elytra. The only male received is, unfortunately, in a fragmentary condition. The 

 antennae may prove to be differently formed in this sex. 



1. ChaBtodactyla lyciformis. (Tab. XXVII. figg. 27, $ ; 27a, antenna; 

 27 b, maxilla and maxillary palpus.) 



Elongate, moderately convex, flattened above, dull, the elytra slightly shining ; black, the prothorax testaceous 

 or ferruginous, with a broad black median vitta, the scutellum black or ferruginous, the elytra varying in 

 colour from black with the shoulders testaceous or ferruginous to testaceous with a black apical patch ; the 

 antennae black or piceous, with the apical joint and the apex of the tenth testaceous ; the legs black or 

 piceous, the base of the femora and the coxae more or less testaceous ; the upper surface densely, very finely 

 granulate, and thickly pubescent, the pubescence ochreous on the light-coloured portions and fuscous 

 elsewhere ; the under surface somewhat shining, very finely rugulose, and clothed with greyish pubescence. 

 Antennae ( $ ) about two-thirds the length of the body, joint 2 very small, 3 dilated, elongate-triangular, 

 4-10 each acutely produced at their inner apical angle, 4-7 very broadly dilated, 8-10 gradually 

 becoming narrower, 11 slender, as long as 10, and acute at the tip. Prothorax a little broader than long, 

 margined at the sides and in front, the sides rounded and converging almost from the base, the hind 

 angles acute ; the base bisinuate, smooth. Scutellum transversely cordate, with a shallow notch in the 

 centre in front. Elytra elongate, much wider than the prothorax, subparallel to beyond the middle, 

 conjointly rounded at the apex, narrowly margined at the sides, the humeri rounded ; distinctly punctate- 

 striate to the apex, the interstices rather convex. Fifth ventral segment feebly arcuate-emarginate at 

 the apex in the male. 



Length 5g-6|, breadth 2-2J millim. 



Hal. Nicaragua, Chontales (Belt, Janson). 



Five females and one male, all mutilated, the male without head. The elytra vary 

 in colour according to the predominance of the light or dark colour. 



SUPPLEMENT. 



PEIONOSCIRTES (p. 602). 

 2. Prionoscirtes nigripennis. 



Eotundate, convex, shining ; rufo-testaceous, the eyes and elytra black, the apex of the latter narrowly and 

 the antennas and legs testaceous ; finely pubescent, the pubescence fuscous on the dark portion of the 

 elytra and yellowish elsewhere. Head and prothorax sparsely, exceedingly minutely punctate ; antennae 

 about two-thirds the length of the body, the joints from the fourth rather slender and diminishing in 

 length, parallel in their outer half; scutellum and elytra thickly, finely punctate; legs short and stout, 

 the tibiae broad and compressed. 



Length 3, breadth 2 millim. ( $ .) 



Sab. Guatemala, El Keposo (Champion). 



' One female example, in perfect condition. Differs from P. saltitans in its much 

 broader form, more slender antennae (the first joint similarly formed), stouter legs (the 

 tibiee especially), and black elytra, the apical margin only of the latter being pale.
