S ? . Differs from hopffe.ri in the following points : 



Forewing pointed, not sinuate between SC^ and SC'', very shallowly concave 

 between tip and R^, not angled at R-, stigma rather larger, clayish patch below 

 apex much more distinct, whitish scaling at hinder angle more obvious ; red bands 

 of hindwing rather broader, under surface more clayish. 



(J. Tenth tergite more compressed at the tip, less gradually roniulcd in side- 

 view ; sternite much narrower in apical iialf. (Penis-she.ith broken in our only 

 male.) 



Hab. Chiri(iui and Honduras ; most likely more widely distributed.

342. Pachygonia ribbei. 



*Piirhijiioniii ribhi'i Druce, in Biol. Ceiitr. Aiiier., Lep. Het. i. p. 4. n. 3. t. 1. f. 2 (1881) (Chiriqui ; — 

 coll. Staudinger) ; Kirby, Cat. Lep. Het. i. p. 638. n. 3 (1892). 



c? ? . Whereas the four other species of Pachygonia resemble one another 

 closely, the present insect deviates considerably both in structure and colour. The 

 scaling of the hindtibia differs in there being a dorsal and a ventral triangular 

 crest on the first segment, but no crests on the second and third. The distal 

 margins of the wings are more or less denticulate ; the hinder angle of the forewing 

 is less produced than in the other species ; tlie reddish bands of the hindwing 

 of subkamata, etc., are indicated by two short bars at the anal angle. On the 

 forewing below there is a black, curved, discal band. The mesial dots of the 

 al)domi[]al tergites and the dayisli postapical patch of the forewing found in 

 the other s])ecies are also marked in ribbei. 



i. Tenth tergite siiorter than in the other s])ecies, very densely clothed with 

 hairs, coni]>ressed, basally elevated in the mesial line, tip rounded, more strongly 

 so tiian ill PI. XLIV. f. 13, sinuate in a frontal view; sternite not much siiorter 

 than tergite, narrowed in apical fourth, tip rounded, somewhat curved upwards. 

 Clasjier slightly narrowing to the broadly rounded end; harpe (PI. XLVII. f 1(1) 

 dilated at end into an obtuse dorsal and an acute ventral process ; from the harpe 

 extends an angle-shaped fold on the clas|ier, the space limited by this fold clothed 

 wilii Ijhickisli spiniform hairs. Penis-sheath (Pi. Llll. f ','7) with an obtusely 

 pointed, threi'-edged process, the right-side edge of which is dentate. 



Hab. Chiriqui, Panama.
