 each row. Subgenital plate in the male with the styles long, 

 projecting beyond the apex of the plate.

Genus Pharmacus, Pictet and Saussure. (1891.) 



Form slender. Head vertical; antenna thick, hairy, 

 rather distant at their insertions. Fastigium narrow, deeply 

 sulcate. Eyes ovoid, their internal margins straight. Pro- 

 notum rounded anteriorly, projecting over the occiput ; the 

 posterior margin straight, the posterior angles slightly 

 rounded. Sternum rather broad. Legs long and slender, 

 hairy, except the hind femora. Coxae separated from each 

 other, those of the fore legs spined. All the femora without 

 apical spines. Fore and middle tibiae with an inferior pair of 

 apical spines, and a single superior one on the posterior side. 

 Hind tibiae unarmed below; the apical spurs are two pairs, 

 the superior of which are not twice as long as the infe'rior and 

 less than half the length of the first joint of the tarsus. First 

 and second joints of the hind tarsi terminated above by two 

 short spines. Supra-anal plate large and rounded, passing 

 the cerci, which are moderate. Subgenital plate in the male 

 longer than the pronotum, triangular, slightly keeled ; the 

 styles large, cylindrical, inserted before the middle of the 

 plate.
