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



Chapuis, is that the serrations of the antennae are reversed 

 after the 7th joint. 



The male has usually on the prothorax a large sub- 

 triangular black median patch (the narrow end touching 

 the base) ; in the female the patch is sometimes widest in 

 the middle and broad at the base, the part in front being 

 reduced to a point, or frequently it appears as a narrow 

 streak. The dark fasciae on the elytra are deep black and 

 sharply defined in the male; in the female they are much 

 less sharply defined and are occasionally absent. In two 

 females under examination the abdomen and legs (except 

 the penultimate joint of all the tarsi) are entirely pallid.

Cryptocephalus pcecilodermis, Chp. 



A pretty and somewhat variable species. A female from 

 Somerset, measuring 8 mm., has the metasternum slightly 

 infuscate and the punctures surrounding the scutellum 

 stained with black instead of brown. The prothorax, 

 elytra and scutellum are narrowly edged with black or 

 dark brown (a character not mentioned by Chapuis). 



Specimens in the Macleay Museum from N. W. 

 Australia are smaller ( $ 5^, ^ 6i mm.) and paler than 

 those from Queensland, and the punctures on both 

 prothorax and elytra are smaller. 



Two males before me have the fifth abdominal segment 

 unusually large, and with a wide and not very shallow 

 excavation occupying the greater portion of its surface, 

 this excavation is of a totally different character to the 

 apical fovea of the female, and is not bordered with hairs. 

 Seen from above the excavated segment appears to be the 

 fourth, but the fourth is visible only from the sides, each 

 side of it appearing as an isosceles triangle. 



A female measuring 8 mm. from Port Darwin (in the 

 Macleay Museum) I hesitate to regard as more than a 

 variety of this species ; it differs, however, from a female 

 from Port Denison (the original locality) in having the 

 vertex infuscate and with larger and in places confluent 

 punctures, the prothoracic punctures larger and not stained, 

 the elytral punctures larger and more deeply stained, 

 the stains more confluent and the pallid spaces more longi- 

 tudinal and maze-like in appearance, not, as in the type,
