pressed hook projecting on each side at the apex from beneatli the 

 prominent outer apical portions of the segment (fig. 8a). 

 Length (excl. head) 10-1 1|, breadth 3t-H mm. ((j' ?.) 



Hab. Panama, Volcan de Chiriqui, Bugaba. 



Two males and five females. Gorham correctly surmised 

 that the Panama examples referred by him in his " Supple- 

 ment " to D. flavicolle (= plicatum, var.), were not con- 

 specific with those from Mexico. In the Chiriqui insect 

 the oblique lateral notch of the prothorax is placed nearer 

 the base, and the outer claw of the middle and posterior 

 tarsi is more deeply cleft (the two portions differing con- 

 siderably in length), in the male, the basal margin of the 

 prothorax is more reflexed, the elytra are more shining, etc. 



29. Discodon fuscipenne, n. sp. 



(J. Elongate, somewhat shining, clothed with rather long pubes- 

 cence ; nigro-piceous, the legs paler (due to immaturity), the points 

 of insertion of the antennae, the base of the mandibles, the pro- 

 thorax, and the anterior and middle coxae straw-yellow. Antennae 

 long, slender, sparsely pilose. Eyes large, prominent. Prothorax 

 transverse, arcuate in front, the sides subparallel behind, and with 

 a narrow, oblique notch at about the basal fifth. Elytra long, sub- 

 parallel, wider than the prothorax. Inner claw of anterior tarsi 

 broadly lobed, and outer claw of the other tarsi cleft at tip, in (J. 



Ninth ventral segment narrow, a stout curved hook projecting 

 from the internal sac on each side and a central process also visible 

 (fig. 9). 



Length (excl. head) 8^, breadth 3 mm. 



Hab. Guatemala, Cerro Zunil, Pacific slope (Champion). 



One male, included by Gorham under the series of 

 D. plicatum, an insect also occurring at Cerro Zunil. The 

 juxta-basal position of the prothoracic notch in the male 

 readily separates D. fuscipenne from the same sex of D. 

 plicatum, v&t. flavicolle; and the parallel-sided prothorax, 

 with narrow notch near the base, distinguishes it from the 

 southern D. stramineicolle, (^. The prothorax is small and 

 the elytra are very elongate, as in the last-named insect. 



30. Discodon planicolle. 



Polemius planicollis, Lee, Journ. Acad. Phil., iv, p. 17 

 (1858); Trans. Am. Ent. Soc. ix, p. 55 (nee T. 

 planicollis, Kies.).
