4 Coleoptera. 



13. Stenolophus subcyaneus n. sp. 



Oblongus, supra nigro-piceus, subcyaneo-micans : thorace sub- 

 transverso, basin versus sat fortiter attenuato , angulis anticis et 

 posticis rotundatis. margine pallide testaceo: elytris subcyaneis. 

 parallelis, margine externo lato suturaque apice pallido-testaceis. 

 — Long. 6 mm. 



This species is very similar to St. proximus Dej. and ves- 

 pertinus Panz, but differs distinctly in several essential points. 

 Black on the upper side with a slightly bluish shine, piceous be- 

 neath ; antennae, palps, legs, the margin of the thorax, the exterior 

 striae of the elytra and the apical part of the suture pale-yello- 

 wish; the paler margin of the thorax broader at the base, the 

 two basal pits comparatively shallow, finely punctuated; the 

 elytra parallel, of a slightly bluish shine. The 2 or 3 exterior 

 intervals and the apex pale-yellow. 



Two specimens, both found at the White Nile, one of them 

 at Kaka (21: II). 



14. Poecilus conformis Dej. 



Of this species, which has been previously found in Egj^pt, 

 the collection contains a single male from the White River. 



15. Anchomenus niloticus n. sp. 



fflongatus, nigro-piceus; thorace rotundato, elytris elongato- 

 oblongis, viridi-micantibus, distincte striatis; margine lato. sutura 

 pedibusque rufo-testaceis. — Long. 7 mm. 



A distinct species, very well distinguished from the species 

 known up to date. Elongate, brownish-black, the head compara- 

 tively narrow, smooth, the vertex always with a small pit; the 

 thorax with rounded sides tapering backwards from the middle, 

 black, the anterior- and posterioredges brownish-red, in front and 

 at the back punctuated, with the middle-furrow broad, not rea- 

 ching the anterior- or posteriormargin, the anteriorangles obtuse, 

 the posterior ones rounded; the elytra elongate-oval, of a slight I v 

 shiny green with distinct smooth striae, the 3 or 4 exterior in- 

 tervals and the suture paler, the legs and the coxse brownish- 

 yellow. 



Of this characteristic species, which is somewhat suggestive 

 of A. thoreyi Dej., the collection contains 15 specimens, all col- 

 lected on the White Nile.
