Australian and Tasmanian Cryptocejohalides. 403 



which (as the apex itself is closely applied to the meso- 

 sternum) at first sight appears to be the true apex. 



Cryptocephalus rubicundus, n. sp. 

 (Plate XXV, fig. 168.) 



(^. Oblong-elliptic. Testaceous; junction of prothorax with 

 scutellum and elytra and the tarsi black, outer half of antennae, 

 suture and metasternum more or less infuscate. 



Head with rather large but not very dense punctures, median im- 

 pression very feeble or absent. Antennae as long as body, second joint 

 half the length of third, third considerably shorter than fifth. Pro- 

 thorax regularly convex, with fairly dense, moderately large and 

 regularly distributed punctures ; oblique impressions scarcely trace- 

 able ; margins narrow. Scvtellum very widely transverse, apex not 

 much narrower than base, base strongly notched. Elytra rather 

 long, subhumeral lobes feeble ; densely but not very coarsely punc- 

 tate, and with transverse rugiilosities, punctures posteriorly becoming 

 smaller and subgeminate in arrangement and close to apex with 

 feebly convex interstices. Apex of prosternum moderately wide and 

 just perceptibly bilobed. 



Length 4^ mm. 



9 . Differs in having shorter and thinner antennae ; fourth ab- 

 dominal segment distinct across middle but encroached upon by 

 fovea ; the latter large and deep with very shallow lateral extensions. 



Length 6 J mm. 



Hah. S. Australia (types in Macleay Museum). 



In the two females before me the legs are uniformly 

 pallid and the metasternum is very slightly infuscate. 

 The colour of the upper-surface is somewhat like that of 

 Or. conjugatus, Chp., and the male of Cr. tcrminalis, Chp., 

 but the prothorax is more convex and regular, the elytra 

 longer with smaller subhumeral lobes and the antennae 

 and punctures different. 



Cryptocephalus rutilans, n. sp. 



9 . Testaceous ; junction of prothorax with scutellum and elytra 

 and the metasternum black ; outer half of antennie and apices of 

 tarsal joints and of tibiae more or less infuscate. 



Head densely but not very coarsely punctate, the interstices finely 

 punctate ; median impression feeble. Antennae passing hind coxae, 

 second joint rather more than half the length of third, third and 

 fifth subequal and not much longer than fourth. Prothorax^ elytra
