STAPHYLUS: 435 



terminating in a rounded lobe, with a mesial ridge extending part of its length, at the 

 base of which, on the dorsal edge, is a fissure overlapped by a rounded lobe projecting 

 backwards. (See Tab. LXXXIX. fig. 23.)

 (B. J.Elwes); Guatemala, San Geronimo, Panima, Chilasco, Duefias (Champion); 

 Panama, Chiriqui (Ribbe, in mus. Staudinger). — Colombia 1 . 



A Chiriqui specimen lent us by Dr. Staudinger, and named by M. Mabille, agrees 

 with the description, having no doubt been compared with the type, which came 

 from Bogota K Our Mexican specimens in every case have three hyaline spots in 

 the apex of the primaries : in some of our Duenas examples the middle spot is absent, 

 as m the Chiriqui insect ; in others from Duenas there are also two, but the lower spot 

 is wanting. We have dissected a Duenas male and one from Omilteme, and find no 

 practical difference between them. 



The male genitalia (extracted from a Duenas specimen agreeing as to its hyaline 

 spots with the Chiriqui male) have a tegumen like that of S. brennus, the harpes 

 are more truncate and slightly serrate at the extremity, the dorsal edge of the terminal 

 lobe has a deep sinus, on the proximal side of which stands a strong erect lobe

11. Staphylus imbras, s P . n. (Tab. LXXXIX. figg. 27, 28 e , 29 $ .) 



Alis saturate brunneo-fuscis, fasciis obscuris vix notatis ; anticis punctis hyalinis subapicalibus nullis ( J ) ; 



palpis subtus ocbraceo-fulvidis, squamis paucis nigris intermixtis. 

 2 mari similis, sed major, fasciis obscuris alarum magis obviis et anticis punctis tribus subapicalibus hyalinis 

 instructis. 



Eab. Mexico, Misantla (F. D. G.), Orizaba (B. J. fflwes), Cordova (//. M?neli), 

 Rinconada, Coatepec, Paso de San Juan ( W. Schaus), Atoyac, Teapa (H. H. Smith) ; 

 Guatemala, Duenas, Zapote, Panima (Champion). 



We have a considerable series of this species agreeing in outward characters, slight 

 though they are. From S. giselus this insect can be distinguished by the absence in 

 the male of subapical hyaline spots, though in the supposed female three are distinctly 

 shown. S. brennus is exceedingly like it, but has rather less prominent terminal joints 

 to the palpi. The following species, S. saletas, is also very similar, but has two sub- 

 apical hyaline spots on the primaries.
