 flavo-pilose, antennae and legs paler ; head moderately elongate, 

 slightly attenuate in front, and having two large foveas placed past 

 the eyes, sulci little oblique, shallow^, vertex carinate, antennal 

 tubercles incised laterally ; antennae slender and elongate, first joint 

 robust, second quadrate, third suboblong, fourth to tenth quadrate, 

 hardly increasing in v^idth, ninth a little longer, eleventh moderately 

 elongate, truncate at base ; prothorax strongly cordate, broader than 

 the head, rounded laterally, emarginate past the middle and narrowed, 

 from there slightly sinuate ; lateral foveas large, deep, median one 

 smaller, transverse sulcus angulate ; elytra elongate, not much 

 broader than the prothorax, parallel laterally, shoulders oblique, 

 well defined and minutely dentate, dorsal sulcus a little longer than 

 the others, the two carinae very short and inclosing hardly the third 

 part of the length of the disk.

 underneath ; ventral abdominal segments deeply impressed trans- 

 versely, the sixth impressed in an oblong shape and sinuate at apex, 

 third to fourth with a sharp point on each side, trochanters with a 

 very short tooth at base, posterior ones armed with a slightly sinuate, 

 apical spine, intermediate tibiae briefly spurred at apex. 

 Female unknown. Length 2-40 mm. 



This species is the largest of the genus, and is easily distinguished 

 by its long and parallel form and slender antennae. 



Hah. Cape Colony (Stellenbosch). Seen one example only. 



Gen. DALMINA, Eafi"r., 

 Eev. Entom., vi., 1887, p. 46. 



One constant characteristic, but an important one, distinguishes 

 this genus from Raffrayia, viz., the joints of antennae have no spines 

 or tubercles, the body is generally longer and more slender, the 

 intermediate joints of the antennae are in both sexes always a little 

 larger than the others, and they have sometimes a distinct median 

 node. 



So far as is known the genus Dalmina is exclusively a South 

 African one.
