between them, and Ph. velatus has the aquatic character much more decided. 

 This species has been already given as Irish by Mr. Wollaston (" Zoologist," 1847, 

 p. 1573); but it would appear from the " Entomologists' Annual," p. 105, that 

 Ph. velaris was the insect intended, which belongs to another section of the genus, 

 having the ordinary structure of tarsi, felted beneath, and with bilobed penultimate 

 joint. Three other Irish species were shown, canaliculatus (taken at Blarney), quad- 

 rituberculatus, and comari (both at Holywood). The larvte of two of this section 

 have been described viz., of P. notula by Ferris in the " Memoirs of the Academy of 

 Lyons," and of P. velaris by Dufour in the " Annals of the French Entom. Society ;" 

 but that of Litodactylus is as yet unknown. Another insect of the same family, 

 not found by Mr. Clear, Gymnetron beccabungoe, was taken (a single specimen) in 

 the glen of the Shournagh river. This and the neighbouring streams which swell 

 the current of the Lea, afforded Orectochilus villosus more abundantly than it had 

 been found elsewhere. But, in consequence of its nocturnal habits, it is only to be 

 procured by day under stones, or by fishing along the shaded edges of the stream. 

 At Blarney Lake Gyrinus celox (Schicedte) occurred very sparingly. It is to be 

 observed that this is reduced by Schaum (Catal. Hydradephaga Brit. Museum) to 

 a synonym of G. bicolor, which last has been found by Mr. Furlong in Kerry. Of 

 the genus Cassida the Irish list is very scanty, especially as regards the Dublin 

 district, within which only C. rubiginosa is vouched for. The European list in 

 the Stettin Catalogue amounts to 31, increased to 40 in Gaubil's, of which, how- 

 ever, two are properly Algirian, and two Caucasian. Even the British list in 

 Curtis's Guide amounts to 18. Besides the species named, C. equestris is not 

 uncommon in other parts, chiefly on Menthce in watery places. C. nobilis has 

 occurred on Cochlearia by the shore of Strangford Lough. Mr. Clear, by letter, 

 had supplied the names of two more, obsoleta and hemisphcerica, the correctness of 

 which has been ascertained by a late reference to the relics of his collection ; and 

 of the former, Mr. Haliday procured two specimens in the neighbourhood of Cork. 

 The genus Colon numbers five species in Ireland, none of which have been 

 observed in the Dublin district, though C. brunneus, which has occurred in Cork, 

 Gal way, and Wicklow, as well as in the North of Ireland, may be looked for here 

 also. The other species recorded are serripes, appendiculatus, calcaratus, and 

 dentipes (Sahlberg). This last had been given as a new species (C. spinipes) by 

 Mr. Haliday in the " Entomologist ;" but Kraatz has since shown that the insect 

 there described is the true dentipes of Sahlberg, and that Erichson has a different 

 species under that name. It is not yet determined which of these two is the 

 dentipes of Murray's Catalogue of Scotch Coleoptera. The enumeration of new 

 species in the " Entomologists' Annual" suggests some notes on species already 

 recorded as Irish. Gymnusa brevicollis, given as such by Mr. Haliday in the 

 " Entomologist" (1841), should be G. variegata, Kiesenwetter, as Dr. Schaum sub- 

 sequently showed him. Boreaphilus brevicollis, described in the same place, 

 judging from the figure given by Spry, is probably identical with Coryphium 

 angusticolle, Stephens ; but the characters were entirely misapprehended by him, 

 and Sahlberg's older generic name cannot justly be made to yield. The genus 

 is now rich in synonyms, Heer having more lately characterized it as Chevrieria, 

 and last of all the name Macropalpus has been given it in the "Annals of the French 

 Entom. Society." Stephens's trivial name is unfortunately chosen ; the thorax in 

 this species being much broader in proportion than in the type B. henningianus^ 

 also shown. The only English specimen of the former is believed to be that in 

 Mr. Kirby's collection. Three have been found at Holywood. One was taken on 

 a rotten stump, the others off grass in sweeping. Arpedium brachypterum was first 

 recorded as British in 1851 (Hardy and Bold's Catalogue of Coleoptera, &c.) ; 

 but Irish specimens, with name and locality (Sliebh Donard), have been in the 

 British Museum collection since 1847. These appear to agree very well with the 

 form described by Kiesenwetter as A. troglodytes. It has not yet been found on 

 any of the other mountains of Ireland. The other native species of the genus, 

 A. myops, Hal., "Entomologist" (1841), has been definitely pronounced by 

 Kraatz to be identical (as there queried) with A. humile, Erichson. The habitat 

 given by him, Ural Mountains, and his having overlooked a character so singular 

 in this tribe, as the want of ocelli, forbade its positive identification, before, with a
