median groove very narrow, sub-median one very narrow in front, bnt more or 

 less broader behind, slightly sinuous, lateral margin faintly yellow in the middle ; 

 the front margin not sinuate behind the eyes, the sides somewhat convergent and 

 straight behind. Sculpture of elytra strong, the interstices broad and almost 

 free from punctuation ; seen from the side the lateral interstices are wide, and 

 the external one very strongly prominent, by which character the species is 

 strongly separated from H. laticollis ; the legs dark yellow inclining to brown, 

 the hind femora not strongly punctured beneath. 



Gu-ildford (Champion), Thornhill (Sharp). If Blackburn's H. strigifrons be, 

 as I suppose, this species, Killarney is also a locality for it. 



This appears to have been first found by myself in 1868, and 

 recently by Mr. Champion, -who sent it to me as H. strigifrons. It 

 seems to be excessively rare. I found only one or two specimens, and by 

 error placed an erroneous number on the one now before me, but I have 

 no doubt the locality is Thornhill. Mr. Champion found some five or 

 six examples ; all appear to be females. 



I may mention that I think it is just possible this may be Rey's 

 original H. crenafus, as I have a faint recollection of having sent a 

 specimen to Pandelle, and Key's original description of crenatus (as 

 will be explained under that head) was made from an English speci- 

 men communicated by Pandelle. 



2. — Heloplwrus strigifrons Thorns. ? 



I have seen only one specimen that I can refer to this species ; it 

 appears to come between H. championi and laticollis; it is smaller and 

 narrower than the former, 3^ by Ih mm., the palpi are rather longer 

 and more slender, the interstices of the elytra rather narrow, the lateral 

 margin less strongly set out, and the flanks less visible from beneath. 

 A different shape of the thorax and a smaller head in addition to the 

 distinct visibility of the flanks of the elytra distinguish it from our 

 British laticollis. 



Pommeru, Goeslin, Lvillwitz (in coll. Champion). 



Whether this species is really the strigifrons of Thomson is 

 doxibtful. Thomson described it from a single example, and great 

 doubt has always prevailed as to it. In any case it is no doubt near 

 this German example, but he says of strigifrons : " Prothorax apice 

 fere trisinuato," which does not apply to any member of this group 

 known to me. T^he species mentioned as British by Blackburn (Ent. 

 Mo. Mag., xiii, p. 40) is, I think, not this, as I have stated under 

 H. chamjnoni.
