parallel with the margin ; the elytra are narrower and more pointed at the apex, and 

 have the sides more parallel ; the punctures in the strise on the elytra are evidently 

 finer and closer, and the interstices between the striae are much narrower and more 

 elevated. 



The only British exponents of this species that I have seen are two specimens 

 which occurred to me last year at Killamey. 



H. STBiGiFEONS, Thoms. — A well-marked species, placed by its author at the 

 end of the genus. It has, I think, a facies peculiar to itself. Dr. Thomson distin- 

 guishes it briefly from several widely separated species ; but from its size, colour, 

 and sculpture, it is (I think) incapable of confusion with any British species except 

 eeneipennis and planicollis. From both these species it may be distinguished as 

 follows : — it is, on the average, a little larger (though small examples occur) ; the 

 elytra strike the eye at once as more suddenly and strongly dilated behind the 

 shoulders ; they have, moreover, a broad reflexed margin, the space beyond the last 

 striae being hardly, if at all, narrower than the widest interstice ; the sides of the 

 thorax are much more regidarly rounded ; the longitudinal fovea on the base of 

 the head (which in CBneipennis and planicolUs widens out forwards) is uniformly 

 narrow ; the intermediate sulci on the thorax are less angulated, and the interstices 

 of the elytra are distinctly elevated, the alternate interstices more so than the rest 

 (those between the 2nd and 3rd, and between the 4th and 5th, striae are almost carinate) . 

 I notice also that the maxillai-y palpi are very long and massive. Besides the above 

 distinctions, strigifrons differs from pIa7i{collis in having the punctures in the sti-ise 

 on the elytra much larger and not so close, and the femora of almost unifonu colour. 



This insect appears to be not uncommon in Scotland and Ireland, but I have not 

 seen English specimens. I have no doubt it exists as an enigma in most collections. 



I may, perhaps, be permitted to add that I hope to publish a sketch of the genus 

 llelojjhoriis in my " Outline descriptions of British Coleoptera " in the " Scottish 

 Naturalist " next October.— Thos. Blackbuen, Greenhithe : June, 1876. 



Note on an unrecorded British species of Helophorus. — To the difficulties in 

 this puzzling genus above mentioned, I must add yet another, representing a very 

 marked species certainly not included in those recorded or mentioned by my friend 

 Mr. Blackburn, and several of which have been taken by Dr. Pow-er at or near 

 Woking some years ago. This insect seems, from description, to be not improbably 

 the laticoUis of Thomson: it is readily distinguishable by its thorax being as wide 

 as the elj'tra, convex, with narrow and shallow sulci, of which the two on each side 

 of the middle one are but very slightly Hexuous, and the outer one is parallel to the 

 margin ; by its elytra being not dilated behind the middle, but thence narrowed 

 towards the apex, with very strong, almost crenate, striae, with narrow interstices ; 

 and by the long and sometimes entirely black apical joint of its maxillarj jmlpi. It 

 belongs to the " <c»<?/pe«?iw " group, is IJ lines long, and has bluish-metallic head 

 and thorax, dark brown elytra, and light brown legs. — E. C. Rye, 70, Charlewood 

 Road, Putney, S.W. : June, 1876. 



Notes on some species of Psyllidce. — Psylla visci was described by Curtis in his 

 "British Entomology," vol. xii, p. 565 (1835), where he says that he bred it in the 

 middle of May from larva found on mistletoe at Roiigham (near Bury St. Edmunds.
