STAPH YLUS. 431 



M. Mabille's kindness, we have seen, and find it agrees with a good series we possess 

 coming from a wide area extending from Southern Mexico to Rio Janeiro. In the 

 colour of the palpi above and of the head and prothorax this species resembles Helias 

 aurocapilla, Staud., but it is a much larger insect, and has the male genitalia differently- 

 formed, as will be seen by comparing the figures. The two insects seem to be strictly 

 congeneric, having similar palpi, and the costal fold of the primaries and the neuration 

 much alike. 



The male genitalia have a ventral hook with two short rounded lobes at the base — 

 one on either side : the harpes are split into two lobes ; the upper one is small and 

 rounded at the end ; the lower one much wider and expanded towards the outer margin, 

 with two rounded angles, the lower one projecting more than the upper. (See 

 Tab. LXXXIX. fig. 6.)

Alis fuliginoso-nigris, squamis paucis ochraceis notatis, fasciis valde indistinctis formantibus : palpis, capite medi- 

 aliter et prothorace supra aurantiacis : subtus alis ut supra ; palpis subtus fusco-albidis, flavido vix tinctis.

A specimen submitted to M. Mabille was returned to us named H. aurocapilla, 

 Staud., with the description of which it no doubt agrees. But we find that Moschler's 

 name A. vulgata is also applicable to it, the type lent us by Dr. Staudinger agreeing 

 with our series from Mexico and Central America. Dr. Staud inger's title has a 

 slight priority. 



Staphylus aurocapilla is readily distinguishable from S. ascalaphus, which it resembles 

 in colour and size, by the orange colour of the upperside of the palpi, head, and 

 prothorax. In this respect it is like S. cupreiceps and S. ceos, but it differs from the 

 former in its smaller size and distinct male genitalia, and from the latter by the colour 

 of the palpi beneath, which are of dusky yellowish white, instead of pure white as in 

 S. ceos, and also in the form of the genitalia. 



The male genitalia have a long single pointed tegumen, with a tuft of hairs arising 

 from the base of the dorsal edge : the harpes are split into two lobes, which overlap at 

 their bases ; the upper lobe ends in a close-set bunch of strong bristles, and at the base, 

 where it overlaps the lower lobe, the lower angle carries a short tooth ; the lower lobe 

 is evenly rounded at the end and covered with long fine hairs. (See Tab. LXXXIX 



fig. ii.)
