354 SEREICOENIA. 



There are three specimens of this species in the Janson collection, one from that of 

 Schaum. The insect resembles M. aversus, but it is broader and has very distinct 

 coarser intermixed punctures on the thorax.

 Antonio (Champion), Zacapa (Salle *) ; Nicaragua, Chontales (E. M. Janson) ; Panama,

 (Bates). 



This extremely variable insect has been found in plenty in many of the above-quoted 

 localities. The numerous specimens from Champerico on the Pacific coast, and some 

 others from Tehuantepec, Morelia, and Tole, are in great part black and unusually 

 large; those from Tabasco, Ega, &c. are very small and brightly coloured. The 

 tuberculate base of the thorax distinguishes it readily from the closely allied M. bellus *. 

 We figure two extreme varieties — one from Champerico and one from San Juan 

 Bautista.

This species appears to be much rarer in Central America than M. pictus. The 

 specimens irom Tabasco and British Honduras are in great part rufo-testaceous, the 

 thoracic markings being reduced to two or four spots on the disc (entirely obsolete in 

 one specimen), and those on the elytra to some marks at the base and sides and a 

 sharply angulated fascia near the apex. I have examined the type of M. variegatus, 

 Steinh. Specimens from Monte Video and Buenos Ayres, in the Janson Collection, 



* M. pictus, Cand., is incorrectly sunk as a synonym of M. bellus, Say, by M. Fleutiaux : cf. Ann. Soc. Ent. 

 Belg. 1895, p. 168.
