COLEOPTERA 145 



and sixth interstices of tlie elytra are more or less raised and bear fine setae, but the 

 elevations are feeble. The other interstices are quite distinct. The elytra themselves 

 are decidedly shorter than in D. insignoides, the rostrum in the $ is more finely and less 

 rugosely punctured than in that species. In a strict dorsal aspect of the elytra the 

 acute 8th interstice always forms a portion of their lateral outline near the base.

(16) Dryophthorus fuscescens, sp. nov. 



Haud latus, statura minore, fuscescens. Oculi minimi. Pronotum antice fortiter 

 constrictum, grossius punctatum. Elytra seriatim grossius punctata, interstitiis cunctis 

 sat distinctis, secundo quartoque inaequaliter distincte carinato-elevatulis, cumque 

 sexto, setis brevissimis vestitis. Long. 3 '5 mm. 



A small and very distinct species, with unusually small eyes, which consist of 

 comparatively few coarse facets. The rostrum of the % is closely, coarsely and rugosely 

 punctured between the smooth ape.x and the line of insertion of the antennae, and is 

 hardly shining. In the ^ the sculpture of the rostrum is entirely concealed, and this 

 may possibly be the case with the % when alive, but the covering is removed in the 

 single example of this sex.

(17) Dj-yophthorus verticalis, sp. nov. 



Piceus, subrobustus. Rostri (?) pars praeantennalis nitida, fortiter distincte punc- 

 tata. Oculi sat magni. Pronotum grossius punctatum, antice fortiter constrictum. 

 Elytra seriatim grosse punctata, interstitiis sat distinctis, secundo quartoque inaequaliter 

 elevatis et setulosis, postice fortissime declivia, fere verticalia. Long, (rostr. excl.) 

 3 — vix 4 mm. (Plate VIL fig. 20.) 



The male of this species is at once distinguished from any other of the section by 

 its short robust form as seen in dorsal view, the elytra becoming wider at the base of 

 the posterior declivity than they are across the shoulders. Posteriorly they are strongly 

 vertical and of slightly recurved form. The female is less remarkable but it is more 

 robust and larger than the allied species. The rostrum is shining and strongly punc- 

 tured. In both sexes the sinuation of the 6th interstice of the elytra causes the 8th 

 to be distinctly visible in dorsal aspect, so that it evidently forms part of the lateral 

 outline. The second and fourth interstices are unevenly raised, or carinate, and 

 setulose.
