 strong erect spine with a serrate end. (See Tab. LXXXIX fig. 32.)

Uab. Mexico, Coatepec, Paso de San Juan (W. Schaus); Hondukas, San Pedro Sola 

 (Wittkugel, in mus. Staudinger); Panama (mus. Staudinger 1 ). 



Dr. Staudinger has lent us his Honduras specimen, which bears M. Mabille's label, 

 and has doubtless been compared with the type from Panama. It agrees also fairly 

 with the description, in which, however, no mention is made of the two subapical 

 hyaline spots on the primaries. In a male from Mexico only one of these spots is 

 faintly visible, but in the female both are clearly shown. 



We have no specimen for dissection of this species, so that its position must remain 

 for the present uncertain. 



SCANTILLA, gen. nov. 



This genus is very closely allied to Staphylus, so far as the outward appearance goes. 

 Its wings are of the same dull colour, with hardly a trace of any markings. The 

 secondaries are evenly rounded. The primaries have no costal fold, the club of the 

 antennas is stouter, and the terminal joint of the palpi longer and more depressed. 



The following is the only species we can yet place in Scantilla : — 



. 1. Scantilla Opites, sp. n. (Tab. XC. figg. 3, 4, 5 6 .) 



Alis brunneo-fuscis, basi et fascia discali saturatioribus vix variegatis : subtus fere unicoloribus, squamis paucis 

 obscure fulvis aspersis ; palpis subtus albicantibus. 



Ilab. Guatemala, Duefias (Champion). 



Of this species Mr. Champion sent us several specimens. The absence of the costal 

 fold in the primaries of the male distinguishes the species from all the members of 

 Staphylus. 



The male genitalia have a long nearly straight tegumen ; on the dorsal edge of the 

 base of the terminal section stands an erect tuft of hairs: the harpes are short, rounded 

 at the end, which is furnished with short stiff spines ; there is also a row of spines 

 directed upwards from the base of the inner edge of the ventral fold. (See Tab. XC. 

 fig. 5.)
