out, but more decidedly so in advance of its middle, the surface 

 granulose, but not at all rugose or tuberculate; anterior margin 

 truncate, the apex rounded and widely subtruncate; the lateral lobes 

 provided with a sinuation immediately back of the lateral lobe, which 

 is obliquely rounded and directed a little to the rear and outward. 

 Tegmina and wings wanting. Head rather broad, set into the front 

 edge of the pronotum almost to the eyes; the vertex convex, almost 

 as wide again as one of the eyes, its front roundly advanced, its an- 

 terior margin without a transverse carina and gradually merging with 

 the upper portion of the front; the frontal costa continuing above as a 

 prominent carina through the middle of the vertex and extending 

 backward halfway to the anterior edge of the pronotum, rather pro- 

 foundly sulcate, the rami diverging somewhat strongly from a little 

 above the posterior ocelli to a point drawn across the face from below 

 the lower ocellus, and, when viewed laterally, roundly prominent be- 

 tween the antennse. The latter arise just within a line drawn between 

 the lower edge of the eyes, are slender and of moderate length. An- 

 terior and middle femora elongate, several times as long as wide, the 

 carinae not at all foliate or lobate; hind femora robust; hind tibiae with 

 few spines, irregularly placed, the first joint of the tarsi at least one 

 and one-half times as long as the third. Valves of the ovipositor 

 robust and evenly and strongly serrated. 



General color dark fuscous, the apical half of the pronotum and 

 markings on the hind femora bruneo-testaceous, the tibiae obscurely 

 fasciate. Lower outer edge of the hind femora black. Abdomen 

 varied with dusky and pale markings. 



Length of body, 9 , lo mm.; of pronotum, 6.5 mm.; of hind femora, 

 6 mm.

1 The name of this part of Africa in the EngHsh language is Cameroon. When 

 the Germans seized it, they Germanicized the name, calling it " Kamerun." 

 Now that the French are administering it, they write the name " Cameroun." I 

 propose to stick to the English spelling, which antedates all others. W. J. Holland.
