344 COLEOPTERA 



bisinuated at the base, the sides quite straight though a little narrowed 

 anteriorly ; its surface is finely and rather closely punctured, and the 

 pubescence is more sparing on the middle than elsewhere. Scutellum 

 sub-triangular. Elytra oblong, their shoulders a little elevated, and a 

 little compressed at each side near the middle ; they are finely and 

 closely punctured, with their pubescence chiefly confined to the sides 

 and hind portion. Legs moderate. 



The antenna are remarkable ; they are apparently ten-jointed, but 

 joints three to seven are so minute and closely articulated that it is 

 difficult, if not impossible, to describe them accurately without consider- 

 able magnifying power ; their basal joint is large, deeply excavated 

 behind, and about as long as joints three to seven collectively ; second 

 joint a good deal larger than those which follow ; eighth joint as long 

 as the stalk, produced inwardly at the base in the form of a flexuose 

 tooth, longer than the joint itself; ninth similarly formed, but with the 

 tooth directed forwards, the eighth being bent backwards ; tenth joint 

 longer and much stouter than the ninth, somewhat lunate. The elytra 

 scarcely cover the abdomen, leaving the pygidium exposed. 



Length, ii line; breadth, quite . 



Described from one example found at Tairua ; a second, from the 

 same locality, I sent to Dr. Sharp, but he has not described it. It will 

 probably form the type of a new genus. 



Euderia. 

 Nov. Gen. 



Body very elongate, narrow, transversely convex and squamose. 



Head moderate, eyes large, prominent, rounded, but a little truncated 

 behind and finely facetted. Thorax much longer than broad, consider- 

 ably constricted behind, projecting anteriorly, base truncate, surface 

 tubercular. Scutellum elongate. Elytra cylindrical, broader than 

 thorax, incurved laterally so that the middle is narrowest. 



Legs rather elongate ; tibia sub-linear ; tarsi as long as the tibiae, 

 five-jointed ; the basal joint longest, fourth smallest, fifth elongate, with 

 slender claws. Last joint of the palpi ovate. Antenna ten-jointed, the 

 first sub-pyriform, elongate, second moniliform, joints three to seven 

 small, eighth to tenth forming a loosely articulated club as in Dorcatoma. 



?. 



In the male the first joint is sub-pyriform, and as long as the stalk ; 

 the second moniliform, much stouter than those which follow ; third to 

 seventh minute and closely articulated, so as to be quite indistinguish- 

 able when viewed with a good lens ; the last three very long, filiform, of 

 equal length, and proceeding from a common base, so as to appear as 

 one trifurcate joint or club, these are furnished with very long delicate 

 hairs. 



627. E. squamosa, n.s. Fuscous, antennae reddish. Thorax 

 elongate, its sides almost vertical, widest in front of the middle, consider- 

 ably constricted near the base ; the apex is elevated in the form of a 

 compressed tubercle, there is another tubercle on the middle, and the
