h. Elytra testaceous, with longitudinal black or blue strifes or posterior spots.

Diabrotica novem-maculata, Jac. P. Z. S. 1878, p. 995 \ 



Hab. Costa Eica \ Volcan de Irazu, Eio Sucio (Sogers) ; Panama, Volcan de Chiriqui 

 (Champion). 



In the elytral design and general coloration D. novem-maculata closely resembles 

 several species of the first section with short third joint to the antennae, notably 

 D. fulvicornis and D. hybrida. In D. novem-maculata the corresponding antennal joint 

 is, however, nearly twice the length of the second; the elytral spots are thicker, the 

 anterior sutural streak forming an elongate pointed triangle, and the outer spot below 

 the middle, as well as the one placed at the shoulder, is elongate and of equal length. 



140. Diabrotica lateritia. (Tab. xxxii. fig. 12.) 



Flavous, the head, breast, and tibia black ; thorax without depressions ; elytra closely punctured, flavous, the 

 suture, a discoidal and a lateral longitudinal stripe, and a spot at the shoulder, black. 



Length 3 lines. 



Head entirely black ; the frontal tubercles very distinct ; the vertex with a longitudinal groove ; antenna 

 piceous, the basal three and the apical three joints fulvous ; thorax subquadrate, slightly broader than 

 long, the surface rather convex, without any traces of depressions, impunctate, flavous ; scutellum black ; 

 elytra rather convex, very closely and distinctly punctured, a large subquadrate spot at the shoulder 

 connected with the similarly-coloured narrow basal margin, a narrow lateral stripe from the middle to the 

 apex, a shorter discoidal stripe, and the suture very narrowly, black. 



Hab. Guatemala, Purula (Champion). A single specimen. 



The short black stripe on the disc of each elytron commences in a line with the 

 lateral stripe, but is only about half the length of the latter ; the third joint of the 

 antennae is nearly three times as long as the second. 



i. Elytra metallic, unicolorous or margined with flavous. 

 1.41. Diabrotica flavifrons. (Tab. xxxii. fig. 22.) 



Black, the clypeus and the base of the femora flavous ; thorax finely punctured, with two depressions ; elytra 

 metallic blue or purplish, closely punctured, the interstices obsoletely rugose. 



Length 2 lines. 



Of narrow elongate shape ; the head bluish-black, opaque, with a narrow lightly-impressed central groove ; the 

 frontal tubercles and the clypeus flavous, the labrum black ; antenna slender, black, the third joint nearly 

 three times as long as the second ; thorax about one half broader than long, opaque, the surface finely and 

 obsoletely punctured, black, with two closely approached depressions on the middle of the disc ; scutellum 

 black ; elytra purplish-blue, finely and closely punctured, the interstices here and there obsoletely rugose ; 

 legs slender, the femora flavous at the base, the knees, tibia, and tarsi black. 



Hab. Mexico, Cordova (Salle). A single specimen.
