E. Saunders, under the name Pomp ilus (Wesmaelinius) sanguinolentus, 

 F., a ? having been taken in the New Forest by Dr. Sharp on July 18th 

 of that year. Our $ specimen was caught on a Galluna plant at 

 Chobham, on August 11th, and the <$ was swept up on a piece of 

 heathy ground near Woking, on June 21st. Subsequent search has 

 failed to give us any further specimens. 



Mr. Morice sends us the Notes here appended : — 



(1). Characters of Homonotus sanguinolentus, F. ^ . 



Narrow and elongate. Size probably varies. This specimen about as large 

 as normal <J 6" o( P . unicolor, nigerrimus, etc. Length, 7\ mm. 



Dead-black, practically entirely, except the white calcaria. The dull 

 coriaceous surface is clothed with a dense but exceedingly short pubescence of 

 microscopical griseous hairs, sheeny in certain aspects ; apart from this 

 pubescence it seems to be quite hairless. 



The head, viewed from in front, is nearly round. The frons very tumid 

 and slightly shining; the eyes reaching to the base of the mandibles (gense 

 nullx !) and with more or less concave inner margins ; the clypeus very large 

 and prominent, overlapping and hiding mandibles, mouth-parts, etc. ; its apex 

 slightly emarginate. The antennae are stouter than in the $ , their apical 

 joint slightly longer than the others; the basal (scape) short and barrel-shaped, 

 joints 3- — 12 differing little in shape or length ; all more or less convex beneath. 

 Viewed from above the head appears remarkably crescent-shaped, the tempora 

 being produced backwards and brought, as it were, to a sharp point (at any 

 rate to an acute angle) at some distance behind each eye, making the occipital 

 margin as a whole arcuately (or even in some aspects angularly) concave. The 

 occipital truncation is very abrupt (though without any raised margin), and 

 the occiput itself much excavated, overlapping and hiding the narrower extreme 

 apex of the thorax. 



The thorax is widest in the middle (viz., across the insertions of the wings). 

 Its width here is about equal to that of the head. The very long pronotum is 

 trapeziform, widening evenly from its apex to its base. The mesonotum proper 

 is transverse, much shorter than the pronotum. The scutellum is elongate and 

 subtriangular, with a narrow, and sharply excised ("bifid" or " bidenticulate ") 

 apex. The propodeum is of a singular form, each of its sides being compressed 

 and produced posteriorly into a sort of tooth. Viewed laterally, the whole 

 upper outline of the thorax forms one gentle and uninterrupted curve from end 

 to end. The abdomen is flat, or even a little hollowed beneath, strongly convex 

 above. The unguiculi are bifid, i.e., each ends in two branches of unequal 

 length, these branches being sub-parallel to each other, and closely adjacent. 

 (This character can only be seen properly when the claws are viewed laterally, 

 and magnified with a moderately high power of the compound microscope, e.g., 

 a i-inch).
