Tetrorea. 



White; Voy. Er. Terr., Ins., p. 21. 



Head notched between the antennae ; antenna with the fourth joint 

 longest and slightly curved, each joint ciliated on the inside ; thorax 

 short, rather longer than wide, with four tubercles ; two transverse in 

 the middle, two larger, one on each side ; elytra elongated, at the base 

 abruptly inserted, the shoulder angled, and between the shoulder and 

 the suture there is a tubercle, end of elytra bluntish; legs with the 

 femora very thick. 



1068. T. Cilipes, White; Voy. Er. Terr., Ins., p. 21. Elytra at 

 the base and on the margin punctured, a line of punctures close to 

 the suture extending to the middle of the elytra, near which, on each 

 side, is a small tuft of light-coloured hairs ; head and thorax with ochrey 

 hairs ; antenna grey, sprinkled with brown ; base of elytra deep brown, 

 with two streaks of yellowish hairs ; elytra yellowish-brown, on the sides 

 spotted with blackish, near the apex is an oblique grey spot, sprinkled 

 with black, the fore part margined with a curved line, white in front and 

 ochrey behind ; under-side of abdomen dark grey, four of the segments 

 with a yellow spot on each side ; tibia on each side near the base with 

 two or three tufts of whitish hairs. 



Length, 6f~7 lines. 



NOTE. Mr. White does not give its habitat. I have taken speci- 

 mens at the island Motuihi, Tairua, and Whangarei, and received a pair 

 from Capt. Hutton, which he had found on the west coast of Otago. 



Hybolasius. 



Bates ; Ann. Mag. Nat. Hist., August, 1874. 



Gen. Hebesed affine. Corpus oblongum, tomentosum. Caput re- 

 tractum, fronte quadratum. Antenna corpore paulo longiores, ciliatae ; 

 scapo quam articulo tertio multo breviore, breviter clavato ; articulis 

 terfio et quarto caeteris singulis multo longioribus, hoc paulo curvato. 

 Thorax lateribus tuberculatis. Elytra apice rotundata, basi utrinque 

 cristata. Pedes robusti ; femora clavata ; tibia gradatim dilatatse, inter- 

 mediis vix emarginatis. 



This genus is founded on a common New Zealand insect, the 

 Lamia crista of Fabricius, which White placed in the genus Pogonocherus. 

 It agrees with Pogonocherus in many essential characters such as the 

 structure of the sterna, the form of the sockets of the anterior and 

 middle coxae, and the divaricate claws ; but the antennae resemble much 

 more closely those of Hebeseds and the allied genera, differing chiefly in 

 the shorter and more regularly clavate scape. There is, however, 

 scarcely any difference in the formulae given by Lacordaire of the two 

 groups Hebeseddes and Pogonocherides, although he places them so 

 widely apart. The genus is also closely allied to the Chilian (Ectropsis, 

 placed by Lacordaire in the Exocentrides group.
