254 MR. M. .TACOBY ON THE [Feb. 2, 



Head strongly rugosely punctured, black, sparingly pubescent ; 

 the anterior portion of the clypeus flavous ; antennae extending to 

 the middle of the elytra, slender, black, the basal joint flavous 

 below, the third joint slightly shorter than the fourth ; thorax with 

 the sides almost straight, much narrowed anteriorly, the surface 

 strongly and closely punctured, especially at the sides, flavous, the 

 middle of the disc ^vith a broad transverse black band, the posterior 

 margin of which is produced at each end and at the middle into a 

 point ; scutelluin broadly triangular, its surface flattened ; elytra 

 with strong and regular rows of punctures, the interstices finely 

 transversely wrinkled, flavous, all the margins very narrowly black, 

 the shoulders with a black spot, which is more or less connected 

 with another one near the scutellum, forming a short semi-inter- 

 rupted band, another spot placed below the middle occupies about 

 five rows of punctures in a transverse sense ; the underside, pygi- 

 dium, the femora, and the tarsi (partly) black ; the anterior femora 

 more or less flavous below.

 British Museum and that of my own. 



This species differs from most of its African congeners in the 

 strongly and closely punctured thorax in connection Mith the 

 transverse band of the latter ; in respect to the latter, there are 

 not many species which are similarly marked ; the sculpturing of 

 the elytra also differs from most African CryptoeephaUnoi, so that 

 the species will not be very difficult to recognize. In the varieties, 

 the black colour of the thorax predominates to such an extent as 

 to leave the margins only of the flavous ground-colour, this latter 

 being always wider, however, at the sides in all the forms; the 

 elytral spots are likewise often reduced to one only, and are pro- 

 bably entirely absent occasionally ; there are, however, only these 

 three varieties before me, amongst the six specimens obtained by 

 Mr. Marshall. 



Cbyptocephalus decemnotattjs, Suffr. 



Of this very variable species, an interesting variety was obtained 

 by Mr. Marshall in Mashonaland amongst the typical form with 

 three elytral black spots. In this variety the spots are more or less 

 enlarged, so as to form elongate short stripes, which in one speci- 

 men form a sutural and a transverse black band below the middle ; 

 this latter band has its upper margin deeply concave between each 

 row of punctures. This variety has not been mentioned by Suffrian. 

 The other chai-acters peculiar to the species, viz. the four thoracic 

 black spots and the punctured interstices of the elytra, are all 

 present in this variety, thus proving its identity vAith the type. 



CrTPTOCEPHALTJS NIGBOSUTUEALIS, n. Sp. 



Black ; the anterior margin and sides of the thorax flavous, 

 the disc very finely rugose ; elytra strongly punctate-striate and 

 finely wrinkled, flavous, a spot on the shoulder and a broad sutural 

 band, narrowed behind, black.
