OF NEW ZEALAND. gjl 



1650. E. obnisus, n.s. Convex, shining, castaneo-rufous, tarsi 



fulvous, sparingly clothed with greyish-yellow hairs. 



Head shorter than but nearly as broad as thorax, punctate, the 

 inter-ocular foveas continuous with a depression occupying most of 

 the surface, the occipital portion appearing like an abbreviated tri- 

 angular projection ; eyes distinct. Antenna} almost as long as head 

 and thorax, their two basal joints about equal in length ; the second 

 more slender and bead-like than first ; third rather longer than 

 fourth ; joints 4-8 not very appreciably different, quadrate ; ninth 

 and tenth strongly transverse and a good deal larger than the pre- 

 ceding; eleventh large. Protliorax oviform, its length and breadth 

 about equal, with shallow obsolete punctation ; the median channel 

 deep from base to apex, the three ante-basal foveas united. Elytra 

 oblong-quadrate, their sutural stri^ and intra-humeral impressions 

 well marked, but without other obvious sculpture. Legs stout, 

 tibiae arcuated externally. Hind-hody as broad as the wing-cases, 

 pubescent, not perceptibly punctured. 



More convex than No. 259 (E. sculpturatus), broader, the depres- 

 sion on the head nearly similar but sculptured, the sides of the head 

 not straight and obtusely elevated as in that species, and the inter- 

 antennal portion plane. 



Length, f line ; breadth, J. 



Found on the Waitakerei Eange. 



1651. E. vacuus, 'z^-s- Sub-depressed, not very glossy, elytra 

 and abdomen rather densely covered with short, depressed, greyish- 

 yellow hairs, of a chestnut-red colour, elytra, legs, and antennae 

 paler, palpi and tarsi fulvous. 



Head trigonal, not so broad as thorax, with two large, isolated 

 foveas on the vertex, frontal tubercles small, no part much elevated ; 

 eyes rather small. Antennce nearly the length of head and thorax, 

 the two basal joints stout ; second longer than broad ; third as long 

 as broad ; joints 4-8 about equal, transversely quadi-ate ; the follow- 

 ing two transverse, nearly twice the bulk of the eighth ; eleventh 

 large. Prothorax transversal, rounded laterally, the foveas near the 

 posterior angles large and deep, and joined together by an angulated 

 depression which does not form a well-marked central fovea ; dorsal 

 sulcus short, like an elongated fovea ; its surface with a closer but 

 shallower punctation than the head. Elytra oblong, large, sutural 

 strise broad, the basal impressions not distinctly prolonged back- 

 wards. Abdomen as long as the wing-cases, and, like them, without 

 evident sculpture. 



I believe this species to be unique so far as the structure of the 

 antennas is concerned, no other that I know having the intermediate 

 articulations so transversal ; the large lateral fovege cause the sides 

 in front of the thorax to appear swollen, after the fashion common 

 in the genus Sagola. 



Length, f line ; breadth, nearly 1. 



Detected at Paparoa (Howick). 



1652. E. incomptus, n.s. Shining, sparsely clothed with fine, 



12 — PT. IV.
