broad black median vitta sometimes extending along the anterior 

 margin to the lateral notch in 3*. Eyes small. Antennae {^) about 

 as long as the body, dilated, subserrate, and densely clothed with 

 short projecting hairs ; ($) much shorter and moderately stout, more 

 sparsely pilose. Prothorax ((J) transverse, deeply, angularly, 

 abruptly emarginate at the sides at about the middle (the lateral 

 margins thus appearing dentate at the apical third), the hind angles 

 subrectangular ; ($) shorter and more transverse, the sides somewhat 

 rounded, narrowly reflexed, and feebly sinuate. Elytra wider than 

 the prothorax, moderately long, slightly rounded at the sides in $, 

 finely punctate and costulate. Inner claw of anterior tarsi, and 

 outer claw of the other tarsi cleft at tip, in ^. 



(J. Eighth ventral segment narrowed to the apex, the apex itself 

 cleft in the middle, appearing bilobed. 



Length (excl. head) 5-5|, breadth 1^-2 mm. (^J $.) 



Hab. Guatemala, Quiche Mountains, 7000-9000 ft. 

 (Champion). 



Five males and two females. The black pubescence, 

 the very long, stout, subserrate, densely pilose antennae 

 of the male, the less parallel elytra, and the rounded, much 

 less sinuate sides of the prothorax in the female, readily 

 distinguish the present species from D. cinereimi, under 

 which the specimens described were left in the " Biologia" 

 collection.

Hab. Guatemala, San Geronimo in Baja Vera Paz. 



Described from two females. T. comptus, in the absence 

 of the male, is best placed near Discodon nigropilosum, also 

 from Guatemala, it having a feebly developed head, small 

 eyes, long, serrate antennae, and rugose elytra, much as 

 in the female of that species ; the prothorax, however, in 

 T. comptus is wider than the base of the elytra, and strongly 

 rounded and broadly explanate at the sides from near 

 the acute hind angles. The species obviously bears no 

 relationship to the genus Telephorus, s. str. 



14. Discodon sinuatum, n. sp. 



Moderately elongate, rather narrow (cJ), broader ($), opaque, 

 finely pubescent; nigro-piceous or black, the prothorax sometimes
