tarsi cleft at tip and with a sharp triangular tooth at base, and 

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



(J. Ninth ventral segment small, oblong, subtruncate at the tip, 

 a single spiniform process projecting from the internal sac. 



Hab. Guatemala, Quiche Mts. 



Three males and five females seen, showing no variation 

 in colour. The structure of the (J anterior tarsal claws 

 was not observed by Gorliam, who gives the outer claw of 

 the middle and hind tarsi only as cleft. A narrow, slender 

 insect related to D. carbonarium, which came from the 

 same locality ; but much smaller, and also differing from 

 it in the shape of the prothorax in both sexes, the small 

 eyes of the male, etc. The Mexican D. subtenue is very 

 like D. tenue. 



11. Discodon maurum, n. sp. (Plate VIII, fig. 52, 

 prothorax, (J.) 



Discodon melancholicnm, Gorh., Biol. Centr.-Am., Coleopt. 

 iii, 2, p. 81 (part.). 



^. Narrow, finely pubescent, somewhat shining, wholly deep 

 black. Eyes somewhat prominent. Antennae very long, filiform. 

 Prothorax small, transverse; the sides strongly refiexed, deeply 

 sinuate and feebly obliquely notched at about the middle, and with 

 an abrupt notch immediately before the dentiform hind angles 

 (these being formed by the refiexed basal margin) ; the disc broadly 

 sulcate down the middle behind, appearing bicallose. Elytra 

 wider than the prothorax, very elongate, subparallel. Inner claw 

 of anterior and outer claw of the other tarsi cleft at tip. 



Length 8, breadth 3 mm. 



Hab. Mexico, Parada in Oaxaca {Salle), Oaxaca {Mus. 

 Brit.). 



Two males — one included by Gorham under D. melan- 

 cholicum (= D. triste), the other acquired by the British 

 Museum in 1858. In the male of the present species one 

 claw of each tarsus is cleft (not easily seen), the prothorax 

 is small, with strongly upturned margins, and the sides 

 abruptly notched immediately before the base, and the 

 antennae are long and filiform, characters readily dis- 

 tinguishing D. maurum from D. melancholicum. 



12. Discodon nigropilosum, n. sp. 



Moderately elongate, shining, nigro-pilose ; black, the sides of 

 the prothorax narrowly (c^) or rather broadly ($) flavous, the very
