622 SEBBICORNIA. 



I am unable to find any tangible character by which to separate the Central- 

 American specimens, one of which was found in a mangrove-swamp on the sea-coast 

 and others in the mountains, from the very widely distributed C. variabilis. Compared 

 with European examples they are (with one exception, a female) considerably smaller 

 and less elongate, but agree in other respects. It is advisable, however, to give a 

 description of the Mexican and Guatemalan specimens. No less than six North- 

 American species appear to have been described upon varieties of C. variabilis. 



8. Cyphon guatemalensis. 



Elliptic, moderately convex, shining ; reddish-ochraceous, the eyes black, the antennae and legs entirely testa- 

 ceous; thickly clothed with rather long pallid pubescence. Head moderately broad, very minutely 

 punctate, the eyes large and rounded ; antennae not very slender, rather more than half the length of the 

 body, joints 2 and 3 equal in length, 4-10 moderately long, subequal, 11 much longer than 10. Pro- 

 thorax short and convex, a little rounded at the apex in the middle, the sides converging from the base ; 

 the surface very minutely punctate. Elytra thickly, rather coarsely punctate, without trace of raised 

 lines. 



Length 2i breadth 1| millim. ( <$ $ .) 



Hab. Guatemala, Senahu in Vera Paz, Torola (Champion). 



Two females and one male. This insect closely resembles the European C.pallidulus, 

 Boh. ; but it has differently formed antennae, larger eyes, a smoother head and thorax, 

 and more coarsely punctured elytra. The last-mentioned character separates it from 

 the other Central- American species. The head and thorax are distinctly more sparsely 

 punctured in the male than in the female. The elytral punctuation is uniform in 

 both sexes. 



9. Cyphon ampliceps. 



$ . Elliptic, moderately convex, shining, finely pubescent ; rufo-testaceous or piceous, the antennae and legs 

 testaceous. Head very broad, nearly as wide as the prothorax, very minutely, sparsely punctate, the 

 eyes oval, large, and rather prominent ; antennae long, more than half the length of the body, joint 1 

 exceedingly stout, 2 oval, moderately stout, 3 elongate, slender, longer than 2 or 4, 4-10 decreasing in 

 length, 11 oval, much longer than 10. Prothorax short and convex, a little rounded at the apex in the 

 middle, the sides slightly rounded and converging anteriorly ; the surface sparsely, very minutely punc- 

 tate. Elytra flattened on the disc towards the base, thickly, finely punctate, the punctuation becoming 

 coarser towards the sides and apex, with indications of two very faint raised lines on the disc, the apices 

 conjointly rounded. 



Length 1^-2, breadth l T \j— 1| millim. 



Hab. Guatemala, San Geronimo (Champion); Panama, Volcan de Chiriqui, Pena 

 Blanca (Champion). 



Differs from all the other Central- American species in the unusually broad head 

 (this being very little narrower than the thorax), the large, oval, rather prominent eyes, 

 and the elongate third joint of the antennae. Three specimens : the one from the 

 Volcan de Chiriqui is in a good state of preservation, the others being discoloured and 

 broken.
