Bates. — On the Geodephagous Ooleoptera of New Zealand. 305 



One example, female, sent by Mr. Fereday from Christchurcli. 



Tropopterus seriatoporus, n. sp. 



T. ovatus, elytris gibbosis ; castaneo-rufus, nitidus ; tborace basi grosse 

 punctate j elytris grosse seriatim punctatis. Long. 2J lin. F, 



The labial palpi are obtuse ; tbe maxillaries taper to a point almost as in 

 Oopterus. The posterior narrowing of the thorax is strongly sinuated and the 

 hind angles produced ; the whole base is very coarsely punctured ; the dorsal 

 line and long basal fovese are deeply impressed. The sutural rows of punctures 

 are impressed in strise, the rest are superficial j the form of the lateral striae 

 is as in T. sulcicollis. 



Mr. H. Edwards j one example. 



Cyclothorax insularis. 



OUstliopus insularis, Motschulsky, Bull. Mosc. 1864, iv. p. 325. 



Drimostoma striatopunctata, Casteln. I. c. p. 199 (?) 



Differs scarcely from the common Australian Anchomenus amhiguus, 

 Erichs. (Cyclothorax id., W. M'Leay), the only difference observable beiug its 

 more aeneous colouring. 



Auckland and Canterbury. 



Drimostoma antarctica, Casteln. ?. c. p. 199. 

 M. de Chaudoir suspects this to be an Ahacetus. I have seen at present 

 no species of either genus from New Zealand. 



Subfamily PTEROSTiCHiNiE. 



Prosopogmus impressifrons, Chaudoir, Bull. Mosc. 1865, p. 28 (sepaiata). 



A large species, about 8 lines long, which I have not seen. It is similar 



in form to JPt. {Trichosternus) australasice, but much flatter and of a brilliant 



brassy coppery hue, with flattened tarsi, having their upper surface finely 



reticulated. 



Trichosternus antarcticus, Chaudoir, Bull. Mosc. 1865, iii., p. 73. 



Megadromus viridilimbatus, Motsch. Bull. Mosc. 1865, iv., p, 251. 



This fine insect was sent home in some numbers, from Christchurch, by 

 Mr. Fereday. The colour is not always cupreous, but some specimens are 

 black, with the green margins occasionally scarcely perceptible. It may 

 always be distinguished from the obscure-coloured T. rectangulus by its larger 

 and broader shape, more protuberant cheeks behind the eyes, and by the 

 thorax being more dilated in front. 



Trichosternus rectangulus, Chaud. Bull. Mosc. 1865, iii., p. 74. 

 Christchurch. Sent both by Mr. Eereday and Mr. Wakefield. 



Trichosternus capito, White, I. c. p. 4. 



Closely allied to T. rectangulus ; but I have seen no specimens from 



Christchurch exactly resembling White's types in the British Museum.
