minusve nigro ; scutello pallido ; elytris singulis margine 

 testaceo circumcinctis ; pedibus pallidis. 

 Long. 3^ lin., lat. 1 lin. 



Pale dirty testaceous brown ; females pubescent both above 

 and below ; males pubescent below. Head black, punctate. 

 Eyes in the male very large and prominent, in the female small 

 and level with the head. Thorax testaceous, with a larger or 

 smaller black space in the middle and towards the anterior mar- 

 gin ; strongly punctate ; transverse ; anterior margin projecting 

 in the middle ; sides parallel and nearly straight ; anterior 

 angles rounded; base bisinuate, posterior angles projecting 

 and nearly right-angled ; the sides slightly reflexed ; the base 

 (except the angles) transversely bisinuately impressed close to 

 the margin, and with a rounded depression on each side, just 

 within the projecting angles. Scutellum large, elongate, trun- 

 cate at the apex, widest at the base, pale. Elytra with a pale 

 margin running round each from the shoulder to the suture ; 

 irregularly puiictate, and bearing faint traces of two or more 

 costse. Underside finely punctate ; the thorax and margins of 

 the metathorax pale testaceous. In both sexes the last two 

 segments of the abdomen are alone phosphorescent, and nearly 

 white and impunctate ; pygidial segment rounded triangular. 



Apparently rather rare. 



From both sexes having only two segments of the abdomen 

 phosphorescent, the species should belong to one or other of 

 Motschoulsky's subgenera Delopyrus and Delopleurus (both also 

 from Africa, and each represented hitherto by only one species, 

 the former from South Africa, the latter from Mozambique), that 

 being the main character of these sections. M. de Motschoulsky 

 gives characters for distinguishing them between themselves 

 founded on the form of the thorax and pygidium. This species 

 comes between the two as regards the thorax, it being neither 

 in the form of a crescent nor a transverse square (which are the 

 respective characters of that part given by Motschoulsky), it 

 being indeed somewhat rounded in front, but subquadrate 

 behind. In regard to the pygidium it corresponds with Delo- 

 pyrus. If it must go to either one or the other, that subgenus 

 seems therefore to have the stronger claim to it. 



I have called the species himyxata, or " with two wicks," in 

 allusion to there being only two phosphorescent segments of the 

 abdomen.
