HABKOPHOKA. 



Habrophora, Erichson, Arch. f. Naturg. 1847, p. 163. 



Three species, from Peru and Colombia respectively, have up to the present time been 

 described as belonging to this genus, which is distinguished by small, finely pubescent, 

 and rather delicate forms, having somewhat the appearance of species belonging to 

 the Galerucidse. The deeply emarginate eyes is the principal character of Habrophora, 

 of which one species has been received from Central America : — 



l. Habrophora maculipennis* 



Subelongate, fulvous below ; joints seventh, eighth, and. the two terminal ones of the antennae piceous ; above 

 obseure fulvous, finely pubescent ; elytra with longitudinal and transverse fuscous markings, more or less 

 distinct. 



Length lf-2 lines. 



Head extremely finely pubescent, not visibly punctured ; clypeus not separated from the face ; antennas slender 

 and filiform, o£ more than half the length of the body ; thorax pubescent like the head, its posterior 

 margin sinuate at each side, obscure fulvous or fuscous, or the sides of the latter colour only ; elytra sub- 

 parallel in the male, more convex and slightly widened in the female, covered with yellowish-grey fine 

 hairs, very finely punctate-striate, the interstices partly denuded of hair, and in the shape of fuscous 

 lines of which about six extend from the base to the middle of each elytron, behind which a transverse 

 zigzag band is placed ; three other broader longitudinal bands are situated towards the apex ; legs and 

 underside light fulvous, also finely pubescent. 



Hab. British Honduras, river Hondo (Blancaneaux) ; Guatemala, Cubilguitz, EI 



Keposo, San Isidro (Champion); Nicaragua, Chontales (Janson); Panama, Volcan de 



Chiriqui (Champion). 



Of this species about twenty specimens have been obtained, which vary much in size, 

 and also in coloration, the elytral markings being sometimes almost entirely obsolete ; 

 the antenna?, too, are either entirely testaceous or have the seventh, eighth, and apical 

 joints piceous. H. varia, Erichs., seems to be a closely-allied form, but is described as 

 being black below, and differing in the markings of the elytra, as well as in the colour 

 of its legs.

Up to the present time no species belonging to this genus have been described 

 from Central America, the only " habitat " recorded being North America and Cuba. 

 The genus is distinguished rather easily by the emargination or notch of the four 

 hinder tibiee in connexion with the bifid claws ; the concave anterior thoracic episternum 

 preventing them being confounded with the Typophorinse, which agree in the former 

 characters. Chapuis has united this genus with Myparida of Baly, which certainly 

 bears a great resemblance to it ; but this latter genus (as Mr. Baly has pointed out) has 

 the second joint of the antenna? always much shorter than the third one, while in
