Scolytidee from Africa. 321 



appears to be identical with the typical one, though some 

 specimens show slight differences in the tuberculation and 

 punctuation of the elytral apex. However, the curious 

 disparity in size between the sexes, which appears to be 

 constant in the Ternate and Celebes examples, is not main- 

 tained, as the one male and ten females I possess all range 

 from about 8 to 9 '5 millirn. 



Ethadopselaphus, gen. nov.* 



Dactylipalpo affinis ; discedens palpis maxillaribus brevibus, tri- 

 articulatis. 



This genus differs from the preceding in the fact that the 

 maxillary palpi are short and three-jointed, the two basal 

 joints being cylindrical, the first transverse, the second rather 

 longer, the apical joint shorter and conical. The labial palpi 

 are not quite so elongate as in Dactylipalpus, but are two- 

 jointed, and the structural characters are in other respects 

 identical, the characteristic thoracic striga being present in 

 the females. 



Inconvenient as it is to separate a genus on such a point 

 of structure, it is one too important to be disregarded, and 

 fortunately, owing to the large size of the species, the 

 maxillary palpi can, with a little trouble, be examined 

 without dissection. The two-jointed condition of one or both 

 pairs separates this and the preceding genus from other 

 Scolytinae ; and it is noticeable that, though in the three- 

 jointed maxillary palpus Ethadopselaphus forms a link 

 between Phloeoborus and Dactylipalpus, its two species, both 

 African, have a peculiar elytral sculpture, and do not 

 resemble each other or any species of the allied genera. 



E. cicatricosus, which I have more thoroughly examined, 

 may be regarded as the type. 



1. Ethadopselaphus cicatricosus, sp. n. 



Oblongus, opacus, niger, pilis brevibus, appressis, cinereo-flavis 

 ornatus ; elytris irregulariter punctato-sulcatis, sulcis sinuatis, ad 

 apicem solum profundis, 4° cum 5°, dein cum 3° connexo, inter- 

 stitiis rugosis, rlavo-pilosis, 3° ter, 5° bis, 7° semel in disco callose 

 ampliatis. 



Long. 8-11 mm. 



cJ . Fronte subimpressa ; prothorace absque striga transversal!. 



Oblong, dull black, pilose, with short decumbent brownish- 

 yellow hairs. Head shining, strongly punctured in front, with
