212 PHYTOPHAGA. 



I am unable to find any such name amongst the species Stal has described, and must 

 attribute the statement on the label of the specimen to an error.

7. Zygogramma mexicana. (Tab. xn. fig. 7.) 



Obscure piceous or aeneous ; the last five joints of the antennae black ; elytra testaceous, the suture, an elongate 

 shoulder-spot extending to the former, two spots near the scutellum, another below the middle near the 

 suture, and twelve or fifteen smaller ones placed in irregular rows from the middle to the apex of each 

 elytron obscure seneous or piceous. 



Var. Head and thorax dark greenish seneous ; elytra with the shoulder-spot shorter and not extending to the 

 suture ; the spots below the middle less numerous. 



Length 2f-3| lines. 



Head very finely punctured ; antennae with the last five joints thickened and transversely shaped. Sides of the 

 thorax much rounded anteriorly, the anterior angles produced, surface, finely and closely punctured at the 

 middle, the sides strongly punctate : scutellum rather elongate, triangular. Elytra with two rows of 

 punctures near the suture, limiting the dark band placed there ; this latter protrudes in a thin branch at 

 each side of the suture to nearly the base, and is slightly widened near the apex; three spots of 

 irregular shape, but larger than the rest, are placed near it, one before, one at, and the third below 

 the middle ; the second of these spots is either connected with the elongate shoulder-spot or is free ; a 

 small spot, sometimes attached to the first sutural one, is also placed near the scutellum ; the rest of the 

 disk of each elytron is occupied by two or three very irregular rows of small spots, from ten to sixteen in 

 number ; the lateral margin is entirely without spots, but has an impressed dark line running parallel 

 with it; elytral epipleurse, as well as the underside and the legs, obscure seneous or dark fulvous with a 

 metallic gloss. 



Eab. Mexico, Ventanas, 2000 feet (Forrer). 



Four specimens of the present species, which is closely allied to Z. piceicollis, are 

 before me ; it differs from the latter in the greater number of spots, which are placed 

 in semiregular rows below the middle of the elytra ; in the place of the band which 

 accompanies the extreme lateral margin from the middle to the apex in Z. piceicollis, 

 a dark impressed line runs near the lateral margin. The thorax in the present species, 

 also, is much more transverse and greatly rounded anteriorly, which is not the case 

 in the allied insect. In the present one the shoulder-spot is often divided into two, 

 but in one instance these spots are not the same on both elytra ; the dark line parallel 

 with the lateral margin, however, is present in all specimens. 



8. Zygogramma lemur. (Tab. XII. figg. 8, 9.) 



Calligrapha lemur, Stal, Diagn. 1860, p. 460; Monogr. Chrys. Amer. p. 246 1 . 

 Hab. Mexico *, Juquila (Salle), Cerro de Plumas (Hoge). 



Of this species a specimen named by Stal, from the collection of Mr. Baly, and 

 several others from Mexico are before me. The insect seems to be subject to consi- 

 derable variation, as several specimens from Mexico, collected by Herr Hoge, show : 

 these are of an obscure piceous colour, as well as the elytral markings, the latter being 

 very dark greenish in the type. In its elytral designs the species is very closely allied 

 to Z. piceicollis, especially some of its varieties; but on comparing the two forms 

 it will be seen that the sutural band in Z. piceicollis is of equal width, and extends very
