OBDEMERIDAB. 53 



Antennae stout, reaching to just beyond the intermediate femora ; 2nd 



joint evidently shorter than 3rd, which is only a third shorter than the 4th. 



Tarsi with the 3rd joint of the anterior pair rather short and triangular ; 



.4th rather large, with short lobes; basal joint of the posterior elongate 



and slightly arched above ; the claws with 2 distinct teeth. 



The sculpture of the head is just the reverse of that of T. concolor, and 

 that of the el}^ra is not " transversely confluently rugose," and the antennal 

 structure differs. In T. attenuata there is a frontal median impression on 

 the thorax of which there is no sign in T. rugicoUis, but instead there are 

 several distinct, though narrow, almost smooth lines which do not exist in 

 the other two species alluded to.

Waimarino. January, 1909. A single individual only. 



3115. Techmessodes cephalotes sp. nov. Gen., Man. N.Z. Coleopt.. 



p. 1173. 



Elongate, depressed, with slender cinereous pubescence ; variegate, mode- 

 rately shining ; head and elytra black, thorax yellow, legs pale-brown, 

 tips of femora and basal portion of tibiae fusco-testaceous, antennae fusco- 

 niger but with the base of joints 4 to 11 pallid. 



Head, including the large eyes, twice the breadth of the front of thorax, 

 much narrowed behind, abruptly so in front, so that the epistome and 

 labrum appear very small ; it is distinctly but not closely punctured. 

 Thorax relatively small, only about half the width of the elytra at the base, 

 still narroAver in front, slightly transverse, its sides moderately rounded at 

 the middle ; the surface moderately coarsely and irregularly punctured. 

 Seutellum. blackish. Elytra elongate, very gradually and slightly widened 

 behind ; moderately coarsely, closely, and somewhat rugosely punctured. 



Antennae fiUform, extending backwards beyond the posterior femora ; 

 2nd joint very short, hardly as long as broad ; 3rd not quite the length of 

 the 4th : in the female they just attain the hind thighs. 



Undoubtedly allied to T. versiciJ^- ; in it, however, the seutellum is 

 yellow, the antennae are less slender and only reach half-way down the 

 elytra, the head is much narrower, and the eyes are smaller. 



Underside shining, black, finely punctured and pubescent ; coxae pallid ; 

 prosternum flavescent.

3116. Exocalopus nitidiceps sp. nov. Gen., Man. N.Z. Coleopt., p. 1170. 



Depressed, with very scanty and slender ash-coloured pubescence ; head 

 and thorax intensely black and glossy, elytra moderately shining black, 

 palpi and antennae nigro-fuscous, legs fuscous, the knees paler. 



Head much narrowed behind, and, including the large eyes, slightly 

 broader than the thorax ; it is closely and moderately finely punctate, the 

 vertex, however, is almost impunctate and polished. Thorax strongly trans- 

 verse, base and apex subtruncate, its sides rounded and without definite 

 angles ; its surface uneven, there being a large irregularly shaped depression 

 at each side, with the basal and inner borders nearly smooth and polished, 

 and a small one near each posterior angle ; the middle and sides are finely 

 yet distinctly punctured, but the front is nearly smooth. Seutellum punc- 

 tate. Elytra about double the width and six times the length of the
