MESARGus. ;313 



Genus MESARGUS. 

 Mesargus, Melich. Horn. Faun. Ceylun. p. 175 (1903). 



Type, M. asperatus, Melich. 



Distribution. Ceylou. 



" Head with eyes broader than pronotum ; vertex narrow, 

 band-like, in the middle narrowest, at the eyes deeply excavate, 

 anteriorly towards the front " kantig abgesetzt," the front below 

 the border of the vertex concave, on the border of the vertex stand 

 the ocelli which are nearer to each other than to eyes ; face broader 

 than long, front lyre-shaped, above arch-liue margined, antennal 

 cavities very deep, bordered above and on each side by a sharp 

 ridge, cheeks on outer margin rather flatly bayed ; " ziigel " 

 very prominent by sharply deepened sutures, somewhat arched, 

 not enclosed by the cheeks ; clypeus very short, deepened, at the 

 pectus depressed ; rostrum extending to middle coxae ; pronotum 

 seen from the side very strongly arched, at front margins strongly 

 depressed, deeply punctured ; scutellum short, broadly triangular, 

 a broadened transverse line at middle ; tegmina narrowed behind, 

 rounded off at tip, parchment-like, deeply w-rinkled and punctured, 

 veins strong, prominent, outer longitudinal vein forked near base, 

 second longitudinal vein simple, three anteapical and five short 

 apical cells ; legs short, tibiae strongly angulate, rather flattened, 

 widened, posterior tibias without bristles." (Melichar.) 



I have not seen this genus, but from Melichar's description and 

 figure, both of which are here reproduced, it is allied to my genus 

 Moonia {ante, p. 197) which I have placed in the Bythoscopiuae. 

 It differs from Moonia by the structure of the vertex, pronotum 

 and scutelium, but the venation of the tegmina and structure of 

 the head beneath have much in common. It is, however, in the 

 position of the ocelli that we appear to differ as to the location of 

 these genera. The ocelli only being seen in front has been my 

 reason for placing Moonia in the Bythoscopinae, and if that view is 

 sound, Mesargus (which I only know by figure and description) 

 should be placed near it, and not in the Acocephalous Jassinae as 

 advised by MeUchar.

" Tellowish-brown, sti'ongly wrinkled and punctured, eyes 

 somewhat long and oval, large, brown ; face yellowish, strongly 

 punctured, upper part brown as far as the heart-shaped frontal 

 suture ; pronotum deeply punctured, dark brown, sprinkled with 

 numerous small clear white dots, anterior border broad, pale 

 brownish-yellow, on each side near anterior margin a little humped 

 elevation, the very fine whitish middle line on surface of

 deepened transverse line in middle ; tegmina narrowed behind and
