OF NEW ZEALAND. 1283 



of small punctures, the surface there is transversely rugose and the 

 interstices become flattened ; the vertical sides are punctate-striate, 

 and the interstices are more or less raised. Tibia with fine fuscous 

 hairs, the posterior longer than the others ; third tarsal joint cleft 

 almost to its base ; claws much bent. 



Length, 3|- ; breadth, 1^ lines. 



Wellington. Mr. G. V. Hudson gave me the only specimen he 

 could find. It was taken off the trunk of a tree at Karori. 



Gastrosarus. 



2258. G. urbanus, n.s. Nitid, head and thorax nigro- 

 violaceous ; elytra fusco-testaceous at base, gradually becoming rufo- 

 violaceous behind; antennae (except shining punctate basal two 

 joints) infuscate*black, very opaque, densely covered with minute 

 ash-coloured hairs; legs chestnut-red, tibiae infuscate towards the 

 extremity, tarsi fuscous ; palpi reddish. 



Head as broad in line with the eyes as the widest part of thorax, 

 very finely punctured. Thorax longer than broad, widest behind the 

 middle, where the sides are obtusely dilated, between that point 

 and the base a second smaller swollen spot is situated more on the 

 upper surface, and a third in front of the middle one ; it is a good 

 deal narrowed behind, and deeply but not widely constricted near 

 the basal margin ; towards the front it is more gradually narrowed, 

 but more constricted ; disc uneven, with a transverse fovea-like de- 

 pression near the base at the middle, and two obsolete elevations 

 near the middle ; it is finely punctured, and clothed with fine, de- 

 cumbent, ash-coloured hairs, and with some scattered long erect 

 ones. Scutellum broad, blackish. Elytra wider than thorax at base, 

 gradually attenuated posteriorly, so that they are only half the 

 breadth of the basal portion at the extremity, apices subtruncate, 

 but acutely spinose at the suture, and with the external angle obtusely 

 produced ; there is a long shallow depression on each elytron, the 

 punctures are distinct but less numerous behind. Underside nigro- 

 violaceous. Legs with fine erect hairs, two front pairs short, 

 posterior very long with curvate tibiae. 



This seems quite different from the typical species; the colora- 

 tion, and punctuation of the head, are dissimilar.

 near Drury. Fern, incog. 



2259. G. lautus, n.s.. Glossy, head and thorax violaceo-rufous ; 



. scutellum dark ; elytra testaceous, but, at the extremity, tinged 

 with violaceous ; legs rufo-fulvous ; antennae black, opaque, first 

 two joints shining, somewhat violaceous ; abdomen in colour similar 

 to the legs, the sternum more violaceous. 



I think I am right in regarding this as distinct from G. nigri- 

 collis. The head is very finely and not coarsely punctured. The 

 thorax is quite as broad as the head, uneven above, finely punc-
