216 PHYTOPHAGA. 



rupted. The underside and legs also vary from piceous or fulvous (immature?) to 

 greenish black. A specimen in the collection of M. Salle, and labelled by Sturm 

 C. amama, proves his C. amcena to belong to the present species, and not to Z, guttati- 

 collis, as given in Gemminger's catalogue.

I have not seen any species agreeing with the author's description, who compares the 

 type to Z. lepidula, although the latter has no elytral stripes, except the sutural one, 

 the present species being described as having three on each elytron, in which it would 

 agree with Z. stall, Jac. The direction of the stripes in the latter species, and the 

 want of any spots, will prevent it being mistaken for Stal's species.

As already mentioned before, C. amoena, Sturm, is not a synonym of this species, with 

 which I am not acquainted, but refers to Z. conjuncta, Rogers.

In this species the small elytral spots are placed parallel with the sutural and lateral 

 margins, leaving the disk of the ground-colour ; but often a number of small spots occupy 

 the apex, and those near the lateral margin are confluent and form a longitudinal 

 narrow band of variable length. The species is of a rather elongate shape. 



20. Zygogramma morbillosa. (Tab. xil. fig. 17.)

Specimens of this species, named by Stal, are contained in Mr. Baly's collection, a 

 few others in that of M. Salle. The description given by the author is rather unsatis- 

 factory, inasmuch as he says nothing about the position or number of the elytral spots, 

 so that it is almost impossible to recognize the species without the type. The insect is 

 of a very convex shape, with the elytra of a more or less metallic golden hue, the latter 

 colour occupying, however, but little of the disk, on account of the large-sized subcon- 

 fluent spots. Of these a large round one is situated near the scutellum, and often
