Several specimens found at an elevation of 8600 feet. A single example only was 

 obtained on a former occasion. 



LUCANIDiE. 



Charagmophorus lineatus, Waterh. 



This genus and species were described from a single male example. Other males and 

 two females have now been found at 8600 feet. 



The female has the elytra as in the male, with lines of very small grey scales ; but 

 tlie head and thorax are shining. The mandibles are short. The head is sparsely 

 punctured posteriorly, rather strongly transversely impressed in front and strongly and 

 closely punctured. The thorax is rather more convex than in the male, a little narrowed 

 anteriorly, ol)tusely angular at the sides at a short distance from the base, moderately 

 finely ptmctvired, the punctures rather unequal, not very sharply defined, separated 

 from each other by two to three diameters of a puncture ; the margins are impressed ; 

 the disk is longitudinally impressed. The front tibia? have the five teeth rather stronger 

 and more approximate than in the male ; the posterior tibiae have a small acute tooth at 

 the middle. 



DASCILLIDiE. 



ExAGONTUS, gen. nov. 



Mentum a little broader than long, slightly narrowed anteriorly, corneous ; ligula 

 broad and transverse, acuminate at the sides ; labial paljii three-jointed, the basal joint 

 elongate, the second a little shorter, pear-shaped, the third somewhat the same shape but 

 inverted, acuminate at the apex. Maxilloe with two delicate subequal lobes ; the galea 

 consists of two portions, the basal part parallel, the apical portion shorter, clothed with 

 stiff hair ; the lacinia terminates in a curved acute tooth, which is surrounded by curved 

 stiff bristles. Maxillary palpi rather long, robust, hairy ; the basal joint rather short, 

 narrowed at its base ; the second joint stouter, at least twice as long as broad, gradually 

 and not very much narrowed towards the base ; the third joint similar in shape but a 

 little shorter ; the fourth a little longer than the second, club-shaped, acuminate at the 

 apex. Mandibles strong, curved, concave below, very acute at the apex, with a small
