Lovcjicorn Coleoptera of Cliontales. 221 



niim, anteniifB (except tlie scape), tibiaj and tarsi black. 

 The antennffi (except the shining scape) are densely pubes- 

 cent and the grooves and ridges are faint or scarcely 

 visible ; the third to seventh joints are nnispinose at the 

 apex in both sexes. The thorax is rather tumid on the 

 sides and much constricted towards the base ; the disk is 

 unequal, but scarcely tuberculated, smooth and shining, 

 having only a few scattered punctures ; the flanks are more 

 densely punctured. The elytra are moderately punctured 

 and clothed with short, tawny, erect pile ; besides a number 

 of very long erect hairs. 



I have no doubt the genus Stizocera, Serv., is equivalent 

 to Nephalins as defined by Lacordaire ; but until Serville's 

 type {Sf. (irmata) is re-discovered, it will be unwise to 

 restore his name. 



Alcyopis chalcea, n. sp. Nigra, capite thoraceque 

 nitidis, elytris a?neis splendidis, pedibus flavo-testaceis, 

 geniculis nigris. Long. 10 lin. 



One example. 



This fine Longicom differs from the only other known 

 species, A. cyanoptera (Brazil), by its black head and 

 thorax, and glossy, dark, brassy-green elytra. The scape of 

 the antennfe is rather strongly clavate, brassy-black and 

 shining. The eyes differ from those of A. cyanoptera in 

 the upper lobe being very short and rather broad, Avithout 

 any approach to separation fi'om the lower lobe. The 

 antenniferous tubercles are elevated and pointed. The 

 thorax is elongated, narrowed in front, smooth and glossy, 

 Avith five very prominent wart-like tubercles on the disk. 

 The elytra are very briefly truncated, with obtuse sutural 

 angle and a long acute spine to the exterior angle ; the 

 surface is very minutely and sparsely punctulated, and 

 marked besides Avith three roAvs of much larger punctures, 

 each bearing a stiff bristle ; on each side near the apex is 

 the commencement of a fourth roAV. The legs are long 

 and robust ; the thighs thickly clavate. 



Ileterachthes ohtusus, n. sp. Robustus, dense erecte 

 pubescens, castaneo-fuscus, subnitidus, elytris (apice con- 

 junctim rotundatis) maculis utrimque tribus magnis fulvo- 

 testaceis, 2nda fasciam obliquam formanti ; thorace cylin- 

 drico, sparsim grosse punctato, fuh'O incumbenti-pubes- 

 centi, lined brevi dorsali la?Ai. Long. 7j lin. ?.
