DIABEOTICA. ^ 



it agrees in every way with the specimens from Nicaragua and the State of Panama. 

 D. cinctella varies in size from 1 to 1J line. 



102. Diabrotica hirta. (Tab. xxxil. fig. 16.) 



Testaceous, the head black, the antenna, tibia, and tarsi, fuscous ; thorax quadrate, bifoveolate ; elytra black, 

 closely punctured, sparingly clothed with whitish hairs, the lateral and apical margins, and a spot at the 

 middle of each, testaceous. 



Length 2^ lines. , 



Head impunctate, with a central fovea, the frontal tubercles nearly obsolete ; clypeus with a distinct central 

 ridge • labrum black, impressed with four punctures ; antennae more than half the length of the body, the 

 basal joint testaceous, the following seven joints fuscous or piceous, the terminal three joints obscure 

 fulvous; thorax quadrate, not broader than long, testaceous, the sides nearly straight, the surface very 

 minutely punctured, with two small fovese; scutellum piceous; elytra rather flattened and parallel, very 

 closely and finely punctured, with rather long and scattered stiff pubescence, the disc black and with a 

 central small transverse pale yellowish spot, the lateral margins narrowly, and the apices more broadly, 

 flavous ; underside and femora testaceous, the breast obscure piceous. 



Hob. Costa Rica, Volcan de Irazu (Bogers). 



A single specimen, resembling in its coloration D. cinctella, but larger and with the 

 elytra distinctly pubescent ; the third joint of the antennse is more than twice the 

 length of the second. 



d. Elytra metallic or Mack, the lateral margins and a transverse central 



band flavous. 



103. Diabrotica cruciata. (Tab. xxxil. fig. 2.) 



Black, the apical joints of the antenna,, and the thorax testaceous; thorax transversely depressed; elytra, 

 testaceous, finely punctured, an elongate subquadrate band extending to the middle, and a transverse 

 patch below the middle, dark metallic blue ; legs testaceous. 



Oretng^patuei shape ; the head impunctate, black; the antenna rather more than half the length of the 

 body the third joint twice as long as the second, the four lower joints more or less stained with fulvous, 

 the four or five following ones piceous, the apical joints testaceous; thorax rather more than twice as 

 broad as long, the sides distinctly constricted at the base, the surface impunctate, flavous or testaceous, 

 with a rather deep depression extending nearly across the entire disc; scutellum flavous or piceous; 

 elytra very closely and finely punctured, the dark bluish portion interrupted below the middle by a trans- 

 verse flavous band and by the very narrow flavous sutural and slightly broader lateral margins (the 

 flavous pattern in the shape of a reversed cross). 



Hal. Guatemala, San Isidro, Zapote, Teleman (Champion)', Salvador (mus. 

 Stuttgart). 



Allied to D. adonis, Baly, and several other species in regard to the elytral pattern; 

 but differing in the darker portion being interrupted on all sides, forming an elongate 

 subquadrate band anteriorly and a large oval spot below the middle. 



A specimen from San Isidro is figured.
