80 Descriptive Catalogue [1897. 



rounded, two foveae between the eyes and two anterior sulci joined 

 in the frontal part ; antennal tubercles conspicuous, antennae strong, 

 differing in each sex, last joint testaceous ; prothorax cordate, larger 

 than the head and sinuate past the middle owing to the presence of 

 a lateral fovea ; transverse sulcus very angular ; elytra attenuate at 

 base, shoulders oblique, sides slightly rounded, base bifoveate, 

 sutural stria entire, discoidal sulcus broad but short, the three first 

 abdominal segments decreasing very little in length. 



Male : More parallel than the female, and paler, disk of elytra 

 redder ; first joint of antennae a little larger than the others, conical, 

 second ovate, third nearly transverse, fourth a little longer than 

 the preceding one, slightly produced inwardly, sharp under- 

 neath, fifth largest of all, transverse, irregularly rounded inwardly, 

 produced outwardly and obtuse, sixth to tenth quadrate, slightly 

 transverse, each one of them slightly larger than the third, last one 

 hardly broader than the penultimate one, but longer, ovate, truncate 

 at base and acuminate at tip ; elytra nearly twice the length of the 

 prothorax, less attenuate at base than in the female, shoulders 

 oblique and very well defined ; metasternum plane, foveate at apex, 

 last ventral segment much impressed in an oblong shape ; posterior 

 tibiae with an apical spur. 



Female : More attenuate in front, darker chestnut red all over ; 

 first three joints of antennae similar to those of the male, fourth 

 trapezoidal, slightly transverse, not longer than the preceding one, 

 but broader, fifth of the same shape as the preceding one but never- 

 theless a little larger, sixth to tenth smaller, slightly transverse, 

 ultimate one as in the male ; elytra shorter, attenuate at base, and 

 almost without shoulders ; metasternum slightly convex, minutely 

 foveate ; legs simple. Length 1-60-1 "80 mm. 



Allied to D. glohulicornis, which has also a node in the median 

 part of the antennae, but whereas the node in this species is formed 

 by the dilatation of the fourth and fifth joints, in D. gratituclinis it is 

 the fifth joint alone which is so dilated. 



Hah. Cape Colony (Stellenbosch — banks of the river. February). 



Dalmina concolor. 

 Oblong, thick, entirely chestnut brown, covered with a brief, 

 greyish pubescence, antennae and legs rufous ; head short and 

 attenuate in front, broad, slightly transverse, two foveae not much 

 apart from one another, sulci straight and coalescing in the frontal 

 part, which is a little depressed, posterior part a little retuse ; 

 antennae of moderate size, first joint large, second quadrate, third 

 obconical and a little narrower, fourth quadrate, fifth quadrato-
