middle; it is smooth and shining; and imp^^nctate, with 

 lateral margins broad and tnnied outwards as well as 

 upwards. The legs are yellowish ; the basal joint of the 

 posterior tarsus about as long as the three following together. 

 In the male the 2nd segment is armed in the middle with a 

 long sharp spine, about as long as the segment itself; the 

 lateral margins of the segments are detached and acumi- 

 nated behind, but not produced into spines (as they are in 

 M. scabripenn'ts) ; the 6th segment is furnished with a 

 longitudinal plica on each side, and has two tubercles a 

 little before the hind margin. The 7th segment is 

 thickly covered Avith rather fine granulations, and has a 

 larger tubercle on the middle ; its hind margin is obscurely 

 serrated and has a shallow notch in the middle. In the 

 female the 2nd segment is simple and the tubercle of the 

 7th segment is absent. 



Ega; three individuals, — two male, one female.

AntennjE rather long, moderately stout, the four basal 

 joints yellowish, the rest infuscated; 3rd joint twice as 

 long as the 2nd ; 4th intermediate in length between the 

 2nd and 3rd ; 5th much shorter than the 4th, rather longer 

 than broad ; 5 — 10 differing but little in length, each 

 slightly stouter than its predecessor; 11th rather stouter 

 than the 10th, but not quite so long. Head blackish, 

 shining, very coarsely punctured. Thorax yellowish, about 

 as long as broad, slightly narrowed behind, very coarsely 

 punctured, obsoletely depressed on each side the disc. The 

 elytra yellowish, infuscate about the apical angle, scarcely 

 so long as the thorax but much broader, closely and mode- 

 rately finely punctured. The liind body is yellowish, the 

 segments irregularly marked Avith a pitchy colour ; before 

 the apex nearly entirely pitchy ; smooth, shining and im- 

 punctate above ; distinctli/ and moderately closely punc- 

 tured beneath. Legs pale yellow, Avith the basal joint of 

 the hind tarsus rather longer than the three next together. 



In this species the sculpture of the elytra consists of 

 true impressions closely packed, so that the interstices 

 appear like rough irregidarly Avaved lines. 



Ega ; one female individual.
