536 COLEOPTERA 



the interstices have a row of distant punctures on each ; the second 

 striae are deeply impressed, the three sutural interstices only reach the 

 apex, the others being abbreviated leave an obvious apical cavity or 

 depression. 



The body is nude, but there is some yellowish pubescence on the 

 anterior tibiae and the antennal club. 



It may be easily recognised by its long laterally dilated thorax, 

 gradually attenuated elytra, and large size. 



Length, 2\ lines. 



The species occurs in the forests near Whangarei Harbour. 



952. E. littoraliS, n.s. Cylindrical, elongate, piceous, the thorax 

 reddish, and the legs and antennae dark red. 



The head and rostrum are very finely and rather remotely punctured; 

 the eyes small and not^all prominent. Thorax long, more than half the 

 length of the elytra, its hind angles rounded, the sides very gradually 

 narrowed towards the front, where there is only a very slight constriction, 

 and with its surface minutely and distantly punctured. Elytra cylindric, 

 a little convex transversely, not wider than the thorax, very slightly 

 narrowed behind and feebly striated, but the striae are distinctly punc- 

 tate ; the interstices are almost plane, but the sutural are a little rugose. 



The colouration is variable. I have two specimens of a pale chestnut 

 colour, and others of intermediate hues, but they are generally as des- 

 cribed above. 



The insect may be at once identified by its narrow cylindrical out- 

 line, rather long prothorax and small size. 



Length, ij-ij line. 



I found several specimens adhering to the under-side of a log, on the 

 sea beach at Tairua. 



Xenocnema.
