DIABKOTICA.

pale fulvous, the third joint twice the length of the second; thorax about one half broader than long, 

 closely and strongly rugose and punctured, with two deep fovea* on the disc, and an obsolete depression 

 near the anterior and posterior margins; scutellum black; elytra rather convex and broadly ovate, 

 sculptured like the thorax, each with a small spot at the shoulder, another near the scutellum, two about 

 midway near the lateral margin (placed transversely), and three below the middle (two of which are 

 situated near the suture and placed transversely, and the third a little lower down near the lateral margin), 

 black ; legs testaceous, the breast black. 



Hab. Mexico, Las Peras (SalU). 



The rugose upper surface of the thorax and elytra and the position of the elytral 

 spots will readily distinguish this species.

The thorax of D. mexicana should be described as having three, not two, fovea?, as 

 stated in the diagnosis 1 ; the third fovea being placed between the larger discoidal 

 depressions, but nearer to the base. The elytra are rugosely punctured, slightly 

 shining, and each with seven (sometimes only six) small black spots (2.3. 2). 

 The thorax has always two spots placed in front of the fovea?. A specimen from 

 Orizaba is figured.

Hab. Mexico 1 , Tepansacualco, Puebla, Guanajuato (Salle), San Juan del Rio, Tupa- 

 taro (Hoge), Michoacan (Flohr). 



In the elytral pattern this insect exactly resembles D. mexicana ; the elytra, however, 

 are less distinctly punctured and more shining, and have their sutural and lateral 

 margins rufous; and an extra dark fulvous spot is generally placed near the lateral 

 margin between the rows of spots. The thorax is of a darker fulvous tint than in 

 D. mexicana; and the tibia? and tarsi, as well as the upper edge of the femora, 

 are black. 



130. Diabrotica quinque-punctata. 



Testaceous; thorax deeply transversely foveolate; scutellum black; elytra finely rugose-punctate, each with
