already described) in one of whicli I can discover no difference 

 in structure between tbe bind legs of tbe male and female, 

 and in another ("certainly H. inornatus, Germ., I tbink) tbe 

 bind femur is more strongly dentate in some males tban in. 

 otbers. All tbe species of this genus tbat I bave seen are sbort, 

 broad insects, witb tbe tborax strongly, or very strongly, 

 transverse, and its basal and apical margins not differing mucli 

 from eacb other in widtb. Tbe following species attributed to 

 DiapJioromerus in Mr, Masters' catalogue belong, I tbink to 

 Sypharpax, viz., (sreus, Dej., ^mcstralis, JDej.,* inornatus, Germ., 

 ^Coxi, Cast, BostocJii, Cast, femoralis, Cast, 7nandihularis, Cast, 

 and perhaps moestus, Dej., and ranula, Cast. Tbe following, 

 which Mr. Masters places in Ilarpalus, also seem from the des- 

 criptions to belong to HypJiarpax, viz., atroviridis, Macleay, and 

 convexiusculus, Macl. 



H. inornatus, Germ. A species occurring commonly at Port 

 Lincoln and also around Adelaide, agrees so well with Germar's 

 description that I have no hesitation in considering it identified. 

 The following particulars are omitted by Germar, and should 

 be placed on record, viz., the male characters are exactly as in 

 typical HypJiarpax (the tooth on the posterior femora, how- 

 ever, being more strongly developed in some specimens than in 

 otbers) the wddth of the thorax is nearly half again the length 

 of the same, and its bind angles are slightly obtuse, but rounded 

 off, tbe hinder part of the lateral margin forming a slightly 

 obtuse angle witb the base, but tbe angle itself being rounded ; 

 the puncture on the third interstice of tbe elytra is nearer to 

 the apex than in some other species of tbe genus. The des- 

 cription of Harpalus australis, Dej., does not altogether agree 

 •with that of II . inornatus (e.g., tbe thorax being called " sub- 

 transversus"), but, nevertheless, it is quite possible they may 

 refer to tbe same species, in which case Dejean's name must 

 bave tbe preference, as in Mr. Masters' catalogue. I should 

 think it also open to much doubt whether Sarpalus Peronij 

 Cast, is not really identical with inornatus. I do not, however, 

 see sufficient reason for Mr. Masters' identification of S. 

 JPeroni with II. novcB-HollandicB, Cast, as their author gives a 

 perfectly satisfactory differential character between them in 

 the shape of the thorax. I possess a Hypharpax from Mel- 

 bourne which I bave little doubt is the latter species. It is 

 extremely close to inornatus, Germ., but has the thorax much 

 narrower in front, and is a little smaller. 



* Mr. Masters treats these three as identical, but I am not clear on the point. 

 Germar's insect may be identical with Dejean's, but Count de Castelnau's 

 description is too vague for identification, and it is very unlikely to be 

 founded on the same insect as Germar's, and if so the description of the 

 colour of the legs must have been founded on a very unusual variety.
