by Haliday of B. henningianns in the Entomologist, Vol. I, p. 187, as 

 follows : " Bor. hcnningianus. Aptcrus, thorace oblongo capita an- 

 gustiore et elytris thorace parum longioribus fortiter punctatis." 



Niphctodcs was described by Miller (Verh. zool.-bot. Ges. Wien, 

 XVIII, 1868, p. 16), and made a subgenus of Boreaphilus by Gangl- 

 bauer. (Kaf. v. Mittleu., II, p. 700.) The genus was subsequently 

 recognized as valid by Ganglbauer. (Ann. Nat. Hofmus. Wien, II, 

 1896, p. 174.) The species placed in this genus are said to be wing- 

 less; a fact which has not been verified from lack of material. It has 

 been ascertained that in Niphetodes deubeli Gangl. the elytra are 

 solidly anchylosed, which is not the case in B. hcnningianus. 



Miller's description of Niphetodes is as follows: 



" Mandibulje tenues, falcatae, medio dente longiore armatse. 



" Maxillae malis elongatus, mala interiore intus apice ciliata. 



" Palpi maxillares articulo tertio tumido, quarto minimo, subulato. 



" Palpi labiales articulo primo secundo duplo longiore. 



" Prothorax lateribus rotundatus. 



" Elytra prothdracis longitudine ; alse desunt. 



" Tibiae muticre, tarsi articulis quatuor primis longitudine sub- 

 aequalibus." 



To which may be added, as Ganglbauer states, that the ocelli are 

 lacking, a fact which distinguishes the species from the rest of the 

 Omaliini. 



An examination of specimens of A'', deubeli Gangl. and N. eppel- 

 sheimi Gangl. shows that the thorax of deubeli is like that of Borea- 

 philus henningianus, and that of eppelsheimi is like that of Coryphiiim 

 angusticolle, being more or less cordate. It is, however, slightly nar- 

 rower than the head. B. deubeli is placed in a subgenus Hypsono- 

 thrus by Ganglbauer, 



The genus Ephelinus Cock (EpJielis Fauv.) is of interest as con- 

 taining three species described by LeConte, placed originally by him 

 in Coryphium. (Lee. New Sp. Col., I, 1863, p. 57.) The only struc- 

 tural character given by him is that of the shape of the thorax, thus : 

 (i) pallidum, "thorace latitudine baud breviore, postice parum an- 

 gustato lateribus serrulatis." (2) gutfatum, "thorace latitudine baud 

 breviore, postice modice angustato, lateribus obsolete serrulatis, callo 

 dorsali pone medium laevi." (3) notatum, "thorace latitudine baud 

 breviore, postice paulo angustato, lateribus serrulatis, callo postico 

 dorsali."
