Kirby's original descrij)tion is made from the dark form of 

 this insect, in which the femora and tibiai are black in the 

 middle, and the elytra have a fm'cate black streak on each 

 side. The type of White's sericinus is a specimen of this 

 form. 



6. Acyphoderes Olivierij Bates. 



Acyphoderes Olwieri, Bates, Trans. Ent. Soc. 1870, p. 328. 

 Necydalis abdotmnalis, Oliv. no. 74, p. 8, pi. 1, f. 5 (?). 



Amazons and Cayenne. 



Olivier makes no mention of golden pubescence in his de- 

 scription ; and the elytra in the figure have not the form of 

 those of the present species. Nevertheless it is probable his 

 species is the same as A. Olivieri. 



7. AcyjyJioderes carinicoUiSj n. sp. 



A. minor, fusco-niger, minus pubeseens, femoribus IsDte rufis, 

 posticis basi flavo-testaceis ; thorace anguste oblougo-ovato, line- 

 atim aureo-tomentoso, carina la;vi mediana marginem anticum 

 attingente, altera utrinque latiore grosse punctata. Long. 6 lin. $ . 



Prov. Rio Janeiro {coll. Dr. Baden and H. W. Bates) . 



Small and slender for this genus. Head punctate-scabrous, 

 partly golden tomentose ; muzzie moderate ; eyes (female) not 

 widely distant in front. Antennae elongate, slightly thickened 

 towards apex ; joints moderately dilated at apex, and serrate 

 from the fifth. Thorax oblong-ovate, as in Bromiades hra- 

 chyptera, sparsely hirsute, and appearing glabrous, except the 

 lines of golden tomentum, of which there are two dorsal (one 

 on each side the median line), one along the anterior and 

 posterior margin, and a short oblique one trending towards the 

 disk from the tomentose flanks. The three longitudinal ribs 

 of the disk are coarsely punctate, except the anterior part of 

 the middle one, which is smooth and extends to the fore mar- 

 gin. Scutcllum golden tomentose. Elytra elongate, subulate; 

 margins deep black and clearly defined, and on each side emit- 

 ting a branch, which passes above the humeral angle to the 

 base ; rest of surface yellow, vitreous. Body beneath pitchy 

 black; breast golden tomentose. Legs black; thighs red; 

 posterior pair at base pale, sometimes with a dusky ring at 

 commencement of the rather abrupt club.
