MICROKHAGUS.— FARSUS. 253 



the prosternum acute ; body beneath piceous, coarsely closely punctate ; posterior coxal plates equally 

 broad, not dilated internally ; legs paler reddish-brown, femora somewhat darker. 

 Length 3-4 millim. 



Hab. Guatemala, Las Mercedes (Champion) ; Panama, Volcan de Chiriqui (Champion). 



Allied to M. humeralis, but differs in colour and by the absence of any median 

 impression on the thorax. In well-preserved specimens the fulvous pubescence of the 

 thorax is more distinct at the sides and hind angles. 



FARSUS. 



Farsus, Jacquelin-Duval, Gen. Col. Eur. iii. p. 116 (1860) ; de Bonvouloir, Mon. des Euenemides, 

 p. 618. 



This genus is closely related to Microrhagus and Arrhipis, differing from the former 

 in the absence of a well-defined depression along the inner edge of the propleurse, and 

 from the latter by having the inferior marginal line which continues the apical margin 

 prolonged well backward. 



1. Farsus obscurus. 



Farsus obscurus, de Bonv. Mon. p. 624, t. 30. fig. 6 1 . 



Hab. Mexico, Toxpam, Cordova (SalU l ) ; Nicaragua, Chontales (Belt). 



The only specimens seen are unfortunately in bad condition. 



2. Farsus oblitus. 



Cylindrical, moderately convex, slightly narrower behind, varying in colour from brown to piceous, subopaque, 

 sparsely pubescent : antennae slender, varying in colour from ferruginous to piceous? a little longer than 

 half the body ; head convex, a vague triangular impression at the base of the clypeus, densely rugosely 

 punctate, the clypeus nearly as wide as the distance to the eye ; thorax nearly as long as wide, sides 

 parallel at the basal half, then arcuate to the apex, convex, the disc slightly depressed, a slight smooth 

 median line behind the middle, slightly elevated at the base, no basal oblique impressions, surface densely 

 asperately punctate ; elytra vaguely striate, the intervals closely punctate, densely at the base ; prosternum 

 coarsely closely punctate, the impression of the propectus limited behind by a distinctly elevated transverse 

 line ; abdomen moderately closely but indistinctly punctate ; legs yellowish-testaceous. 



Length 3-4 millim. 



Hab. Guatemala, Mirandilla, Torola (Champion) ; Panama, San Lorenzo in Chiriqui 

 (Champion). 



Allied to F. elevatus, which has a similar transverse line limiting the impression 

 of the propectus ; but differs in the absence of oblique impressions at the base of the 

 thorax and by the longitudinal impression of the head. Three specimens, the one of 

 paler colour evidently less mature.
