Australian and Tasmanian CVyptocephalides. 421 



ITah. Queensland : Mackay (0. French). 



A short broad species at first sight apparently belonging 

 to Lachnabothra, and possibly really an aberrant member 

 of that genus ; but I have placed it here amongst other 

 aberrant species as being less likely to cause confusion. 

 There are four females before me, in one of which the elytra 

 are almost as brightly coloured as in the unique male. 



Cryptocephalus comosus, n. sp. 



9 . Elliptic-oblong, opaque. Black ; elytra (extreme base and 

 shoulders e-vcepted) pale testaceous ; basal joints of antennse ob- 

 scurely diluted with red. Densely and uniformly clothed with 

 short pubescence — golden on the upper, silvery on the lower 

 surface. 



Head and prothorax with rather small Init very dense and regular 

 punctures. Antennae long and thin, passing ajjex of body, second 

 joint about one-third the length of third, third distinctly shorter 

 than fifth. Prothorax with the oblique impressions indistinct but 

 fairly deep, margins narrow. Scidellum as long as wide ; densely 

 punctate ; ridged along middle, base not very much wider than apex, 

 and with a rather large notch. Elytra oblong, subhumeral lobes 

 small ; with regular series of punctures from base to apex ; interstices 

 wide, feebly convex, and densely and finely punctate. Pygidium 

 strongly bilobed at apex. Apex of prostermim very wide and 

 truncate, but in middle with a scarcely perceptible notch. Abdomen 

 with second and third segments large, fourth very decidedly trisinuate 

 at apex ; fovea without lateral extensions. 



Length 6| mm. 



Hah. Queensland : Tambourine (type in H. IIHdge's 

 collection). 



A very distinct species having pallid and densely pu- 

 bescent elytra, strongly bilobed pygidium and the fourth 

 abdominal segment trisinuate. Its only previously de- 

 scribed hairy congener from Australia is Cr. hispidus, Chp. 

 (unknown to me), which has blackish-blue elytra and 

 pallid abdomen and pygidium. 



Cryptocephalus convexicollis, n. sp. 



(Plate XXVI, fig. 195.) 



^ . Elongate elliptic-oblong, highly polished. Of a fiery metallic 

 copper colour, suture and under-si\rface with a greenish gloss, 

 antennse black.
