Genera and Spea'es of New Zealand Culeoptcra. 123 



Described from an old imperfect specimen, marked A, 

 ■o'liieh was given to me by Mr. Marshall many years ago. 

 As no other example has been found since then, I thought 

 it advisable to describe it. 



Group Cryptorhyiichidse. 



Crisius dorsaVis, sp. n. 



Variefjate, piceons, rostrum and legs reddish. 



lioslrum stoutj nearly as long as the bead and thorax, its 

 base with rufescent squamte, the sculpture linear, but finely 

 punctate at tlie extremity. Thorax slightly transverse, its 

 apical third constricted and bearing a pair of small obtuse 

 crests, the basal portion closely and coarsely punctured and 

 nearly covered with red scales, there being only a few ochra- 

 ccous ones near each side ; there are two median squamose 

 elevations in front and two smaller ones near the base, which 

 therefore appears as if it were longitudinally depressed ; its 

 sides are a little uneven. Scutellum invisible or very minute. 

 Elytra broader than the thorax at the base, much narrowed 

 posteriorly ; each shoulder has an oblique oblong elevation ; 

 there are seven unequal nodosities along each side, the fifth 

 and sixtii are small, the seventh is placed near the apex ; on 

 the dorsum there are several nodosities of variable size, the 

 squamosity is chiefly ferruginous, but the flattened basal 

 median area is covered w ith minute pallid scales ; on this 

 pale portion and along the hind slope there are fovir series of 

 punciurcs which almost form striae behind ; the external 

 punctuation is interrupted. Lef/s squamose, the tibirc with 

 pale outstanding setiform scales. 



This is smaller than C. obesulus, Sharp, and may be dis- 

 tinguished therefrom by the coarse thoracic punctuation, 

 obsolete scutellum, less dentiform femora, coarsely uneven 

 elytral margins, contracted posterior portion, and by the 

 pale flattened space.
