristle with long stiff and erect black 

 setse and more decumbent whitish hairs ; the femora are some- 

 what swollen beneath near apical third, with about two suberect 

 spiniform teeth ; the tibiae are quite short and strongly sigmoid, 

 being everted toward tip and inverted and narrower toward base ; 

 the last two joints of the tarsi are testaceous. This distinct 

 species is represented before me by a rather large and homoge- 

 neous series. 



The antennal scape in this genus is smaller than in any other 

 type of Rhynchophora known to me, being shorter and narrower 

 than the second joint, to which it is attached axially as in Apion. 

 LeConte has correctly given five small subequal joints following 

 the second, but there is another broader joint properly belong- 

 ing to the funicle and closely adjacent to the club, which was not 

 observed by that author, so that the funicle is 7-jointed, as in 

 Zygopini ; the large curved uncus at the apex of the tibise is 

 also similar to that of the Zygopini.
