from South and West Africa. 91 



plain prostemum, as well as the much more dilated tibire, 

 from the latter the quite finely facetted eyes and superior 

 size, amply separate it, not to mention minor differences such 

 as the antennal and palpal structure. 



Pycnogeusteria Kraatzi, sp. n. 



Oblonga, subparallela, aterrima, uitida, crebre fortiter punctata ; 

 elytris seriatim punctatis, striis parum impressis, iiiterstitiis 

 crobre minute punctulatis ; labro, antennis (apice fusco), palpis, 

 prothoracis, epimeris, metasterno pcdibusipie la^te luteis ; corpore 

 subtus leviter crebre punctato. 



Long. 9 millim. 



Hab. W. Africa^ N. Cameroon, Johann Albrechtshohe 

 (L. Conradt). 



Head black, strongly, at the base almost coarsely, punctate j 

 the epistoma very distinctly separated from the labrum, pro- 

 duced and deflexed, the latter brig-ht pale yellow; the mouth 

 and trophi yellow, except the mandibles, which are only 

 pitchy externally. Thorax black at the base, twice as wide 

 as long, narrowed in front, with the front angles a little 

 depressed, finely margined except in the middle of the front 

 and base, thickly punctured, but less so than the head, and 

 not so strongly, there being room for other punctures. The 

 base of the elytra is of the width and forms an even outline 

 with the thorax. The elytra are entirely black, very finely 

 seriate punctate, the small punctures in the series being close 

 but not iujpressed in stria?, the interstices being also thickly 

 minutely punctate ; they are continued evenly to the end, 

 but coalesce before reaching the apex. The body beneath is 

 sparsely and finely punctured ; the mesosternum is black (or 

 pitchy in less matured specitnens) ; the metasternum with its 

 side pieces, the meso-episterna, and abdomen and legs are all 

 entirely clear luteous yellow. 



I have pleasure in dedicating this insect to Dr. Kraatz, the 

 veteran writer on European Goleoptera, who sent it me with 

 other Erotylidee, 



N.B. — This insect very closely resembles a \\q\\ ZytJionia, 

 which I propose to describe as Z. anthracina^ and which 

 appears to inhabit the same district, as well as the Congo, 

 from whence my examples came.
