1. Microrhagus unicus. 



Microrhagus unicus, de Bonv. Mon. p. 575, t. 27. fig. 8 \ 

 Hab. Mexico, Teapa (coll. Chevrolat *). 



This species has a moderately wide clypeus at the base, the antennae of the male 

 pectinate, the propleural groove rather wide behind, its outer carina obliterated poste- 

 riorly, and the elytra distinctly striate. 



No specimens have been seen by us. 



2. Microrhagus sepositus. 



Cylindrical, moderately convex, piceous-black, shining, indistinctly clothed with short fulvous pubescence': 

 antennae brown, half as long as the body, strongly serrate from the fourth joint ; head convex, neither 

 carinate nor impressed, closely punctate, not rugose except on the occiput, clypeus wider at the base than 

 the distance to the eye ; thorax a little wider than long, sides straight and parallel, rounded at the front 

 angles, disc convex, a very faint indication of a median impression, an oblique impression each side of the 

 middle of the base, surface coarsely and closely punctate, not rugose, more finely at the apex ; elytra 

 almost absolutely without striae, the sutural stria very short and apical, surface moderately closely punc- 

 tate, dense and subrugose at the base, more sparse at the apex, where several of the intervals are acutely 

 granulate ; posterior supplementary line of the propleurae extending halfway to the apex, outer carina 

 of the groove entire ; abdomen moderately closely punctate ; legs piceous, tibiae and tarsi sometimes 

 ferruginous. 



Length 3-5 millim. 



Hab. Guatemala, San Juan in Vera Paz (Champion). 



According to the table by de Bonvouloir, this species is closely related to 

 M. pyrenceus, which, however, has the elytra more or less striate and the base and 

 suture rufescent. 



3. Microrhagus repandus. 



Cylindrical, moderately convex, narrowed behind in both sexes, piceous-black, shining, very sparsely pubescent, 

 the cinereous pubescence quite conspicuous at the sides and base of the thorax and at the basal third of 

 the elytra ; antennae piceous, a little longer than half the body in both sexes, joints 3-10 pectinate ( <$ ), 

 the branches one half longer than the joint, serrate ( $ ), the joints but little longer than wide at the 

 apex ; head densely subrugosely punctate, not carinate or impressed, eyes entire, clypeus very narrow at 

 the base ; thorax subquadrate, nearly as long as wide, sides with a slight sinuation at the middle, arcuately 

 narrowed near the apex only, disc convex, slightly depressed in front of the hind angles, a carina at the 

 middle near the base, usually well elevated, surface very coarsely closely punctate but not rugose • elytra 

 usuaHy very indistinctly striate, intervals muricately punctate, densely and roughly at the basal third, more 

 sparsely towards the apex ; propleural groove deep and parallel, the outer edge sharp and entire, the 

 posterior supplementary line extending two-thirds to the apex ; body beneath piceous-black, shining, 

 abdomen rather coarsely and closely punctate • legs ferruginous, the femora sometimes infuscate. 



Length 3-3*5 millim. 



Hab. Guatemala, San Juan and Chiacam in Vera Paz, El Reposo, San Isidro 

 (Champion) ; Panama, Bugaba, Volcan de Chiriqui, Caldera, Tole (Champion). 



This species is evidently related to M. amazonicus, but is smaller, and differs in the 

 rougher sculpture at the base of the elytra and other minor details. De Bonvouloir does
