uiarg-in stands out less ; the sculpture of the median and sub-median intervals 

 is usually a fine punctuation, but varies a good deal ; the antennae, legs, and 

 palpi are bright yellow, slightly infuscate at the tips, the tarsi broadly darker 

 terminally. The series of punctm-es of the elytra are fine, the interstices broad 

 and flat. The aedeagus (fig. 55 ; and from photograph, on p. 236, Vol. LI) is 

 highly perfected ; the lateral lobes are slender, about as long as the basal 

 piece ; the struts of the median lobe are short, the barrel long, aboiit as long as 

 the struts, the chitinisation at the junction of the struts with the barrel is 

 very strong.

H. offinis is considered to be a rare inseect, and that is my 

 experience of it in Britain. Owing however, to the difficulty of dis- 

 tinguishing it from the allied forms, records of its distribution are 

 not trustworthy. 



Erich sou's description of H. dorsal if^ was probably taken from 

 this species and H. dijjinis, and is correctly placed in Zaitzev's cata- 

 logue as a synonym. H. ericluoni Bach, is merely a catalogue name 

 proposed to replace dorsaUs Er., and falls with that name as a 

 synonym of affinis.

I have seen only one example of this species, but it is a male, and the 

 aedeagus marks it as allied to dijjinis and minutus, from both of wliicli it is 

 easily distingviished. The margin of the thorax is only very finely set out, and 

 the front angles are not at all prominent. The palpi are rather largely 

 developed, the apical joint being indefinitely darker on its distal half. The legs 

 are rather long and stout, and the wliole facies reminds one of the mulsanti 

 group. The aedeagus (fig. 56) is nearest to that of dijffinis, the basal piece 

 being elongate, longer than the distal segment, the median lobe is short, but 

 the struts are rather long, the barrel being quite short. 



Received from Dr. Sahlberg many years ago, without name. It 

 may be perhaps found in some collections under affinis, but it has 

 quite a different facies, and the aedeagus separates the two completely.
