70 Descriptive Catalogue [1897. 



This species is found in company within, incerta and B. variabilis, 

 but both sexes are easily distinguished from them by the longitudinal 

 sulcus of the prothorax, which is more or less clearly denned but 

 never entirely wanting, and also by the larger size and darker colour. 

 The males are at once differentiated by the impressions on the under 

 side of the head. 



Hab. Cape Colony (Newlands — neighbourhood of Cape Town). 



Raffrayia ceuciata, 

 Plate XVI., fig. 7. 



Oblong, rather convex, ferruginous, clothed with a moderately 

 long flavous pubescence, last joint of antennae of a paler hue ; head 

 attenuate in front, sides oblique, between the eyes, which are 

 moderately large, are two foveas, the two sulci are little elongate, but 

 oblique, the vertex is carinate ; antennas short, thick, second joint 

 quadrate, third briefly triangular, fourth to eighth strongly trans- 

 verse and decreasing, ninth slightly transverse, smaller, tenth 

 slightly transverse, larger than the preceding one, eleventh sub- 

 quadrate at base, cone-shaped at apex and acuminate ; prothorax 

 broader than the head, narrower than long and slightly cordate, 

 lateral foveas sulciform, longitudinal sulcus deep, entire, the 

 transverse one straight ; elytra subquadrate, hardly attenuate at 

 base, shoulders nearly quadrate and dentate, vaguely and sparsely 

 rugose ; abdomen longer than the elytra, first dorsal segment large, 

 deeply impressed transvers®ly at base, the impression covering a 

 third of the disk. 



Male : Metasternum and last ventral segments impressed, the first 

 slightly, the second broadly. 



Like B. armata and B. nasuta, B. cruciata has a longitudinal 

 sulcus on the prothorax, but it is deeper, more defined, and similar 

 in size to the transverse one, which is straight, both sulci cutting 

 thus into one another at right angles. The size is larger, the 

 antennas stouter, the prothorax less cordiform, the elytra shorter, 

 with the shoulders well marked and nearly square. 



This species seems rare. I have seen only one pair, which I 

 found under stones near Cape Town.
