352 PHYTOPHAGA. 



to separate it for the following reasons : — There is no trace of an elytral basal elevation 

 in E. intermedia, the thorax is not finely but strongly punctured, and the elytral inter- 

 stices are not flat but raised. Amongst the black species the present one is the largest, 

 with the exception of E. fuscula, which is larger still ; the thoracic groove is nearly 

 straight and deep, and the space behind it is as strongly punctured as the rest of 

 the thorax. 



15. Epitrix dilaticornis. (Tab. XXI. fig. 4.) 



Dark fulvous ; antennae with dilated intermediate joints, the latter black ; thorax finely punctured ; elytra 

 finely punctate-striate, the base strongly raised, covered with yellow hairs. 



Length 1 line. 



Head impunctate ; frontal tubercles in the shape of narrow, oblique ridges, bounded above by a narrow groove 

 round the inner margin of the eyes ; antennae more than half the length of the body, the fourth to the 

 seventh joint gradually but strongly dilated, covered with coarse and long pubescence, the four basal and 

 the two terminal joints fulvous, the rest black ; thorax transversely convex, the basilar groove straight 

 and deep, the surface finely and not very closely punctured ; elytra much wider at the base than the 

 thorax, the basal portion strongly raised, moderately strongly punctate-striate, the interstices rather 

 closely covered with long yellow pubescence.

This species, distinguished by the dilated intermediate joints of the antenna?, is very 

 closely allied to E. apicicornis, Baly, which it resembles in colour, and of which I have 

 the type for comparison ; the latter, however, has the head differently formed, as 

 there is a rather broad space in front of the eyes (called by Baly the interocular space), 

 which in the present species is wanting ; the dilated antennae, which is another character 

 peculiar to E. dilaticornis, and the much more strongly raised base of the elytra will 

 further distinguish this species from that of Mr. Baly ; in the female the antennae are 

 much less dilated and almost normal, but the base of the elytra is strongly raised. 

 Chorodecta, a genus described by Von Harold, has also dilated antennae, and seems 

 almost identical in every other respect with the species here described; but in 

 Von Harold's genus the anterior coxal cavities are described as open and the pro- 

 sternum as exceedingly narrow, characters which do not apply to E. dilaticornis. 



16. Epitrix fiilvifrons. 



Ovate, convex, black ; head obscure dark fulvous ; antennae, knees, and tibiae fulvous ; thorax strongly punc- 

 tured ; elytra deeply punctate-striate, the base strongly raised. 



Length 1 line. 



Head impunctate, inner margin of the eyes with a few deep punctures, frontal tubercles narrow and transverse, 

 carina acutely raised ; antennae nearly as long as the body, the terminal joints distinctly thickened ; 

 thorax transverse, the sides not much deflexed anteriorly, sides nearly straight, basilar groove very 

 shallow in the middle, more distinctly marked at the sides, surface rather closely and strongly punc- 

 tured ; elytra regularly punctate-striate to the apex, the base distinctly raised.
