2OO COLEOPTERA 



Long., 9 mm. ; lat. elytrorum, 4^ mm. 



This species is just the same length as E. bakewellii, Pascoe, but is 

 considerably narrower, the latter species being about 5^ mm. across the 

 elytra ; in sculpture and clothing the two species are almost identical, 

 but E. wakefieldi has the excision of each side of the base of the thorax 

 considerably longer and narrower. 



This fine species of Colydiida was found by Mr. Wakefield at Peel 

 Forest, March, 1874. 



357. E. rudiS, Sharp ; Entom. Mon. Mag., Jan., 1877, /. 191. 

 Indumenta fusco tectus, supra valde rugosus, prothorace basi utrinque 

 excisione profunda. 



Long., 6 1 mm. ; lat. elytrorum, 4 mm. 



This species differs from E. wakefieldi by the smaller size and 

 shorter form, and its considerably shorter metasternum. From E. bake- 

 ivellii its much smaller size and the deeper emarginations at the base of 

 the thorax readily distinguish it. Though the three forms are so very 

 similar to one another, I think it most likely they will prove to be dis- 

 tinct, and not one variable species, though only the examination of a 

 number of individuals can render this decision satisfactory. 



Christchurch, found by Mr. Wakefield. 



358. E. COntractifrons, n.s. This species is very much like the 

 typical one in sculpture, clothing, and colouration, but differs from it in 

 the form of the thorax, which is almost conical, being considerably, but 

 gradually, narrowed in front, with prominent, sub-porrected anterior 

 angles ; the sides are less explanated, the disc sloping more gradually 

 towards them, and, though there is the usual transverse ridge at each 

 side, there is only one cavity, that is behind, not very deep, and the 

 frontal portion is gradually depressed but not concave; the base is 

 deeply bisinuated as in E. bakewellii. 



The antenna are red, slender, and finely pilose, the third joint longer 

 than the second. The legs are red, and the external edge of the tibiae is 

 ciliated with setae. 



Length, 2| lines ; breadth, ij. 



I found one of this species and three of E. bakewellii at Tairua. 



1 have examined twenty-one specimens of this genus with great care, 

 in the hope of being able to find some corresponding with E. wakefieldi, 

 and E. rudis; these specimens were sent to me by Captain Hutton, from 

 Otago, and Professor Haast, of Christchurch, they differ from one another, 

 more or less, in size, and this is usually accompanied by a slight 

 difference in form, but only in degree, so that there seems to be nothing 

 to warrant their separation as distinct species. 



Syncalus.
