Aiistralian and Tasmanian Cryptocephalides. 401 



Cryptocephalus variipennis, n. sp. 

 (Plate XXV, fig. 146.) 



$ . Elongate-oblong. Eeddisli-testaceous ; pygidiiim and abdo- 

 men flavous ; antennas, a rather wide and continuous vitta on pro- 

 thorax, scutellum and a subtriangular space behind it, the shoulders, 

 a spot at apical third (rather close to suture), tarsi and apex of tibise 

 black. 



Head densely and coarsely punctate, punctures more or less con- 

 fluent at base and sides of eyes ; with a distinct median impression. 

 Antennae rather thin, second joint less than half the length of third, 

 fifth subequal, sixth-ninth wider (the others missing). Prothorax 

 with rather large irregularly distril^uted punctures, sparser and 

 smaller on disc than elsewhere ; oblique impressions very indistinct ; 

 margins narrow. Scutellum subtriangular, longer than wide, apex 

 rather narrow but truncate, base deeply notched. Elytra elongate- 

 oblong, subhumeral lobes small ; basal third with rather large but 

 not very dense punctures and with transverse rugulosities, elsewhere 

 the punctures are smaller and regular and posteriorly separated 

 by distinct convex interstices. Apex of prostermiin wide, rather 

 strongly bilobed and with large punctures. 



Length 4 mm. 



$ . Differs in having somewhat smaller punctures, the antennte 

 shorter and prothorax rather more transverse ; the third abdominal 

 segment is larger than usual, the fourth distinct across middle but 

 considerably encroached upon by fovea, the latter large and deep 

 without lateral extensions. 



Length 6j mm. 



Hah. S. Australia ; W, Australia : King George's 

 Sound (Macleay Museum), Swan River {A. M. Lea). 



In two females before me the antennse are perfect and 

 pass the third coxae for a slight distance ; judging by the 

 joints that are left in the male, I do not think its antennse 

 would pass the apex of the body. A male from King 

 George's Sound, in the Macleay Museum, differs in having 

 all the elytral markings conjoined and the basal half of 

 the head black, the sixth-eighth joints of its antennse are 

 also diluted with red ; a female from S. Australia has a 

 small spot at the base of the head, and the suture from 

 the base to be^^ond the middle (where it joins with the 

 sub-apical spots) black, but the humeral spots are isolated ; 

 its antennse have also the sixth-eighth joints paler than 

 the others.
