26 PHYTOPHAGA. 



* 



MEGALOPUS. 



Megalopus, Fabricius, Syst. El. ii. p. 367. 



Up to the present time no species belonging to this genus has been recorded from 

 Central America, all of them inhabiting South America. 



1. Megalopus inscriptus. 



Megalopus inscriptus, Klug, Ent. Mon. p. 61, t. 4. f. 6; Lacord. Mon. p. 709 *; Dej. Cat. iii. 

 p. 385. 



Hob. Mexico, Panistlahuca, Cordova (SalU). — Cayenne 1 . 



The species agrees perfectly with the typical description, and may be recognized by 

 the distinct M-shaped black mark on the thorax ; the basal part of the elytra is of a 

 lighter colour than the rest and limited obliquely by the darker portion ; the female is 

 much smaller, and the posterior thighs do not extend beyond the abdomen, which is 

 the case to a great extent in the male insect. I believe that this species is identical 

 or very closely allied to M. searvittatus, Bates. 



Pam. CLYTHBIDJB. 



Subfam. CLYTHEIN^l. 



This subfamily is not very numerously represented in Central America. Of the 

 twelve genera belonging to it, four only are found in the subregion, each with a few 

 species, as far as our present knowledge extends. 



TITUBCEA. 



Tituboea, Lacordaire, Mem. Liege, v. p. 141 (1848). 



This genus has been split up by Lacordaire into six subgenera ; but their characters 

 are not clearly denned and certain, and in the Munich Catalogue they are all united 

 under the generic name of Titubcea. There are five Central- American species. 



l. Tituboea humerigera. 



Anomcea humerigera, Lacord. Mon. p. 140 1 . 

 Eab. Mexico 1 , La Parada {Salle). 



A single female from La Parada differs from the type in having an additional small red 

 spot near the apex and close to the suture of each elytron.
