476 Mr. G. R. Waterhouse's Notes on 



or nearly so. Head nearly round and convex ; the eye but little 

 prominent, the surface very delicately and rather sparingly punc- 

 tured. Thorax distinctly narrower than the elytra, moderately 

 transverse, pretty thickly and distinctly punctured ; and, besides 

 the ordinary pubescence, with three or four setae on each side. 

 Elytra about one-fourth longer than the thorax ; finely and thickly 

 punctured. Abdomen slightly dilated in the middle, with the 

 basal joints pretty thickly and distinctly punctured ; the 5th and 

 6th joints nearly smooth. The head and thorax are black, with an 

 indistinct aeneous tint ; the elytra are brown, with the outer margin 

 dusky: the abdomen black. The legs fusco-testaceous, with the 

 femora rather darker than other parts ; they are distinctly pu- 

 bescent, and the tibiae are furnished with setae: one, at least, of 

 these longer hairs may be seen on the intermediate tibias, and two 

 on the posterior tibiae. The species most nearly resembles H. 

 marcida, but is a trifle smaller : he thorax is rather shorter, has 

 the sides less rounded, and not contracted behind ; the elytra are 

 less ample, and rather more finely punctured. The antennae in 

 both sexes closely resemble those of the female of H. marcida, 

 excepting that the basal joints are dark instead of being pale. 

 The male of fJ. marcida* is remarkable for having the third joint 

 of the antennae somewhat inflated, and with a width fully equal to, 

 if not exceeding, that of any of the following joints ; the two basal 

 joints are somewhat stouter than the corresponding joints of the 

 female, and so are the fourth and fifth joints. I can perceive 

 scarcely any sexual distinction in the penultimate abdominal seg- 

 ment of this species. In H. l(svana, a male specimen, from Dr. 

 Kraatz, has the upper plate of the penultimate segment truncate 

 at the apex, and with three very gentle emarginations (of which 

 the central one is the broadest) separated by very small obtuse 

 teeth. 



I have seen but two English specimens of H. Icevana ; they 

 were both found by Dr. Power — one specimen in Highgate Wood, 

 the other at the Holt Forest.

 The insect exhibited is a trifle smaller and relatively narrower 

 than the H. nigritula, and has the antennae shorter and stouter. 



* In the males of some other species the 3rd joint of the antennae is somewhat 

 incrassated. In H. nigricomis (^fungicnla, Thorns.), for example, this distinc- 

 tion is evident. In FI. marcida the sex with the more slender antennae is regaided 

 as the n:ale by Dr. Kraatz.
