of New Phytophaga. 613 



silvery hairs. Thorax equal in length to the breadth, narrowed in 

 front, sides constricted in the nniddle, upper surface impressed with 

 a large but shallow fovea near the basal margin ; disc subre- 

 motely impressed with large^ somewhat deep punctures. Scutellum 

 glabrous, subelongate-trigonate, its apex rounded. Elytra much 

 broader than the thorax, sides parallel, subcylindrical, basilar 

 portion obsoletely raised, bounded beneath by an indistinct and 

 ill-defined transverse depression ; surface deeply and regularly 

 punctate-striate, punctures round, piceous, interspaces smooth, 

 plane in front, costate below their middle. Abdomen smooth, 

 nitidous ; just within the posterior margin of each segment is a 

 narrow row of fine punctures, clothed with very fine silky hairs, 

 remainder of their surface (with the exception of a few scattered 

 hairs) glabrous, impunctate. 



The red colouring on the under surface of the body varies in 

 degree in different individuals from the typical state up to variety 

 A., and possibly in some specimens the legs themselves are more 

 or less rufous. 



2. Crioceris later itia. 



Elongata, subcylindrica, rufo-fulva, nitida ; antennis, epimeris, 

 pedibusque (femoribus infra exceptis) nigris ; abdomine im- 

 maculato ; mesosterno apice dilatato, retrorsum curvato. 



Long. 4 — 5 lin. 



Northern China. Collected by Mr. Fortune. 



This insect is so closely allied to C siibpolita, Motsch., from 

 Japan (also found in Northern China), that for a long time I had 

 the two species intermingled in my collection ; the form of the 

 mesosternum however is a good distinctive character between the 

 two ; this part in C. subpoida is of normal size and form, viz., 

 oblong, and nearly erect, its apex being truncate and not curving 

 backwards. The abdomen in the present species wants the black 

 spots present in C. subpollta ; in all other respects the insects 

 appear to be almost indentical. 



3. Crioceris Clarhii. 

 Oblongo-elongata, subcylindrica, nigra, nitida ; femoribus an- 



ticis quatuor medio, posticis infra, thorace elytrorumque 

 limbo (hoc basi et apice late dilatato) rufo-fulvis ; elytiis 

 punctato-striatis, striis apice saepe deletis. 



Var. A. — Thorace nigro, abdominis disco rufo-piceo. 



Long. 4 lip.
