iniddle; it is smootli and sliinino- and impnnctate, with 

 lateral niarc;ins broad and turned outwards as well as 

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

 ])Osterior tarsus about as long as thethi'ee following together. 

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

 long shall? 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 

 31. scabripcmiis) \ the Gth segment is furnished with a 

 longitudinal plica on each si(k^, and has two tubercles a 

 little before the hind margin. The 7th segment is 

 thickly covered with 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 

 7 til segment is absent. 



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



5. Mi/nncdoniafortunota,w.B^. Rufo-testacea, nitidula, 

 capite nigro, antennis apicera versus, pectove, elytroruni 

 lateribus, abdominisque segmento 5" infuscatis; capite pro- 

 thoraceque subquadratocrebre fortiter punctatis; elytris hoc 

 fere brevioribus, crebre minus fortiter punctatis; abdomine 

 supra Itevigato, subtus sat crebre punctato. Long. 3j lin, 



AnteniiEe rather long, moderately stout, the four basal 

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

 lono- as the 2nd ; 4th intermediate in length between the 

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

 than broad; 5 — 10 diifering 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 ]«mcture.d. Thorax yellowish, about 

 as long as broad, slightly narrowed behind, veiy coarsely 

 punctured, obsoletely depressed on each side the disc. The 

 elytra yellowish, infuscate about the apical angle, scarcely 

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

 rately finely punctured. The bind body is yellowish, the 

 segments irregularly marked with a pitchy colour ; before 

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

 punctate above ; distincth/ and vioderatvltj closelij ]iunc- 

 tured beneath. Legs pale yellow, with 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 irregularly Avaved lines. 



Ega ; one female individual.
