OF NEW ZEALAND. 985 



Long., IS^mm. 



The salient characters of this species have been mentioned by 

 Mr. Bates as above. 



The thorax is very broad, the length, however, being more than 

 three-fourths of the width, without sculpture, with the lateral 

 margin rather broadly and evenly reflexed from base to ape^y the 

 base a little narrower than the front, the hind angles unusually 

 obtuse. The elytra are very broad, rather short, very deeply and 

 evenly striate, with a single puncture placed near the extremity of 

 the second interstice. The grooving of the tarsi is variable in its 

 development ; it may be, and usually is, nearly entirely absent, but 

 in other examples there is a distinct groove on each side of the middle 

 of the basal joints, extending sometimes as far as the fourth. The 

 male has three, the female five, setigerous punctures on each side of 

 the hind margin of the last ventral segment. It is allied by the 

 single puncture on the second interstice to Colpodes neo-zealandicus, 

 Chaud. Whether this latter species be G. novce-zealandicz, Fairm., 

 or not I cannot say ; Fairmaire's species is not alluded to by 

 Chaudoir. 



It may here be useful to state, for the information of New Zealand 

 naturalists, that in the Annales de la Societe Entomologique de 

 France, 1878, Chaudoir has described five species from New Zea- 

 land purporting to be new viz., Colpodes neo-zealandicus, p. 294 ; 

 bidens, p. 303 ; crenatus, p. 304 ; cardiophorus, p. 305 ; macropterus, 

 p. 370. These are not alluded to by Broun, so that it is probable 

 that some of his numerous species may be synonymous with those 

 of Chaudoir. 



1772. C. pictonensis, n.s. (Sharp ; Trans. Eoy. Dub. Soc., 

 1886, p. 364.) Niger, antennis pedibusque leete runs ; prothorace 

 cordato, secunduin latera fortiter depresso, angulis posterioribus 

 argute rectis ; elytris fortiter profundeque punctatis, apicibus pro- 

 longatis, interstitio secundo ante apicem puncto unico notato.

This species is distinguishable by the bright-coloured legs and 

 antennae, the deep striation of the elytra, and the very cordate 

 thorax, whose hind angles are sharply rectangular ; the lateral mar- 

 gin of the thorax appears much elevated, owing to a depression ex- 

 tending parallel to it, and within this there is a second curvate 

 feeble impression ; the surface near the hind angles is greatly 

 depressed, the median channel and the anterior transverse impres- 

 sion very deep ; there is no distinct punctuation or rugosity. The 

 very deep elytral striae are, when strongly magnified, seen to be only 

 very indistinctly punctured ; their apices are gently sinuate, and a 

 good deal prolonged. The tooth of the mentum is entire, but broad 

 and truncate at the apex ; the fourth joint of the hind tarsus feebly 

 emarginate, the surface of the tarsus deeply on each side of the 

 middle, and with a less distinct lateral groove. 



This is readily distinguished from Anchomenus helmsi, which has 

 similarly-coloured legs and antennae, by the remarkably deep stria-
