PSEUDOEPITEIX. 341 



acute obliquely cut posterior margin of the thorax at the angles, which is much more 

 decided and marked than in the genus Disonycha. Numerous specimens were obtained 

 in Chiriqui, a single one only from Mexico, and a few from Guatemala, thus proving the 

 rather wide distribution of the species. 



PSEUDOEPITEIX. 



Body narrowly elongate, parallel ; antennae filiform, the third joint slightly longer than the second, terminal 

 joints slightly thickened ; thorax quadrate, the sides straight, the surface obsoletely and transversely 

 grooved near the base ; elytra punctate-striate ; posterior femora moderately thickened ; tibiae simple, the 

 posterior ones with a minute spine ; the first joint of the posterior tarsi as long as the two following joints 

 united ; prosternum very narrow ; anterior coxal cavities closed ; claws appendiculate. 



The general appearance of the little species for which I propose the present genus is 

 not unlike that of a small Donatio, or Lema, on account of the square-shaped thorax, 

 the sides of which are perfectly straight or even a little concave : the same shaped 

 thorax is to be found in Sangaria, Harold. In this genus the posterior margin of the 

 thorax is oblique at the sides, and the metatarsus of the hind tibiae is as long as the 

 three following joints united. In the present genus the thoracic groove is obsolete, 

 and not limited laterally by another longitudinal groove. With Crepidodera the 

 present genus cannot be confounded, as in that genus the thorax is always more 

 transverse and the sides rounded, the surface also more convex and very little wider at 

 the base than the elytra ; the same remark applies to the genus Epitrix. 



1. Pseudoepitrix hirtipennis. (Tab. XX. fig. 22.) 



Pale testaceous ; apical joints of the antennae, the breast, and part of the abdomen piceous ; thorax rugose- 

 punctate ; elytra punctate-striate, with rows of single hairs, the suture and a small spot near the base 

 obscure fuscous. 



Length 1 line. 



Head with an obsolete depression round the inner margin of the eyes, impunctate, the vertex with an obscure 

 piceous spot, the frontal tubercles short but distinct ; antennae more than two thirds the length of the 

 body, the lower joints testaceous and stained with piceous above, the others black ; thorax very little 

 broader than long, the sides straight or slightly concave, the basal sulcation obsolete and indistinct at the 

 sides, another still more obscure depression is placed close to the anterior margin, the surface closely and 

 somewhat rugose-punctate ; elytra distinctly wider at the base than the thorax, with regular rows of 

 closely approached and distinct punctures, which are more finely impressed near the apex ; the interstices 

 between the punctures are beset with rows of single whitish hairs ; the suture is narrowly fuscous, and a 

 small obscure spot of the same colour is placed immediately behind the base ; legs and the last two or 

 three abdominal segments entirely pale testaceous ; rest of the underside and the claws piceous or black. 



Hab. Panama, Volcan de Chiriqui (Champion). 



The general colour of the upper surface of this species is a pale testaceous, the thorax 

 being sometimes almost whitish ; in some specimens there is another very obscure spot 

 placed below the middle of each elytron ; the posterior femora are moderately incrassate. 

 P. hirtipennis seems not to be uncommon in Chiriqui, to judge by the numbers obtained.
