Joints 6 and 7 of the antennas white, black above ; the scape 

 brownish below. Face closely punctured, bare ; the sides of the 

 raised central part, its apex and the sides of the clypeus black, the 

 black lines united together, the rest yellow. Mandibles black, the 

 basal half yelloAv, edged with black. Palpi yellow ; the apical joint 

 of maxillary fulvous. Front smooth and shining ; the vertex irregu- 

 larly closely, strongly and somewhat ol)liquely striated and slightly 

 depressed before the ocelli. Mesonotum closely and strongly acien- 

 lated. Base of the metanotum closely, irregularly striated, most 

 strongly on the outer-side ; in the centre are two keels ; the only 

 transverse keel is curved Ijackwax'ds in the centre ; the rest of the 

 segment is closely, irregularly reticulated ; at the apex, in the middle, 

 is a smooth space with three longitudinal keels. Propleura^ for the 

 most part strongly longitudinally striated ; at the top is a stout 

 oblique keel. Mesopleuraj finely rugosely punctured at the base 

 and top, the punctures running into stri.-e. The base of the meta- 

 pleurie on the lower part depressed, stoutly crenulated, the lower 

 and apex strongly obliquely striated, the striaj running into reticu-

MeSOSTENUS VERSATILIS, sp. nOV. 



Length 15 ; terebra 4 mm. 



Agrees closely in coloration and form with M. retlcnlatus and 

 in having the median segment reticulated ; but may be known by 

 the shorter hinder coxa^, which are also devoid of black, by the 

 blackish hinder trochanters and by the longer and thinner spines 

 on the metathorax. 



Antennae stout, broadly annulated with yellow in the middle. 

 Black : the face, clypeus, base of mandibles, palpi, the inner eye orbits, 

 an elongated line on the base of the pronotum, gradually narrowed 

 towards the apex, tegulse, tubercles, scutellar keels, scutellum, a 

 crescent-shaped mark behind the posterior wings, the sides of the 

 obliquely sloped apex of the median segment, its spines, about the 

 apical fourth of the basal three abdominal segments, the middle 

 more narrowly and the apical entirely, yellow. Legs rufous, the 

 extreme apex of the hinder coxse, more or less of the hinder tro- 

 chanters, the apex of the hinder femora, tlie base of the hinder tibia? 

 more narrowly and their apex more broadly, black. Wings hyaline,
