I have already referred to the fact that in by far the larger number 

 of genera of Harpalini the labial palpi have the last joint shorter than 

 the preceding, while the latter is then more than bi-setose except in 

 Glyptus which seems to have lost the setse entirely. In the Dapti 

 Agonoderus has been referred to as one of the rare exceptions to the 

 rule and the terminal joint is as long or longer than the preceding and 

 the latter simply bisetose in front. The presence of a few hairs more 

 or less may seem a very trivial character, but when this is always 

 associated with another important structural character and is moreover 

 absolutely constant, it assumes an importance far greater than the slight 

 ligular differences which are apt to be described and even figured differ-* 

 ently by two equally competent students. 



In order that the argument may be followed more easily it will be 

 better to discuss the genera separately, and will call the labial palpi 

 normal when the last joint is short and the preceding plurisetose. 



Stenomorphus. — Labial palpi normal. Anterior tarsi of male moder- 

 ately dilated, the first joint nearly equal to the three following and not 

 squamulose beneath, the next three biseriately squamulose, the fourth 

 transverse feebly emarginate. Anterior tibiae ciliate within. Middle 

 femur with a triaugular dilatation of the anterior condyle at the knee, 

 the middle tibia slightly arcuate, middle tarsus not dilated. Mandibles 

 chisel-shaped at tip. 



The female has the first joint of the anterior tarsi rather broadly 

 dilated and not spongy nor papillose, the tibia is not ciliate within. The 

 middle femur is not toothed at apex, the tibiaj slightly curved. 



It will be seen by the above characters that the genus should not be 

 placed with Anisodactylus as stated by Schaum, much less with the 

 Pogonini as Lacordaire has done. 



GrYNANDROPUS. — The labial palpi are normal. The anterior tarsi 

 are moderately dilated in the male, the first four joints biseriately 

 scjuamulose, the first about as long as the next two. The female is 

 as in Stenomorphus. 



This genus makes a nearer approach to the true Harpali than the 

 ]»recediiig. 



TRioiiopsELAPHrs. — Palpi unknown, probably normal. The anterior 

 tarsi of male with four joints dilated and squanudose beneath, joints 1 — 4 

 decreasing gradually in length, the fourth emarginate. Posterior tibife 

 arcuate, inner edge crenulate and ciliate. In the female the first four 

 joints are dilated, the first strongly, much longer than any of the fol- 

 lowing joints, not squamulose or spongy beneath.
