EPITRIX. DEM A.RCHUS.

impression in trout of the basal margin, this impression not being 

 terminated on each side by a longitudinal line; there are long 

 hairs along the lateral margins. Elytra broader at the base than 

 the pronotum. Each elytron has eleven longitudinal rows of 

 deep punctures, the short scutellar row anastomosing with the 

 first at about the middle of the length of the elytron, in such a 

 way as to render it difficult to say whether the first series should 

 not be considered as arising out of ttie so-called scutellar row. 

 All the intervals are raised, and that- between the two outermost 

 rows is broader. Along all the series except the outer marginal 

 one are loug hairs, arising singly, these being longer than those 

 on the underside. The epipleuron of the elytron js indistinctly 

 separated from the upper surface, and it bears a row of punctures 

 along its margin. Underside smooth, shining, sparsely covered 

 with longish white hairs ; presternum more or less broad, with a 

 ridge in the middle, on each of which is a longitudinal depression 

 containing a few little pits; anterior coxal cavities closed behind; 

 mesosternum broader than long and rect angular in shape ; first 

 abdominal sternite very long. All the femora are equally 

 thickened ; tibiae not channelled ; claws appendiculate.

Type in the British Museum. 



Jacoby himself was uncertain about the position of this insect, 

 and he placed it tentatively in Crepidodera. In referring it with 

 some hesitation to Epitrix, I find that the name hirtipennis has 

 been used although it has fallen as a synonym ; I therefore 

 propose lomasa as the specific name. 



Genus DEMARCHUS, Jacoby. 



Demarchus, Jac v Proc. Zool. Soc. Lond. 1887, p. 101. 



Genotype, Demarchus pubipennis, Jac, the only known species. 



Body elongate-ovate, pronotum glabrous, elytra pubescent. 

 Head broad, eyes strongly convex; antennae filiform, the third 

 segment more than double the length of the second; palpi robust. 

 Prothorax transverse, with an anterior and a posterior transverse 

 depression. Scatellum triangular with the apex broadly rotfnded, 

 convex. Elytra with adpressed pubescence, confusedly punctate, 

 finely rugose, their epipleura disappearing behind the middle. 

 Underside : auterior coxal cavities open ; prosternum scarcely 

 visible; mesosternum narrow and pointed; tibiae simple, unarmed; 

 first segment of posterior tarsi not longer than the second ; claws 

 bifid. 



This genus resembles Sebaethe, from which the simple tibiae, 

 transversely impressed thorax and pubescent elytra will at once 

 distinguish it. The posterior femora are moderately but very 

 distinctly incrassate.
