90 COLEOPTERA 



165. G. SOCialis, n.s. Antenna elongate, their three basal joints 

 nearly equal in length, cylindrical, testaceous ; joints four to ten black, 

 slightly and gradually thickened ; eleventh shorter than ninth and tenth, 

 infuscate. Head longer than broad, shining, reddish, not very closely 

 punctured, with a few yellowish hairs ; penultimate joint of the maxillary 

 palpi piceous ; eyes not very prominent and rather small. Prothorax 

 narrow, being rather longer than broad, somewhat convex, a little nar- 

 rowed anteriorly ; of the same colour as the head, sometimes with a 

 long, dark-brown mark on the disc not reaching the apex ; it is finely 

 and rather distantly punctulated, with fine yellowish hairs arising from 

 the punctures. Elytra considerably broader than the thorax, but not 

 longer, widest behind, distinctly notched or sinuated near each hind 

 angle ; they are finely and moderately closely punctured, with pubes- 

 cence very much like that of the thorax, and of a dark smoky-brown 

 colour. Hind-body elongate, gradually attenuated posteriorly, shining 

 castaneous but brownish down the middle, punctulated, and rather 

 densely clothed with yellow hairs. Legs yellowish ; the tibia occa- 

 sionally a little infuscate. 



This and the following species are only temporarily placed in this 

 genus. 



The present one may be readily identified by its narrow prothorax, 

 and by the elytra being notably broader than any other part of the body. 



The colour is subject to considerable variation, sometimes the elytra 

 are reddish-castaneous. 



Length, 2 lines ; breadth, quite J. 



I took several specimens off decaying foliage at Tairua. 



1 66. G. p liber, n.s. Antenna moderately short, stout, not much 

 dilated towards their extremity ; their three basal joints almost equal, 

 sub-cylindrical, and, like the eleventh, reddish ; joints four to ten obscure 

 fuscous. Head narrower than thorax, blackish, shining, somewhat rugu- 

 losely punctate, the sculpture most apparent near the eyes, sparingly 

 clothed with short ash-coloured hairs ; eyes not prominent ; palpi red- 

 dish-yellow. Prothorax convex, about as broad as long, with depressed 

 anterior angles, giving it the appearance of being narrowed in front ; it 

 is red, but, owing to the yellow covering, not glossy ; its sculpture con- 

 sists of irregular linear impressions. Elytra a little broader than thorax, 

 emarginated in front so as to be adapted to the base of the thorax, 

 notched near each hind angle so as to receive the lateral margins of the 

 abdomen, and so sculptured as to appear covered with fine punctures 

 and coarser linear impressions ; in this latter character, as well as their 

 colour and clothing, they greatly resemble the thorax. Abdomen elon- 

 gate, not much attenuated posteriorly, blackish-brown, with red hind 

 margins, distinctly punctulated, and clothed with yellow hairs. Legs 

 red ; tibiae, finely ciliated with yellow hairs, the posterior less so than the 

 others. 



A rather compact, elongate form, suggesting a Philonthus. The 

 insect may be easily recognized by the peculiar elytral sculpture, etc.

 I found one specimen at Parua.
