220 PHYTOPHAGA. 



in its elytral pattern to Calligrapha dislocata, from which the claws united at their base, 

 as well as the red legs and attennse, at once separate it. Although the marking is very 

 similar, the present insect has in addition the median marginal spot as well as the 

 shoulder-stripe, both of which are absent in the other insect. In regard to the punc- 

 tuation of the elytra, all the dark marks and stripes are regularly limited by rows of 

 punctures, as is the case particularly with species of the preceding genus. 



26. Zygogramma gracilis. 



Below obscure greenish piceous ; basal joints of the antennae and the legs dark fulvous ; thorax dark fulvous, 

 rugose-punctate; elytra light testaceous, closely and strongly punctate, the suture fulvous; a narrow 

 marginal and sutural line, two others at the disk and joined at their apex, and a short streak near 

 the scutellum greenish aeneous. 



Length 3^ lines. 



Head very closely punctured, dark fulvous, the base greenish aeneous; last five joints of the antennae thickened, 

 a little longer than broad. Thorax transverse, the anterior angles but little produced and obtuse, sides 

 slightly rounded, nearly straight at the base ; surface closely rugose-punctate at the sides, much more 

 finely and distantly punctured on the disk ; scutellum fulvous, triangular. Elytra not widened behind, 

 moderately convex, yellowish white, closely covered (especially near the sides) with irregularly distributed 

 piceous punctures ; the suture narrowly fulvous ; close to and parallel with it runs a narrow greenish line 

 from below the base to a little distance from the apex, at which place a short greenish stripe is attached 

 to the sutural margin; close to the subsutural line a small thin streak is placed obliquely from the base to 

 the first third of the elytra followed by two other equally thin lines, which run parallel with each other, 

 and join at a little distance from the apex ; their first or anterior half runs obliquely towards the suture ; 

 from there they follow a straight direction ; a fifth line, joined at the base to the preceding one, runs at 

 some distance and parallel with the lateral margin, the extreme edge of this latter being also of a dark 

 green metallic colour ; elytral epipleurse testaceous at the anterior half, the rest piceous. Underside 

 metallic greenish, with the abdominal segments more or less fulvous or piceous. Legs fulvous, the femora 

 stained with greenish aeneous ; claws joined at their base. 



Hdb. Mexico, Yolos (Salle). 



In the punctuation, and pattern of the elytra, this species is quite distinct from 

 any other in this genus. Only a single specimen is before me.

The only specimen from the coUection of M. Salle, which I have before me, and 

 which is figured, agrees so closely with Stal's type, which I have also for examination, 

 as well as with several specimens from the Amazons region in my collection, that I 

 must consider them all to represent one species. Stal himself has described six 

 varieties, showing the species to be a very variable one ; his type, from the collection 

 of Deyrolle, is larger than the other specimens before me, and differs from the Mexican 

 and other forms in having a greenish-blue thorax instead of a fulvous one, which is the 

 colour of the Mexican specimen ; but even here the lateral margins of the thorax are
