C.fumatus. A pair of C. sallei as here identified was presented to the 

 Museum in 1897. The types were also from Venezuela. 



G. fumatus Fairm. — Three males and three somewhat abraded 

 females, all from Venezuela. A very close ally of C. humeralis, the $ , 

 according to Fairmaire, wanting the large tuft of long black hairs on 

 the elytra, and the S having the sutui-e moi"e strongly gibbous at the 

 middle. The $ 5 before me have the elytra cyaneous, with a common, 

 broad, post-scutellar patch, a lateral stripe, and one or two subapical 

 spots (connected along the suture with the scutellar patch in one 

 example), testaceous. Two varieties of C. fumatus, from Colombia, 

 have been named by Pic luteonotatus and wheeleri (L'Echange, 1913, 

 p. 108), both apparently from $ $ , though wheeleri is said to be cT . 

 The types, <S $ , were found by Salle on potato plants at Merida, 

 Venezuela. Fairmaire suggests that these insects may be attached to 

 wild SolanacejB. 



C. ohesus Fairm. — Seven males and nine females, showing no varia- 

 tion, the (S liaving remarkably inflated opaque elj^tra. — Venezuela. 



G. lugubris Fairm. — One male and three females, the latter having 

 the elytra more dilated at the apex than stated in the description of that 

 sex. — Colombia and Venezuela. 



G. abnormis Fairm. {correptus Champ.). — The S of this species 

 was described by Fairmaire (Rev. et Mag. Zool. 1878, p. 268), the $ by 

 Pic (L'Echange, 1913, p. 109), and both sexes by myself in a recently 

 published paper on Asfulus *, under which the insect was placed with 

 some doubt, the c? having the elytra very little wider than the $ . The 

 elongate and narrow J tegmen, as stated in the description of A. cor- 

 reptus (No. 28), is different from that of all the numerous species of 

 Astylus enmnerated in the above-mentioned paper, and, in fact, is ver}^ 

 like the con-esponding organ of G. sallei, in which it is dilated at the 

 tip, and closely ciliate at the sides before the apex. In addition to the 

 abraded pair recorded by myself, the Museum possesses another pair from 

 Venezuela {ex coll. Fry) in much better condition, with the luteous 

 pubescence of the upper surface intact, and the intermixed long, erect, 

 darker bail's standing out very prominently on the prothorax and 

 elytral humeri.
