SCOLYTID^. 199 



II. Smaller and more glabrous above, 

 the prothorax a little more trans- 

 verse, the elytral interstices regu- 

 larly uniseriate-punctate, the punc- 

 tures each bearing a short, fine, 

 decumbent, whitish hair . . B. T.-album, L. 



( = ATRiPLicis^ Steph., 



martulus, Sahib.) 



B. pilistriata has been taken in various southern localities, Sheppey, 

 Faversham, Arundel, Woking, Wicken, &c. According to Bedel, 

 both forms are sometimes found together in France, but in Algeria 

 only B. pilistriata occurs. All the Irish records for B. T.-album 

 appear to refer to B. pilistriata (Halbert), Irish Nat. 1910, p. 33. 



SCOLYTID^. 



HYPOTHENEMUS, Westwood. 



This genus, formed by Westwood to include the very small Scolytid 

 beetle, Hyjyothenemus eruditus, was described and figured by him as 

 having a three-jointed funiculus to the antennse. Mr. W. J. H. Bland- 

 ford, who has recorded the beetle from Central America, published in 

 li)04 that there are four joints in the funiculus. Mr. E. A. Newbery 

 thus describes the antennse as viewed from the vipper side (Enb. Mo. Mag. 

 xlvi. {2 Ser. xxi.), 1910, 83) : " First joint (scape) elongate. Funiculus 

 with four joints, of which the first is cup-shaped, broadest at the apex 

 and rather broader than the scape, very little longer than broad : the 

 three following joints very minute, two rather transverse, three and 

 four increasing in width and decreasing in length, the fourth being a 

 flat plate adpressed to the club. The club is large, flattened, and 

 4-jointed, with the sutures curved on the upper side, but nearly 

 straight beneath. 



Mr. 0. E. Janson has found the insect in the " Brazil nut " of 

 commerce, and in the cover of a book from Java. Dr. Sharp has bred 

 it from the cover of a book from Singapore. The insect is exotic, and 

 ought not to be included in our lists. 



PITYOGENES, Bedel. 

 P. trepanatus, Noerdl. (Stett. Ent. Zeit., 184<S, 239) ; elongatus, 



Lowendal (Tom. Danm. 1881), Gl). Closely allied to P. chalcograp/ms, 

 L., and resembling that species in having three teeth of about the same 

 size on each side of the apical impression of the elytra, placed at an 

 equal distance apart. It is, however, a larger insect, and the elytra are 

 longer in proportion to the thorax, and are much moi-e distinctly 

 punctured, the punctures being arranged in well-marked regular rows
