squarer, and the triangular projection of the middle over the 

 head is not so great and is wider ; the posterior angles are 

 rounded at the points and channelled. The elytra are widest 

 about the middle, and slope more gently both backwards and 

 forwards ; the swollen lateral expansion is longer, narrower, and 

 not so tumid ; the humeral blade is longer ; the sutm-e in the 

 male is curved concavely behind the middle, and the apex 

 truncate obliquely, terminating at the sutural angle in a sharp 

 little yellow tooth ; in the female the suture is straight, and 

 the apex rounded ovately ; tibise simple. 



This I think the handsomest of the West-African Lycidae, 

 It is apparently rather rare, not many specimens having 

 reached me. 



§ 3. Elongate, attenuate at the apex ; tlie elytra in neither sex expanded 

 nor armed with blades or spines on the shoulders.

Of this I received several specimens, divisible into two 

 groups, one larger than the other, and with longer and propor- 

 tionately more slender antennai : they were, doubtless, the 

 sexes, the one with longer antennae probably the male. The 

 abdomen in some is black, but in most is slightly margined 

 with yellow; and the median black stripe on the thorax is 

 broader in some than in others.

[A portion of the following translation was prepared some 

 years ago ; but the difficulty of accepting the author's conclu- 

 sions, without some modification which there was then no means 

 of verifying, caused it to be laid aside. Quite recently I have 

 received from Professor Seguenza a number of specimens, the 

 careful examination of which has led to results differing in one 

 or two important particulars from those detailed in his paper,
