 Mount Albert on the 6th October, 1916. 



Crisius Pascoe. Man. N.Z. Coleopt., p. 500. 



4232. Crisius dives sp. nov. 



Convex, subovate, widest at the shoulders, subopaque ; piceous, rostrum, 

 antennae, and tarsi dark fusco-rufous ; covered with depressed, small, 

 variegated squamae, most of these are rufous, but along the middle of the 

 elytra they are more fulvescent, those between the middle and sides of 

 thorax are also fulvescent but more elongate, usually there is a small flaves- 

 cent patch near the middle of the femora. 



Rostrum stout, arched, a little dilated near the base, almost as long as 

 thorax, nearly bare and finely punctate in front. Thorax nearly a third 

 broader than long, its frontal half abruptly contracted, rounded and obtusely 

 bicristate at apex ; its basal portion with a pair of similar crests in front, 

 these however are obliquely prolonged to the base, the crest at each side in 

 front is more prominent than the central pair ; disc apparently closely punc- 

 tate and with a blackish carina, from base to apex. Scutellum small. Elytra 

 cordiform, 2| times the length of thorax, their somewhat elevated, rounded 

 shoulders are rather broader than the thoracic base, they are gradually yet 

 evidently narrowed and nearly vertical behind ; dorsum moderately coarsely 

 seriate-punctate, the sides more coarsely ; third interstices indistinctly and 

 interruptedly elevated before the middle but terminating as distinct 

 elongate horizontal nodosities on the top of the posterior declivity, just 

 below each of these there is a minute one, and a longer crest near the apex, 

 on the fifth there are three small elevations, which however are more con- 

 spicuous than others near the base, some of which have grey scale-. 



Femora dentiform underneath ; tibiae bent above, the hind pairs fringed 

 externally with dark scales above the middle ; tarsi normal, rather narrow. 



Scape implanted before the middle, flexuous and gradually incrassate ; 

 second joint of funiculus hardly any longer than the thicker basal, joints 

 3-6 shorter and subequal, seventh broader ; club moderately elongate, 

 quadriarticulate. 



Underside nigrescent, with minute rufous squamae. Raised borders of 

 pectoral canal extending as far as the back part of middle coxae. .Basal 

 ventral segment irregularly punctate, depressed in front, of about the same 

 length as second, which is but little longer than third and fourth together. 



This richly coloured species is distinguishable by the posterior pro- 

 longation of the central thoracic crests. 



Length (rostrum exclusive). 4^ mm. ; breadth, 2 1 mm. 



Wadestown, near Wellington. A Bingle example, sent to me on the 10th 

 August, 191*;. by Mr. A. C. O'Connor. 



4233. Crisius longulus sp. nov. 



Opaque, irregularly oblong-oval, only moderately convex ; nigro-fuseous, 



antennae and tarsi fusco-rufous ; covered with depressed, principally greyish- 

 tawny squamae, those on the rostrum and lower sides of thorax more fulves- 

 cent; legs variegate, the hinder pairs of femora having broad grey and 

 fuscous bands.
