 X. ( Detnetri'is) tweedensis, Blackb., aud X. ( G ymlndis ) rufescenSy 

 Macl., to both of which it is allied. 



N. Queensland ; sent to rc»e by Mr. Koebele. 



X, {Cymindis) longicollis, Macl. I have received from Mr. 

 Lea some specimens of an insect from Northern N.S Wales 

 which the sender says are C. longicollis, Macl., Mr. Lea appears 

 to have compared them with Macleay's type and therefore 1 

 suppose his deterrrination may be accepted (Macleay's descrip- 

 tion is quite useless). The species sent by Mr. Lea is the same 

 that I have regarded as X. ferruginea, Chaud., and which I still 

 believe to be that insect; if it be so, Chaudoir's name must be 

 dropped in favor of the name Xanthophoea longicollis, Macl. 



X. {Demetrias) rufescens^ Macl. I have examples from Cairns 

 (Macleay's locality) of an insect which agrees well with the 

 description of this species except in its elytral interstices (not 

 "without punctures" but) under a strong lens showing some fine 

 and very sparse puncturation. I have no doubt of its being 

 X. rufescens but I am not satisfied that it is distinct from 

 X. longicollis. Its elytral interstices are certainly less strongly 

 convex (especially near the lateral margins) than those of 

 longicollis, but I cannot find other characters to distinguish it. 



TRIGONOTHOPS. 



In Proc. L.S., N.S.W., 1892, pp. G5 and 66, I furnished some 

 notes in which I drew attention to the difficulty of distinguishing 

 T. longiplaga, Chaud, from T. paciflca, Er. Since the publication 

 of those notes I have collected both species in the localities where 

 the types were taken, and have found that they are certainly dis- 

 tinguishable by their sexual characters, but I cannot distinguish 

 them otherwise. The male of the species which I take to be 

 longiplaga has its front <-arsi strongly dilated and four setigerous 

 punctures on its apical v^entral segment ; the male of pacifica has 

 front tarsi much less dilated, and only two setigerous punctures 

 on its apical ventral segment. Usually the anterior pale spot 

 reaches the front margin of the elytra \n longiplaga ; it very 

 rarely does so in pncifica but there are exceptions in both species. 

 The "vars. ?" lindensi>i and occidentaUs which [ referred to 

 pacifica may possibly be vars. of Lmgiplaga. — or even distinct 

 species, — as they are females, and I cannot find any character to 

 differentiate the females. I have not seen a male of pacifira 

 except from Tasmania or of longiplaga except from Victoria. 



T. Jl'ivofasciata, Chaud. This species is distinguishable from 

 T. pacijicn, Er., and longiplag'i, Chaud, by its wider prothorax and 

 its elytral interstices considerably more distinctly punctured. 

 The lateral dilatation of the anterior pale space on its elytra is
