190 RHYNCHOPHORA. 
1. Dryoceetes limbatus, sp. n. 
Cylindricus, subelongatus, subnitidus, nigro-piceus, prothoracis apice et elytris, limbo marginali excepto, 
subluteo-testaceis, pilis pallidis tenuibus aspersus; prothorace elliptico, anterius tantum subconstricto, 
granulato, linea media basali levi; elytris striato-punctatis, interstitiis rarius uniseriatim punctatis, apice 
fortiter convexe declivi, utrinque preter suturam deplanato, obsolete punctato. 
Fem. Fronte dense villosa. 
Length 2°1—2-4 millim. 
Cylindric, rather elongate, subnitid, with moderately close and long pubescence of fine pale hairs. Head 
black, ( $ ) impressed over the mouth, thinly hairy and weakly punctured, more strongly at the apex and 
sides ; (@) with close erect villous pubescence: eyes oval, deeply emarginate; antenne testaceous, the 
club rounded, with slightly curved sutures. Prothorax longer than broad, subelliptic, usually with a 
constriction at its anterior third, widest behind the middle, the sides curved throughout, the apex 
obtusely rounded, the hind angles widely rounded, the base bisinuate; surface black, with the apical 
third luteo-testaceous, thinly pubescent, more closely towards the apex, granulate, with a median smooth 
line from the base to before the middle. Scutellum minute, obtuse triangular, black. Elytra wider at: 
the base than the prothorax and two-thirds longer, their basal margins curved, the humeral angles 
rounded rectangular, callose, the callosity not shining, the sides gently curved throughout, slightly 
narrowed before the apex, which is truncate, its lateral angles rounded; surface cylindric, strongly and 
obliquely declivous for the posterior fourth, luteo-testaceous, the lateral borders and sometimes a scutellar 
patch and the suture black, with fine suberect pubescence, closer on the declivity, striato-punctate, the 
strive shallow, the sutural stria scarcely deeper, their punctures strong and close, weaker towards the 
sides, interstices narrow, flat, transversely rugulose, especially towards the base, with single rows of 
punctures a little finer and about half as frequent as those of the strie; declivity flattened on each side 
of the suture, which is narrowly elevated, shining, obsoletely lineato-punctate. Underside black, 
pubescent. Legs piceous.

Four specimens. The species is about the size of Dryocetes alni (Georg), but more 
attenuated, with the punctures of the elytral strie and interstices much stronger. I 
follow Kichhoff (Die eur. Borkenk. p. 218) and Hopkins in regarding the forms with 
a villous forehead as the female. 
2. Dryocetes macilentus, sp. n. 
Angustus, cylindricus, subnitidus, niger, pedibus piceis, griseo-pilosus ; prothorace elliptico, granulato, linea 
media apicem fere attingente levi; elytris lineato-punctatis, stria suturali solum subimpressa, interstitiis 
subeequaliter uniseriatim punctatis, subrugosis, apice fortiter declivi, deplanato, subtilius punctato. 
Long. 2°3 millim. 
Cylindric, elongate and narrow, subnitid, black, with suberect grey pubescence. Head subconvex in front, 
rugosely punctured at the sides, and thinly hairy, shining towards the middle, with a short supraoral 
carina, aud a shallow impression above; antenn testaceous-brown, the club rounded, with curved 
fringed sutures. Prothorax elliptic, longer than broad, widest at the basal third, the sides regularly 
curved, the apex obtusely rounded, the hind angles obtuse, the base truncate ; surface thinly pubescent, 
covered with small granular asperities, their interspaces subreticulate, with a median smooth line 
traceable from the base almost to the apex. Scutellum small, obtusely triangular, convex, shining. 
Elytra nearly twice as long as the prothorax, not wider at the base than its greatest width, the basal 
borders subconvex, humeral angles subrectangular, callose and shining, sides parallel, apex very obtusely 
rounded ; surface cylindric, strongly declivous and rounded apically, lineato-punctate, the sutural stria 
alone subimpressed, the punctures rather strong, in regular rows, bearing short decumbent hairs, interstices 
narrow, subrugose, as strongly though less closely punctured, with longer suberect hairs; declivity very
