Bates. — On the Geodephagous Coleoptera of New Zealand 305 



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



Tropopterus seriatoporus, n. sp. 



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

 punctata ; elytris grosse seriatim punctatis. Long. 2 J lin. F, 



The labial palpi are obtuse; the 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 striae, the rest are superficial ; the form of the lateral striae 

 is as in T. sulcicollis. 



Mr. H. Edwards ; one example. 



Cyclothorax insularis. 



Olistliopus insularis, Motschulsky, Bull. Mosc. 1SG4, iv. p. 3*25. 

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



Differs scarcely from the common Australian Anchomenus ambiguus, 



M 



more aeneous colouring. 



Auckland and Canterbury. 



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

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

 no species of either genus from New Zealand. 



Subfamily Pterostichin^e. 



Prosopogmus im2)ressifro?is, 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 PL {Trichostemus) australasice, but much flatter and of a brilliant 



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



reticulated. 



Trichostemus 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. 



Trichostemus rectaywulus, Chaud. Bull. Mosc 



Christchurch.

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



Christchurch
