irregular walls, whereas in S. natalcme the punctures are round, 

 and the intervals smooth.

STHONGYLIUM AUSPICATUM, n. sp. 



Very dark blue, with the elytra purplish ; the antennae are also 

 cyaneous, but the five ultimate joints are not shining, they reach the 

 basal angle of the prothorax, and the three penultimate joints are 

 very broad, being slightly more than twice as broad as long ; eyes 

 very broadly separated, surface of head very closely punctate ; pro- 

 thorax roundly attenuated laterally in the anterior part, slightly 

 sinuate in the posterior and carinate, covered with deep, round 

 punctures somewhat irregularly scattered in the discoidal part, 

 separated by smooth intervals, and more closely set on the sides ; 

 scutellum triangular, irnpunctate ; elytra sinuate laterally towards 

 the median part, plainly ampliate in the posterior ; highly costate 

 with the intervals filled with coalescing foveae forming a con- 

 spicuous reticulation, the reticulate foveaa of the fourth, fifth, 

 and sixth intervals are broader or more elongated than the 

 others. 



Allied to S. nataleuse, the elytra are, however, more ampliated 

 laterally behind, but their sculpture is nearly identical ; the apical 

 joints of the antennae are much wider. 



Length 12 mm. ; width 7 mm.

STRONGYLIUM PLAUSIBILE, n. sp. 



Dark blue, with the elytra greenish-bronze ; antennas blue, the 

 five apical joints black, these apical joints are somewhat wide ; 

 eyes broadly separated, surface of head closely yet deeply aciculate ; 

 prothorax covered with round, almost contiguous, well-defined 

 punctures, nearly as much attenuated laterally behind as in front, 

 and carinate ; elytra shaped as in S. auspicatum, and also plainly 

 carinate, but the intervals are filled with series of closely set, 

 deep, transverse punctures separated by narrow walls which do 

 not at all form a reticulation, and thus differ from those of S. 

 natalense and S. auspicatum. 



Length 10^ mm. ; width 4 mm.
