182 REVISION OF THE GENUS PAROPSIS, 



respect (and in others) it is allied to P. jnctipes, Chp., in which, 

 however, inter alia the sculpture of the whole upper surface is 

 very much coarser. The slight sinuation of the sides of the 

 prothorax in the type is very likely to be merely an aberration of 

 the individual, and is very different from the well marked median 

 sinuation or notch that is so conspicuous in the species that I 

 have associated together, as possessing that character, in the 

 tabulation.

5. Ovata; nitida; fortiter convexa (e latere visa fere ut P. 

 ohsoUta, Marsh., conformata); capite pronoto elytrorumque 

 lateribus rufo-umbratis, elytrorum puncturis nigris; capite 

 sat crebre subtiliter punctulato ; antennis quam corporis 

 dimidium paullo brevioribus; prothorace quam longiori ut 

 5 ad 2 latiori, in disco ut caput (ad latera nullo modo grosse) 

 punctulato, utrinque latera versus profunde foveolato angulis 

 anticis vix mucronatis posticis rotundatis, lateribus parum 

 arcuatis obsolete sinuatis; elytris minus fortiter minus crebre 

 parum sequaliter (fere ut P. ohsoleto',, Marsh., sed magis 

 subtiliter) punctulatis, interstitiis omnino planis. Long. 3^, 

 lat. 2J lines. 

 This is an anomalous species, as its prothorax shows only very 

 slightly the characters that I have regarded as distinctive of 

 Group i., and hence forms a transition to Group ii.; the lateral 

 outline, however, is certainly not evenly arched, though its sinua- 

 tion is very slight and the front angles can scarcely be called 

 mucronate. In P. irrorata^ Chp., the lateral outline of the pro- 

 thorax is very little more sinuate. This species differs from most 

 of the others in the group by its elytra entirely without elevated 

 discal interstices. Among its immediate allies the extreme fine- 

 ness of the discal puncturation of its pronotum is approached 

 only in P. Sospita, Blackb., which differs from it inter alia by the 

 evidently mucronate front angles of its prothorax and by the 

 considerably closer and more evenly spaced discal puncturation 

 of its elytra.
