 Lema, var. immaculicollis, Chevr. Col. Mex. cent. ii. 1835, no. 112. 

 Lema trivirgata, Leconte, Col. of Kansas, 1859, p. 22. 

 Lema lecontei, Clark, Cat. Phyt. 1866, p. 31. 

 Lema trivittata, Say, Journ. Ac. Phil. iii. p. 429. 



Hab. N. Ameeica. — Mexico ; Honduras ; Costa Rica. — Cuba. 



Var. immaculicollis, Chevr., has also been received from Honduras. 



22. Lema nigrovittata. 



Lema nigrovittata, Guer. Ic. Regn. Anim. iii. p. 262 1 ; Lacord. Mon. p. 421. 

 Lema melanocephala, Dej. Cat. 3rd ed. p. 386. 



Hab. N. Ameeica, California 1 . — Mexico. 



This species is very closely allied to the preceding one, and is equally variable. It 

 is, however, less robust and smaller ; and the submarginal stripe is not placed so close 

 to the outer margin as in L. trilineata. 



23. Lema opulenta. 



Lema ornata, Baly, Ann. & Mag. Nat. Hist. ser. 3, xvi. p. 158 l (nee Gravenh.).

Sab. Guatemala 1 , Zapote, Duenas (Champion). 



The Munich Catalogue name, L. opulenta, Harold, has been substituted for that 

 given by Mr. Baly, whose title is unfortunately preoccupied. I am, however, quite 

 unable to find any reference to the subject in part xiii. of the Coleopterologische 

 Hefte, or any mention of the species. 



24. Lema abrupta. 



Lema abrnpta, Lacord. Mon. p. 422. 

 Hab. Mexico. 



25. Lema salvini. 



Lema salvini, Baly, Cistula Entom. pt. ii. 1878, p. 313.

Lema semisepta, Lacord. Mon. p. 423 \ 



Hab. Guatemala, Capetillo (Champion). — Beazil 1 . 



I refer a single specimen sent from Guatemala to this species ; it differs, however, in 

 several particulars : the tibiae and knees are black, as well as the antennae, with the 

 exception of the last two joints, which are rufous ; the thorax is as broad as long; and 

 the elytral spot is absent as in Lacordaire's var. a.
