tarsi is split, wliereas the large claw to all tlie tarsi is split 

 in Amhlyterus. Lacordaire says that this claw is not 

 "fissile" in the anterior pair, but this is evidently a 

 mistake ; he states, also, that the labrura is very prominent 

 in the middle. I have only dissected one specimen, and 

 in that it is not prominent at all in the sense in Avhich the 

 term is used with regard to the species of this family. 

 I do not trace any membranous border to Mest/stcechiis, 

 and it is so slight in Amblyterus that it is seldom visible.

Oblongus, convexus, nitidus, flavo-piceus ; fronte tho- 

 raceque nigro-feneo variegatis ; scutello piceo, punctulato ;

Long. 4 1 lin. 



Clypeus densely rugulose, with the fine reflexed margin 

 pitchy-black. Head blackish, with a spot in front 

 yellowish, thickly and rather strongly punctured, less so 

 on the vertex. Thorax one-third broader than long, 

 convex, pitchy-yellow, not very thickly but rather 

 strongly punctured ; the sides arcuate, a mesial line and 

 an irregular patch on each side (all sub-confluent) bronzy- 

 black. Elytra a trifle broader than the thorax, a little 

 longer than broad, with two double lines of rather strong 

 punctures on the dorsal region of each, and four lines on 

 the sides; the broad interstices with strong punctures, 

 which have a tendency to form irregular lines. The 

 margins are beset with short stiff" hairs. The under side 

 is variegated with brownish -black, moderately pubescent.
