282 PHYTOPHAGA. 



30. Lactica chontalensis. (Tab. XVI. fig. 22.) 



Oblong, slightly widened behind, testaceous ; antennae and legs more or less distinctly piceous ; thorax and 

 elytra impunctate, testaceous, a transverse band at the base of the elytra, blacki&h. 



Length 1£ line. 



Head impunctate; frontal tubercles small and obsolete ; carina distinctly raised, somewhat curved and convex; 

 eyes very light fuscous or testaceous ; antenna* half the length of the body, piceous, third and fourth 

 joints of equal length ; thorax transverse, of equal width, the sides slightly concave, transverse basilar 

 sulcation moderately deep ; scutellum testaceous ; elytra rather convex and slightly widened towards the 

 middle, without basal depression, entirely impunctate, the base to nearly the middle occupied by a 

 transverse blackish band which does not quite extend to the basal nor lateral margin. 



Eab. Nicaragua, Chon tales (Janson). 



The two specimens obtained by Janson agree in most essential points, but one of 

 them has the antennae wanting and the legs of a lighter colour ; the eyes are also a little 

 wider apart. The concave sides of the thorax and size and shape of the elytral band 

 will distinguish the species from L. variabilis. 



31. Lactica ornata. (Tab. XVI. fig. 19.) 



Ovate, rufous; antennae (the first two joints excepted) black; elytra impunctate, each elytron with a 

 subquadrate spot at the base, violaceous blue. 



Length 1| line. 



Head very minutely punctured, frontal tubercles small and indistinct, carina distinctly raised ; antennae half 

 the length of the body, rather robust, the first two joints rufous, the rest black; thorax transverse, the 

 sides rounded, basal sulcation distinct, but not very deep, surface impunctate ; elytra with a shallow 

 transverse depression below the base, of a little lighter colour than the thorax, impunctate with a square- 

 shaped spot extending to the lateral but not to the sutural margin, dark violaceous blue; underside 

 covered with fine silk-like yellowish pubescence ; tarsi obscure piceous. 



Hah. Mexico, Puebla {Salle). 



Although there is unfortunately only a single specimen of this pretty little species 

 contained in the collection of M. Salle, it cannot be mistaken for any of its allies on 

 account of its bright and well-marked coloration in connexion with its small size. 



32. Lactica violaceipennis. 



Camcena tibialis, Baly, Journ. of Ent. i. 1862, p. 459, t. 21. fig. 5 \ 

 Lactica tibialis, Clark, Journ. of Ent. ii. p. 396 2 . 

 Lactica violaceipennis, Dej. Cat. 3rd ed. p. 413 3 . 



Eab. Mexico 2 . — Brazil 1 3 . 



Clark says that he has received this species from Mexico ; I have never seen any 

 specimens from that locality. On account of the specific name tibialis having already 

 been used by Olivier for a species of the same genus, I propose to alter Mr. Baly's name 

 to the older one of Dejean. 



33. Lactica binotata. (Tab. xvil. fig. 3.)
