latiin vix seriatim (et pone medium fasciatim) variegatis ; 

 pedibus cinereo-pubescentibus, nio^ro variegatis (prsesertim 

 posticis); sternis ut Z. hifasciatcH conformatis; segmentis 

 ventralibus cinereo-pubescentibus, in medio et utrinque 

 maculatim nudis. Long., 6 1.; lat., 2f 1. 

 This species differs inter alia from those previously described 

 as follows; from metallica, Westw., and pruiyiosa, Boisd., by the 

 presence of transverse impressed lines on the pronotum, from 

 bifasciafa, Pasc, by the presence of basal tubercles on the elytra, 

 from luctuosa, Pasc, and ]:lumifera, Pasc, by the elytral tubercles 

 not being clothed with long soft pale pilosity, from higubris, 

 Pasc, cuneata, Pasc, and Mastersi, Pasc, by the presence of 

 dorsal tubercles on the pronotum, from yentheoides, Pasc, by the 

 emargination of the apex of the elytra, from puniila, Pasc, by 

 the very large and acute lateral tubercles of its prothorax. 

 Z. canosa, Er., is very differently colored, and has very different 

 markings (if I am right in my identification of Z. canosa with a 

 species I collected in Tasmania it differs also in structure, — e.g., 

 the form of the prosternum). I have not seen the description of 

 Z, niveosignata, Jord., but the name would be an impossible one 

 for the present species, which has no white markings on either its 

 upper or under surface. As I am not certain of my identification 

 of some of Pascoe's species being correct I have not mentioned, 

 in distinguishing the present species from them, any of their 

 characters that are not mentioned in their descriptions. I am 

 doubtful as to the sex of the type. I may mention here that 

 valuable specific characters in the Zygocerce (not mentioned by 

 Pasc.) are to be found in the structure of the eyes and of the 

 sterna. 



N.W. Australia ; sent to me by Mr. Masters. 

 Z. hifosciata, Pasc Mr. Masters has sent me a specimen 

 taken in N. Queensland in which the ante-median dark fascia of 

 the elytra is wanting, but which in other respects seems to be 

 identical with Z. bijasciata.
