African Phytophagous Goleoptera. 171 
Cryptocephalus araticollisj Cliap. 
A specimen from Delagoa Bay in the Cape Town 
Museum agrees almost entirely with Chapuis^ description, 
but the raised interstices of the elytra are flavous, of 
which Chapuis says nothing ; the punctures are more or 
less arranged in two rows, and are very deep, of a dark 
brown colour ; the antennae are black, with the lower five 
joints flavous. This species is much distinguished by the 
longitudinal strig^e of the thorax, which mark its entire 
surface. The anterior and lateral margins of the thorax 
in the specimen before me are likewise flavous. Chapuis' 
specimen was probably a variety, but may possibly be 
distinct. 
Gryptocephalus sinuato-vittatuSj sp. n. 
Pale fulvous, varied with flavous, the terminal joints of the 
antennae and the breast black; thorax longitudinally strigose; elytra 
flavous, strongly punctate-striate, the basal and sutural margins, a 
spot near the scutellum and a strongly angulate and sinuate lateral 
stripe, black. Length, 1;^ line. 
Head flavous, impunctate, the base of the antennae and the 
lower parts of the face darker ; antennae very slender, the lower 
five joints fulvous, the others black, the third joint slightly shorter 
than the fourth ; thorax about twice as broad as long, the entire 
surface covered with longitudinal regular strife from the base to 
the apex, fulvous, the anterior and lateral margins and two trans- 
verse spots in front of the scutellum at the base, flavous ; scutellum 
strongly raised, black, its apex truncate ; elytra slightly narrowed 
posteriorly, flavous, very deeply and regularly punctate-striate, the 
punctures round and large at the base, diminishing posteriorly and 
scarcely perceptible at the apex within the striae, the interstices 
convex, flavous, the extreme basal and sutural margins black ; a 
rounded spot near the scutellum, another near the apex, and a 
longitudinal narrow stripe from the shoulder, curving inwards near 
the suture, and joined to the apical spot, dark piceous ; prosternum 
bi-lobed, flavous as well as the abdomen and the legs, breast black. 
Ilab. Delagoa Bay, Cape Town Museum; a single 
specimen. 
In the peculiar sculpture of the thorax, this species 
entirely agrees with G. araticolUs, Chap. It difi'ers 
totally from that species in the colour and pattern of the 
elytra.
