Heteromera, irifli xjininnjmical Notes. 55 



This and the preceding species are very closely allied. They 

 hoth have jnirple elytra, Init the colouration in other respects is 

 ditt'ereut ; the punctuation of the elytra in the present species 

 although still sparse is less so than in the preceding species. 

 The head in Z. purpureipannls is broadest across the eyes, and 

 obliquely narrowed behind, whereas in the present species the 

 sides are nearly parallel. The thorax in the former is flattened 

 aljove, suddenly narrowed in front, but in this it is gently 

 convex, and gradually narrowed in front. 



The males of both species have the })enultimate segment of 

 the abdomen deeply triangularly emarginate, and the last segment 

 excavated. 



Zonitis tricolor, Le Gnillou, (IS^If). 



This is a common species which has the elytra aeneous with 

 the base yellow. I am convinced, however, that the Z. O'lieivcri- 

 tris of Redt., (Reis. Novara), is only a variety having the elytra 

 entirely yellow. Both forms are received from Melbourne, 

 Moreton Bay, &c.

Nigrescens, sat nitidus ; capite flavo ; elytrorum basi margini- 

 laisque anguste flavo-piceis. Long. 4|- lin. 



Head triangular, yellow, broadest at the posterior angles, not 

 very thickly punctured, with a, longitudinal impressed line in 

 front. Thorax black, shining, gently convex, narrowed slightly 

 Ijchind, more so in front, as broad as the head, not visibly jjunc- 

 tured, Avith a longitudinal impressed line behind. Scutellum 

 rounded at the apex. Elytra one-third broader than the thorax, 

 parallel, pitchy-black, very thickly and somewhat strongly punc- 

 tured, the extreme base and the lateral margins dirty-yellow. 

 Underside of the body and legs pitchy-black ; claws pitchy.

Note. — I have Just liad occasion to refer to Blanchard's iigure 

 and description of BoHtoplKuinx aiujiUifcr frtun New Zealand. 

 It appears to me to be without doubt the insect described by 

 Fabricius as Dermestes scaher, (tlui type of which is in the P>ritish 

 Museum), an<l known in our catalogues as Pristodi'nis sndicr.
