LIG-YKUS. 317 



Hdb. Mexico, Cordova, Acapulco and Chilpancingo in Guerrero, Tapachula in 

 Chiapas (Edge) ; Beitish Hondueas, R. Sarstoon, Belize (Blancaneaux). 



Agrees in some respects with Burmeister's description of his L. fossator, but he says 

 the anterior tibiae are without trace of tooth above the third. An example from 

 Acapulco is figured. 



6. Ligyrus nasutus. (Tab. XVIII. fig. 17, «? .) 



Podalgus nasutus, Burm. Handb. der Ent. v. p. 120 l . 



Hab. Mexico, Acapulco and Chilpancingo in Guerrero (Edge), Yucatan 1 ; Guate- 

 mala \ San Geronimo (Champion). 



Twelve examples, in all of which the frontal carina is continuous (without median 

 depression), and at each end connected with the side of the head by a short lower 

 carina. The weak marginal tubercle of the thorax mentioned by Burmeister exists at 

 most only as a triangular flat projection of the anterior margin, and in many examples 

 is entirely absent. The pygidium is smooth and polished, generally with a few 

 scattered punctures. A specimen from San Geronimo is figured. 



7. Ligyrus pygidialis. 



A prascedente differfc carina frontali medio depressa vel divisa plerumque utrinqne abbreviata, pygidioque in $ 



medio apice depresso utrinque obtuse calloso. 

 Long. 16-18 millim. tf $ . 



Hab. Mexico, Temax in North Yucatan (Gaumer). 



A very large series of examples, constant in their differences from L. nasutus. The 

 thoracic tubercle is very seldom wanting, and is sometimes a little elevated and 

 followed by a faint depression. 



8. Ligyrus fossor. 



Scarabaus fossor, Latreille in Humboldt and Bonpland's Obs. Zool. ii. p. 11, t. 31. f. 2 (1833) \ 

 Podalgus fossor, Burm. Handb. der Ent. v. p. 119 2 . 

 Ligyrus fossor, Burm. loc. cit. p. 542. 



Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet, Taboga Island (Champion). — 

 South Ameeica, Colombia 1 2 . 



Very similar to L. nasutus and L. pygidialis, agreeing with the latter in the frontal 

 carina being depressed in the middle (it is, in fact, interrupted and each half much 

 less raised) ; but it differs from both in the pygidium being coarsely umbilicate-punctate, 

 and the clypeus truncate-edentate. The frontal tubercle of the thorax is very slightly 

 indicated. Mr. Champion obtained two examples only.
