410 Mr. A. M. Lea's Notes on 



Cryptocephalus tenebricosus, n. sp. 



$ . Rather feebly shining. Blackish-l)rown ; head (basal fourth 

 excepted), antennte (upper surface of first joint excepted), margins 

 of elytra (the apex rather more widely than the sides), pygidium 

 and legs (middle of femora and apex of tibiae excepted) of a more 

 or less obscure testaceous- red. 



Hecid densely and coarsely punctate throughout, with a very 

 feeble median impression. Antennte rather thin, just passing hind 

 coxae, second joint more than half the length of third, third very 

 little longer than fourth and slightly shorter than fifth, eleventh 

 inserted towards side of tenth. Prothorax more than twice as wide 

 as long ; densely and coarsely punctate throughout ; oblique im- 

 pressions rather feeble, margins very narrow and entire. Scntelln/m 

 rather strongly transverse, base entire and not much wider than 

 apex ; a few punctures towards base. Elytra oblong, subhumeral 

 lobes rather small ; coarsely and not very densely punctate ; apical 

 half with distinct costiform interstices. Pygidium with an indistinct 

 median ridge. Under- surface densely and moderately coarsely 

 punctate. Apex of prosternum wide and feebly bilobed. Abdomen 

 with the fourth segment fairly large but in middle encroached upon 

 by fovea, the latter wide, without lateral extensions. 



Length 4f ram. 



Hah. Queensland: Ipswich (types in Macleay 

 Museum). 



A dingy species with the apex of the prosternum feebly 

 bilobed but which would look more at home in Cadmus. 

 I was inclined at first to regard it as an extreme variety of 

 Cad. ornatus, Clip, (which in build it much resembles), but 

 apart from the prosternum and colour it differs in having 

 the prothoracic margins decidedly narrower and the elytra 

 more rugose. 



Cryptocephalus distortus, n. sp. 

 (Plates XXV, XXVI, figs. 148, 192.) 



(?. Elongate-oblong, feebly shining. Almost (parts of the under- 

 surface quite) flavous ; a triangle at base and parts of the front half 

 of head, antennas (base of second — fourth joints excepted), a triangle 

 on prothorax (its base almost touching the apex of that segment) 

 and extreme base, all the margins (including suture) of elytra verj^ 

 narrowly, scutellum, metasternum in parts, and legs (coxae and base 

 of tibiae excepted) black. 



Head densely and coarsely punctate ; with a transverse and a
