CAKKHENES. 389 



The genus has several allied species, which may be separated into two groups by the 

 structure of the male organs, the particulars of which are given below. Nearly all 

 the species occur in Mexico or Central America, and some of them have a wide range 

 over the Southern Continent.

Alia fuscis, maculis obscurioribus notatis ; anticis punetis septem semihyalinis — una cellulari, tribus subapi- 

 calibus et tribus discalibus ; posticis f asciis maculosis tribus notatis — una distincta submarginali, una irre- 

 gulari discali, tertia indistincta per cellulam : subtus isabellino-fuscescentibus, maculis obscurioribus et 

 punetis semihyalinis ut supra sitis, illis minoribus, macula ad angulum analem nigra ; palpis subtus albis.

 dinger), San Pedro (G. M. Whitely). 



Dr. Staudinger has lent us a specimen from Honduras named L. fuscescens by 

 M. Mabille, and with this insect a series long in our possession agrees. The range of 

 the species extends from Southern Mexico to Honduras, but appears to be nowhere 



common. 



C. fuscescens is the darkest and most uniformly coloured of this section of the genus, 

 and on the upper surface of the wings it resembles C. meridensis ; beneath, however, 

 the glaucous area on the secondaries of the latter species at once distinguishes it. 

 The male organs are very different : these in C. fuscescens have a truncate tegumen, 

 which is cleft in the middle, and has at each outer corner a short hook and a short 

 spine on either side near the base ; the harpes end in two lobes, the points of which 

 approach each other, and are shaped rather like the claw of a lobster, another lobe 

 directed forwards lies on the inner surface. (See Tab. LXXXV. fig. 21.) 



2. Carrhenes calidius, sp. n. (Tab. LXXXV. figg. 22, 23 e .) 



C. fuscescenti similis, sed anticis ad medium marginis interni et posticis area discali omnino albicantioribus, 

 harum fascia maculosa discali magis obvia : subtus posticis albicantibus, maculis omnibus evanascentibus, 

 macula nigra ad angulum analem nonnunquam absente. 



Eab. Mexico, Atoyac (H. H. Smith, Schumann) ; Guatemala, Zapote, Panima 

 {Champion); Nicaeagua, Chontales {Belt) ; Costa Rica, Irazu {Bogers); Panama, 

 Bugaba (Champion), Chiriqui (Bibbe, mus. Staudinger).— Amazons Valley. 



Though resembling C. fuscescens in the form of the male organs, and therefore 

 evidently closely related to that species, C. calidius may readily be distinguished by the 

 much paler colour of the central portion of both wings ; it thus resembles C. canescens,
