Austoxdian and Tasvianian Cryptoceqdudides. 423 



moderately stout, ju.st iihoiit tlie knigtli of body, second joint less 

 than lialf the len<^th of third, third ali<4htly shorter tlian fifth. 

 PniUuiraM more tliaii twice as wide as lonj^ ; witli dense;, round, 

 regular punctures of fairly lar<,'e size, but sparser on disc (where a 

 few smaller punctures are scattered about) than elsewhere ; oblique 

 impressions fairly deep, but interrupted in middle, margins not very 

 narrow. ScAitellnm transverse ; sparsely punctate ; apex wide, base 

 deeply notched. Ehjira oblong, subhumeral lobes small ; with 

 large dense punctures (very sparse on the pallid ])ortions), liecoming 

 pjjarser, smaller (but still ratlier large), and seriate in arrangement 

 posteriorly. Aj)ex of proslenuini wide rounded and entire. Inter- 

 mediate segments of alxlomcn rather strongly incurved to middle. 



Length 5^ mm. 



^ . Differs in having the upper surface of a purplish-red (except 

 that the junction of the prothorax with the scutellum and elytra is 

 black), and the legs (tips of the claws excepted) entirely pale ; the 

 elytral markings are, however, the same. It is larger and wider, 

 punctures smaller, antennai thinner, and just passing hind coxte, and 

 both the prothorax and scutellum more transverse. Abdomen with 

 second and third segments large and with almost straight sutures, 

 fourth encroached upon by fovea ; the latter with very shallow 

 lateral extensions. Length 7^ mm.

An aberrant species and, like tlie last, with an outHne 

 suggestive of PrcmriwiuH. It ap[)ears to be an abundant 

 species in North Queenshmd. The four postniedian .spots 

 (which appear p,s parts of a fa.scia) are .sometimes united to 

 form but two. One peculiarity of the species is the fact 

 that the punctures are very sjjarse (on some s[)ecimens 

 they are altogether absent) on the pallid portions of tlie 

 elytra; those that <lo occur there are more or less 

 infuscate.
