184 OEO. H. HORN, M. D. 



are included in Harpalns. The mouth parts of vulpeculus 139, show 



some difference from those figured as Marpalus, but the other two 



species have the Hgula and paraglossae as in fig. 188, except that the 

 paraglossfe are not ciUate. 



Group Anisodactvli. 



The essential character of this group is that the dilated tarsal joints 

 of the male are spongy pubescent beneath. 



As constituted by Lacordaire it contains very diverse forms — Ortlio- 

 gonius is a distinct tribe, Oratognathus and Flowma are Dapti, Geo- 

 hsenus allied to Platt/nua ; Migadops, Loxomerus and Brachycoelus are 

 Carabinae, GynandropiiDi and Diavhromus go to the Harpali ; Gynandro- 

 tarsus has already been suppressed in Anisodacty/us, and I hope to 

 show good reasons for doing the same with Gynandromorphus. 



The genus Anisodactylus not only gives its name to the group but is 

 also its central idea. From this as a starting point the relative values of 

 the genera may be discussed, as a convenient point of comparison. 



In a ri!view of our species of the genus published by me, (Proc. Am. 

 Philos. Soc. 1880, p. 1(J2, etc.), will be found a full discussion of the 

 characters which serve to divide the species in subgenera and lower 

 groups — the trifid anterior tibial spur, the spur broader at middle and 

 the slender spur. In two species harpaloides and vpacidus, the first 

 joint t)f the anterior tarsus of the female is dilated and in the former 

 that joint is somewhat prolonged under the second. 



Gynamh'nmorphua has the trifid anterior tibial spur in both sexes, 

 the first joint of the anterior tarsi dilated in the female while the 

 posterior tarsi are somewhat flattened and pilose above. In the first 

 character it is ecjually related to the Dichirus and Triplectrus groups of 

 Anisodactylus, by the second to the latter more especially and by the 

 third character to the former more especially. The upper surface is 

 densely and rather coarsely punctured and finely pubescent. I have 

 therefore no hesitation in placing Gynundromorphus as a division of 

 Anisodavtylus intermediate between the groups Dichirus and Triplectrus. 



Xestonotus. — Anterior tarsi broadly dilated in the male, the first 

 four joints densely spongy pubescent beneath, middle tarsi' with four 

 joints less widely dilated and spongy pubescent beneath, the first entirely 

 glabrous, posterior tarsi slender and long. Elytra with one dorsal punc- 

 ture. The ligula is rather narrow and parallel, the paragloss«3 broad 

 and a little longer than it. 



Comparing the diiferences between the ligula and paraglossse with 

 those observed in Ha r palm there does not seem any valid reason for
