270 [October, 



and I consider that most of tlie descriptions of " dorsalis " of foreign 

 autliors do not refer to mulsantl at all. Specimens in the Laferte 

 collection named dorsalis by Mulsaut are quite a different species ; 

 Bedel's description of mvlsanti in Faune Col. Seine is probably correct, 

 though in the catalogue he gave fulgidicollis Motsch. as a synonym, 

 that being, however, a distinct species. Finally, I may remark that 

 Sahlberg's original description of H. borealis applies well to nndsanti, 

 and that I shall not be surprised if it prove to belong to our British 

 species, which would then take the name of horeaUs ; quadricoUis 

 being in that case applicable to the species I have designated as 

 borealis. 



11. — Helophorus sp. ? 



Among the specimens of H. mulsanti found by me at Dumfries, 

 is one that is so peculiar that I should not hesitate to treat it as 

 distinct were it not unique. It is of elongate form nearly 5 mm. long, 

 with large thorax, and very peculiar mentum, which is dull, rugose, 

 and prominent, the broad reflexed sides rising steeply from the middle ; 

 the terminal joint of the labial palpus is perhaps rather more slender 

 than in mulsanti. This specimen may be a remarkable aberration. 

 It greatly resembles borealis var. quadricoUis, but the trophi are d liferent. 

 I unfortunately selected this specimen for dissection when I com- 

 menced my examination of midsanti, on account of its large size, so 

 that it is now in fragments. 



12. — H. oblitus sp. n. 



Supra pallidus, capite aurato, prothorace rufescente, medio sub-metallico, 

 elytris testaceis panmi nigro-maculatis, fortiter punctato-striatis, interstitiis sat 

 convexis, subtus niger, antennis 2^0'lpis pedihusque fiavis. Long. 3^ mm. 



This appears to be a distinct species connecting mulsanti and 

 affinis. It should not be difficult of recognition on account of the 

 unusually great visibility of the flanks of the elytra on the under- 

 surface. 



Maxillary palpi elongate as in tnulsanti, last joint of labial rather small as 

 in 'mulsanti. Head moderately coarsely sculptured, channel of vertex open in 

 front. Thorax shorter than in mulsanti, front margin rather deeply emargi- 

 nate behind the eye, front angle therefore appearing prominent, grooves much 

 as in m,ulsanti, sculpture much as in mulsanti ; sculpture of elytra much as in 

 mulsanti, though haidly as deep and coarse. On the imder-surface the flanks 

 of the elytra stand out very distinctly outside the epipleura, more so than in 

 mulsanti ; the abdomen reddish towards the extremity.
