684 REVISION OF THE GENL'S PAROPSIS, 



that part in the latter. The expression just quoted is not. I 

 think, incompatible with a place in this subgroup (vide stnnv/, 

 p. 222) and probably indicates the presence of a depression 

 (which is more or less distinctly traceable in most of the examples 

 that T have seen of both the forms I am discussing) on the 

 marginal region of the prothorax on either side, which, however, 

 is of quite different character from the prothoracic foveas of the 

 1st subgroup. In the Sydney specimens the humeral callus tends 

 to be infuscate or black and there is a tendency to the line 

 between the humeral callus and the median transverse row of 

 l)lotches being occupied with a few dark marks, so as to present 

 the appearance described by Dr. Chapuis of the front markings 

 of the elytra being in the form of a semicircle with its extremities 

 on the shoulders. But this difference in markings is most 

 unreliable, and among my specimens from the Sj^dney district are 

 some with scarcely any indication at all of markings on the elytra 

 and one (which I am convinced is but an extreme var. of the 

 same species) with a blackish line running the whole length of 

 tiach elytral series, the suture widely black near the apex and 

 the interstitial dark blotches so curiously coalescing in certain 

 places that it is only on careful consideration one can see them to 

 1)6 mere developments of those forming the typical pattern of 

 suhfasciata rather than notatipennls. 



P. COADNDTA, Chp. 



I have an example of this insect named by Dr. Chapuis. It is 

 structurally very close to P. mbf a sciata, Chp., but is very distinct 

 from all its near allies by the series of punctures on its elytra 

 running in pairs, so that the interstices are alternately wide and 

 narrow. It is of brownish or testaceous colour with the antennae 

 (except near the base) and some blotches on the elytral inter- 

 stices (which, however, are not placed so as to form fasciae) 

 blackish. There is a conspicuous blotch on all the specimens I 

 have seen on either side of the suture at the beginning of the 

 apical declivit}', and in many examples some of the blotches 

 become elongate vittte. The size is about long. 2^ lines; the 

 habitat N.S. Wales.
