2. Anisotarsus virescens. 



Harpalus virescens, Dejean, Sp. Gen. Col. v. p. 839. 



Hab. Mexico. 



Dejean's type specimen, communicated to me by M. Rene Oberthiir, is a male.

3. Anisotarsus chloroderus. 



■ 



Subtus rufo-piceus, supra sericeo-nitens, capite thoraceque viridi-seneis, elytris cupreo-fuscis seneo tinctis ; 

 antennis (articulis l°-5 m plus minusve nigro maculatis), partibus oris pedibusque rufo-testaceis ; thorace 

 quam elytra distincte angustiore, transversim quadrato, paullo ante medium leviter rotundato-dilatato, 

 deinde antice plusquam postice modice angustato, angulis posticis valde obtusis sed distinctis, supra 

 impunctato, foveis basalibus elongatis, profundis ; elytris oblongo-ovatis, apice paullulum oblique sinuatis, 

 acute striatis, interstitiis subplanatis apud apicem multo angustioribus, sub lente subtilissime strigulosis, 

 3° versus apicem unipunctato. 



Long. 4f-5 lin. c? $ . . 



Hab. Mexico, Puebla, Cuernavaca (Salle).

Distinguishable from A. ocreatus (besides its brighter metallic 



) by the form 



of the thorax, which is relatively much larger, more convex, more strongly rounded a 



■ 



little before the middle, and more narrowed towards the base, with the surface not

perceptibly flattened towards the hind angles, which latter character is distinctive of 

 A. ocreatus and its allied North- American species. It is so closely allied to A. virescens^ 

 Dej., that I have some doubt of its being distinct. The different colour of the elytra is 

 almost its only distinction.

4. Anisotarsus purpurascens. 



/ 



A. ocreato affinissimus, sed brevior, colore utriusque sexus purpurascenti-nigro-fusco, marginibusque concoloribus 

 etc. Brevius oblongo-ovatus, piceo- vel nigro-fuscus, supra (prsecipue elytris) purpurascens ; antennis 

 (articulis 2°-6 m plus minusve nigro maculatis), palpis pedibusque melleo-flavis ; thorace breviter transversim 

 quadrato, medio paullulum rotundato dilatato, postice gradatim, antice citius sed paullo angustato, angulis 

 obtusis, supra impunctato, marginibus posticis minus quam in A. ocreato explanatis, hand rufescentibus, 

 foveolis basalibus paullo depressis ; elytris baud sericeis, paullo fortius striatis, apice minus prolongatis, 

 purpurascenti-fuscis subnitidis. 



Long. 4-4^ lin.

Sep 



some hesitation, from the variable A 



but it seems 



■ 



constantly distinct by its shorter elytra, the absence of pale margins, the more rounded 

 thorax, and the purplish pitchy-black colour in both sexes. The female also has not 



the 



g 



lustre and the very feeble 



of A 



bears the name A. poeciloides, Chevrolat, in the Salle 



itus. The sp< 

 which I have 



adopted on account of its having been used in the very closely allied genus Aniso- 

 dactylus.
