c? ? . Diftors from hopjf'eri in the following points : 



Forewing pointed, not sinuate between >S(I^ and Sf!'', very shallowly concave 

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

 ai)ex mncli more distinct, whitish scaling at hinder angle more obvious ; red bands 

 of hindwing rather broader, under surface more clayisii. 



S. Tenth tergite more compressed at the tip, less griidualiy rounded in side- 

 view ; sternite much narrower in apical half. (Penis-siieath broken in our only 

 male.) 



Hab. Chiriqui and Honduras ; most likely more widely distribut(>d.

342. Pachygonia ribbei. 



*Parh>i<jonia ribbei Druce, in Bi(jl. C'eiiir. Amei:, 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). 



S ? . Wliereas the four other species of Pachyqonia resemble one another 

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

 scaling of tlie hindtil)ia differs in tiiere 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 ; the reddish bands of the hindwing 

 of siibJiamata, 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 

 abdominal tergites and the clayish postapical patch of the forewing found in 

 the otlier s]>ecies are also marked in ribbei. 



S. Tenth tergite sliorter tiian in the other species, very densely tdotlicd with 

 hairs, compressed, basally elevated in the mesial line, tip rounded, more strongly 

 so than in PI. XLIV. f. 13, sinuate in a frontal view; sternite not much shorter 

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

 Clasper slightly narrowing to the broadly rounded end; harpe (PI. XLVII. f In) 

 dilated at end into an obtuse dorsal and an acute ventral jirocess ; from tiie harpe 

 extends an angle-shaped fold on the clasper, the space limited by this fold clothed 

 with blackisli siiiniform hairs. Penis-sheath (PI. LIII. f. 27) with an obtusely 

 j)ointed, three-edged process, the right-side edge of which is dentate.
