54 Descriptive Catalogue [1897. 



much transverse, eleventh briefly ovate and obtusely acuminate ; 

 prothorax of nearly the same width as the head, subcordate, more 

 atteiiuate behind than in front, obtusely dentate laterally, beyond 

 the median part and alongside a large lateral fovea, median fovea 

 small, transverse sulcus angular, discoidal fovea free, deep, rounded, 

 base bifoveate ; elytra elongate v^ith the shoulders quadrate, not 

 attenuate at base, sides slightly rounded towards the median part, 

 basal part with two large fovese, dorsal stria more or less abbreviated 

 and situated at about one-third of the width ; first three dorsal seg- 

 ments of abdomen short, the two basal ones impressed transversely 

 in the middle of the basal part, fourth twice as long ; metasternum 

 sulcate ; tibiae slightly thickened externally beyond the median 

 pai't. 



Male : Fourth, fifth, and sixth ventral segments impressed trans- 

 versely, seventh large, strongly triangular at apex, and having a 

 longitudinal, entire, and slightly arcuate carinule. 



Female : Sixth and last ventral segment large, acuininate at tip, 

 last dorsal one very small and acutely dentate at tip. Length 

 1-40 mm. 



This species is closely allied to E. africanus, Eaffr., from Zanzibar 

 and Abyssinia, and is to be distinguished by sexual characters only ; 

 in E. africanus male the ventral segments have no impression, the 

 seventh is smaller and more rounded ; in the female the last ventral 

 segment is rounded and the last dorsal one not dentate. 



Hab. Rhodesia (Salisbury). 



EUPLECTUS QUADEICEPS. 



Very similar to the preceding species ; differs in the shape of 

 the head, which is not at all narrowed in the anterior part, and is 

 thus nearly square ; the antennae are thicker, the tenth joint not so 

 transverse, and the last one is more elongate, nearly straight laterally 

 and is rounded at tip. 



The sexual differences are very marked in the male, the fourth 

 ventral segment of which is obtusely angular and projects a little 

 over the following one, which is deeply and transversely impressed 

 under the apical angular edge of the fourth, the sixth is impressed 

 in the centre, and the seventh bears only at tip a small elongate 

 tubercle ; in the female the last dorsal segment has no tooth, and 

 the last joint of the antennae is quadrate. 



Hah. Ehodesia (Salisbury). 



E. africanus from Zanzibar and Abyssinia, E. discoidalis and E. 

 quadriceps from South Africa, are so closely allied to one another 

 that they might be taken for one and the same species but for the
