$ . Has the prothorax more transverse ; the abdominal fovea 

 large and deep and wnthout lateral extensions. 

 Length 5j mm. 



Hah. N. S. Wales (Macleay Museum). 



I have referred this species to Crypiorcphalus although 

 the apex of the prosternum is not bilobed, as it would be 

 absurd to refer it to any genus other than that to which 

 Cr.imrcnthcticvs, Suff., belongs; at first sight indeed it 

 appears to be but a variety of that species, but the 

 antennae, prothoracic punctures and apex of prosternum 

 are somewhat different. The colour (except for slight 

 variations on the prothorax and sides of elytra) appears to 

 be constant in the five specimens before me ; the legs are 

 pallid whilst in jxircnthdieiis they are invariably black. 

 The green parts of the elytra (leaving the lateral vittae out) 

 somewhat resemble the letter T, the sutural marking 

 being very narrow at apex, slightly widening out to middle 

 and then rapidly increasing in width to the shoulders. 

 The size and density of the punctures are subject to con- 

 siderable variation and are usually smaller in the female 

 than in the male. The comparative lengths of the second 

 — fourth joints of antennae are rather unusual. In the 

 female as well as in the male the fourth abdominal segment 

 is not traceable across the middle. 



Cryptocephalus serenus, n. sp. 



9 . Almost (abdomen quite) flavoiis ; suture dark metallic bluish- 

 green, the green extended round scutellum (the extreme base of 

 which is almost dark) and at base very narrowly continued almost 

 to the sides ; upper surface of first and the three terminal joints of 

 antenna3 infuscate ; tips of claws black. 



Head with dense but rather small punctures, with a wide indistinct 

 median impression. Antennas just passing hind coxse, second joint 

 half the length of third, third slightly longer than fifth and distinctly 

 longer than fourth. Prothurax about thrice as wide as long ; with 

 moderately dense and fairly large punctures (larger at sides than 

 elsewhere) and with numerous minute scattered punctures ; oblique 

 impressions irregular and indistinct ; margins finely crenulate. 

 Scutellum feebly transverse, base entire and very little wider than 

 apex. Elytra oblong, subhumeral lobes feeble ; not very densely or 

 coarsely punctate, the punctures denser and larger below shoulders 

 than elsewhere, subgeminate about middle and seriate, with feebly 

 convex interstices, posteriorly ; with minute scattered punctures.
