196 PHYTOPHAGTA. 



Easily distinguished by the entire absence of any small elytral spots. The general 

 colour is a dark greenish; the thorax has a small fovea at each side; the elytra have 

 the usual elongate shoulder-spot, and- the suture is widened before the middle, sending 

 off two small spots at right angles behind the middle. Amongst twenty-six specimens 

 two only are before me, in which two or three small spots are placed near the lateral 

 margin behind the middle ; generally there is only the spot at the shoulder present. 



2. Calligrapha diversa. (Tab. X. fig. 15.) 



Chrysomela diversa, St&l, Diagn. 1859, p. 324 x ; Monogr. Chrysom. Amer. p. 274 \ 



Hab. Mexico 1 2 , Etla, Juquila, Oaxaca, Cuernavaca, Guanajuato, Jalapa, Cerro de 

 Plumas (Salle, Edge); Guatemala (Salle), Duenas, Zapote, Capetillo, Purula (Champion) ; 

 Nicaeagua, Chontales (Belt) ; Costa Kica (van Patten). 



In the type from Mexico the green suture of the elytra is divided or split below the 

 base into a thin branch, pointing outwards; a row of five spots runs straight and 

 parallel with the lateral margin, leaving the latter entirely without any spots from base 

 to apex, which is one of the characteristic features of this species ; the position of the 

 spots is shown in the figured specimen from Juquila. In all the Guatemalan specimens, 

 with a single exception, the suture is not split as in the type, but extends to nearly the 

 basal margin, in which respect it resembles closely G. simillima from Venezuela, a 

 species which is doubtless only a variety of the present form ; the other elytral spots in 

 the Guatemalan insects are also placed somewhat closer, and are of larger size ; but 

 this character sometimes varies, and I cannot consider it of specific value, the position 

 of the spots and all other characters being identical. 



3. Calligrapha geographica. (Tab. X. fig. 18.) 



Chrysomela geographica, Stal, Diagn. 1860, p. 462 l ; Monogr. Chrys. Amer. p. 276 2 . 

 Hab. Mexico 1 2 , Cosamaloapam, Playa Vicente (Salle). 



There is very little difference between the present and the preceding species ; the 

 head and thorax are rather more closely punctured ; and the markings of the elytra, 

 although similar, are more closely placed ; the sutural design is broader ; and a thin 

 dark line composed of several spots runs parallel with the lateral margin, this part in 

 C. diversa showing no trace of any markings. This species seems to be entirely confined 

 to Mexico. 



4. Calligrapha consputa. (Tab. X. fig. 17.) 



Chrysomela consputa, Monogr. Chrys. Amer. p. 275 x ; Diagn. I860, p. 462 ". 

 Hab. Mexico, Oaxaca 1 2 , Panistlahuca (Salle). 



In this species there is again a nearly spotless narrow lateral margin of the elytra,
