DIABEOTICA 551 



at the base, two similarly-shaped spots near the apex, and a transverse band at the middle (neither of 

 these marks touching the sutural or the lateral margins), black ; legs testaceous. 



Hal. Mexico, Cordova, Orizaba {Salle), Jalapa (Hoge). 



This species is of a very broad, flattened shape, and the abdomen in the female is 

 greatly inflated ; all the structural characters peculiar to the genus are present. In 

 the variety the anterior black elytral spots are confluent with the band, leaving only a 

 small fulvous spot between them. 



We figure a specimen of the variety from Jalapa. 



112. Diabrotica suffriani. (Tab. XXXII. fig. 3.) 



Black ; thorax fulvous, without depressions ; elytra testaceous, a transverse band at the base, another at and 

 a third below the middle, as well as the apex of each, black ; femora fulvous. 



Length 3 lines. 



Head without punctures, the clypeus with a distinctly raised central ridge ; antennas black, half the length of 

 the body, the basal joint sometimes testaceous at the apex, the third joint twice the length of the second ; 

 thorax but slightly broader than long, fulvous or navous, entirely impunctate, and without depressions ; 

 scutellum black; elytra scarcely visibly punctured (even under a strong lens), testaceous, a narrow trans- 

 verse band at the base extending downwards a little distance along the suture, a transversely subquadrate 

 band at the middle, a similar band of less regular shape near the apex, and the apex itself, black; 

 underside black ; femora fulvous, the knees, tibiae, and tarsi black. 



Hob. Mexico, San Isidro (Roge). 



In the elytral pattern and colour this insect resembles D. albo-signata of the first 

 section ; but differs in the want of thoracic depressions, the longer third joint of the 

 antennee, and the entirely black under surface. The elytral bands do not extend quite 

 to the lateral or sutural margins, with the exception of the one at the base, which is 

 common to both elytra, but also abbreviated at the sides ; the third band is of a dentate 

 shape as if composed of two spots joined together. 



113. Diabrotica figurata. (Tab. XXXII. figg. 14 ; 15, var. b.) 



Subdepressed, slightly widened, black, the antennae fulvous ; thorax testaceous, bifoveolate ; elytra finely and 

 sparingly punctured, testaceous, each with a spot at the base, another at the middle, and a third near the 

 apex, black ; legs testaceous. 



Var. a. The elytral spots more or less connected laterally : the abdomen testaceous. 



Var. 6. The elytra black, the sutural and lateral margins narrowly testaceous. 



Length 2-2-i- lines. 



Head black ; antennae fulvous, the basal joint pieeous, the third joint twice as long as the second, the other 

 joints rather short and robust in the female, more elongate in the male ; thorax twice as broad as long, 

 the sides nearly straight, the surface impunctate, with a small fovea on each side, fulvous or testaceous ; 

 scutellum black ; elytra rather flattened, remotely and indistinctly punctured, testaceous, with variable 

 black markings — sometimes with a spot at the base, another at the middle, and a third near the apex, 

 sometimes with an elongate stripe at the sides from the base to the middle, the stripe deeply hollowed or 

 emarginate on its inner side, and a transverse spot near the apex, and sometimes black, with the margins 

 narrowly testaceous ; legs testaceous.

 None of the elytral black bands extend to the sutural or lateral margins ; in some
