apex, the teiminal one shallowly emarginate. Posterior tibiae 

 straight. 



Length 4^ mm. 



Hab. Guatemala, San Geionimo. 



Two specimens, assumed to be males, left by Gorliam 

 under M. laticeps, but differing from that insect in the 

 less widened, subopaque head, the much smaller eyes, and 

 the more slender, less elongate antennae (formed much as 

 in the male of M. brevipennis, Gorh.), with dark basal 

 joint. The elytra are a little longer, and the prothorax 

 narrower, than in M. brevipennis.

 iii, 2, p. 104. 



Hab. Guatemala, near the city and Duenas. 



The specimens of this species before me apparently 

 include both sexes. It has much smaller eyes than M. 

 laticeps, the head pale in front and at the sides behind, the 

 elytra shorter, etc. 



6. Malthinus terminalis. 



Malthinus terminalis, Gorh., Biol. Centr.-Am., Coleopt. iii, 

 2, pp. 103, 309. 



Hab. Panama, Chiriqui. 



Found in plenty in Chiriqui. The comparatively stout, 

 pubescent antennae (which have the apical one or two 

 joints yellow), the short prothorax, the very short, wholly 

 infuscate, vaguely punctulate elytra, etc., give this insect a 

 different facies from the typical species of the genus. The 

 mandibles are toothed within. The peculiar genital 

 armature of the male is j&gured on Plate VII, fig. 48. 



7. Malthinus diversicornis, n. sp. 



Malthodes pallipes, Gorh., Biol. Centr.-Am., Coleopt. iii, 2, 

 p. 310 {nee p. 105) (part.). 



Opaque, the elytra slightly shining ; piceous, the front of the head, 

 the mandibles, and legs testaceous or obscure testaceous, the last 

 two joints of the antennae pale yellow; head and prothorax alu- 

 taceous, minutely punctate, the elytra vaguely punctulate. Head 

 broad, transversely convex, comparatively short, obliquely narrowed 

 behind the eyes in (^, the eyes moderately large ; mandibles sharply
