592 Descriptive Catalogue [1896. 



Bembidium variegatum, Bohem., 

 Insect. Caffr., i., p. 231. 



Greenish bronze ; palpi infuscate ; the basal joints of antennae 

 reddish, the three following reddish at the base only, the others 

 black or very deeply infuscate ; head smooth ; prothorax as broad 

 as long, cordiform, although slightly angular laterally near the 

 middle, and much narrowed behind, smooth, with the median 

 longitudinal groove and transverse impressions well defined ; elytra, 

 with humeral part straight, one-fourth broader there than the 

 prothorax at its widest part, oblong, little convex, finely but deeply 

 punctato-striate, the striae are six in number on each side, besides 

 the marginal one, the sutural one is curved at apex, and only 

 punctate from the base to the posterior declivity, the other striae 

 barely reach the declivity, and on the third interval are two punc- 

 tures, an ante-median occupying the whole width of the interval, 

 and a post-median one small but distinct ; the colour of the eljiira 

 is olive-green, tessellated with numerous elongated yellowish patches; 

 legs rufescent. Length 4 mm. ; width 1-|- mm. 



Hab. Cape Colony (Cape Town, Stellenbosch, Worcester). 



Bembidium sobkinum, Bohem., 

 Insect. Caffr., i., p. 232. 



Shape, size, and colour of B. variegatum ; the shoulders in the 

 elytra are a little more sloping but not much, and the punctures in 

 the striae are a little less marked ; in the type the elytra are dull 

 greenish bronze, with a narrow apical transverse flavescent band, 

 but I have seen many examples tessellate with pale yeUow as much 

 as in B. variegatum, of which it might prove to be a mere variety. 

 Length 4-4|- mm. ; width If-li mm. 



Hah. Cape (Hope Town, Barkly West, Prieska). 



Bembidium amcenulum. 

 Head and prothorax greenish bronze, turning to dark cyaneous in 

 the centre ; the four basal joints of the antennge flavescent, the other 

 joints and also the apical ones of the palpi infuscate ; head and 

 prothorax smooth, the latter ampliate and rounded laterally, not 

 much constricted at the base, which is as wide as the apex, longi- 

 tudinal groove reaching the base ; elytra elongato-ovate, and owing 

 to the humeral angle being rounded they are not broader at the base 

 than the prothorax at its widest part, little convex, normally striate, 

 the seven striae on each side punctulate and reaching the apex, third 

 interval with two punctures ; the colour is pale yellow with a metallic 

 sheen, and there, is a sutural olive-green band dilated at the base,
