322 Mr. A. Murray on Coleoptera from Old Calabar. 
minusve nigro; scutello pallido; elytris singulis margine 
testaceo circumcinctis ; pedibus pallidis. 
Long. 34 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 punctate, and bearing faint traces of two or more 
cost. 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 bimyzxata, or “with two wicks,” in 
allusion to there being only two phosphorescent segments of the 
abdomen.
