transverse black bands; the thorax is testaceous, with two small black spots. An 

 example from La Parada is figured.

Diabrotica jansoni, Jac. P. Z. S. 1878, p. 994 \ 

 Hab. Nicakagua, Chontales (Janson 1 , Belt). 



This species probably ought to find its place in some other genus, as, on further 

 examination, the tibiae prove to be without spines. The insect is of large and robust 

 shape; the elytra are fulvous, with the posterior portion dark blue, this colour 

 sometimes not extending quite to the apex. 



f. Elytra testaceous, with small black spots. 



125. Diabrotica femorata. (Tab. xxxii. fig. 8.) 



Black ; thorax fulvous, without depressions ; elytra finely punctured, fulvous, the suture below the base, and 

 six spots (2 . 2 . 2) on each, black ; abdomen and the base of all the femora fulvous. 



Length 3 lines. 



Head black, impunctate ; antennae nearly as long as the body, black, the three basal joints fulvous below, the 

 third joint more than twice the length of the second ; thorax subquadrate, scarcely broader than long, 

 narrowly margined at the sides, the latter slightly rounded at the middle, the surface smooth, impunctate, 

 and without depressions, bright fulvous ; scutellum black ; elytra finely and not very closely punctured, 

 rather convex and a little widened posteriorly, slightly stained with reddish-fulvous, darker than the 

 thorax, the anterior third of the sutural margin, a subquadrate spot at the shoulder, a small spot near the 

 scutellum, two spots at the middle, placed transversely, and two others below the middle, black. 



Hab. Mexico, Las Peras {Salle). A single specimen. 



126. Diabrotica v-nigrum. (Tab. XXXII. fig. 18.) 



Pale flavous, the head black, the antennse fulvous ; thorax without depressions ; scutellum black ; elytra very 

 strongly and closely punctured, the suture narrowly, a A-shaped mark at the shoulder, and a somewhat 

 similar mark below the middle, black. 



Length 3 lines. 



Head black, the labrum piceous, the mandibles obscure testaceous ; antennse fulvous, the third joint twice as 

 long as the second, but distinctly shorter than the fourth ; thorax twice as broad as long, pale flavous, 

 impunctate, and without depressions ; scutellum black ; elytra very strongly punctured throughout, pale 

 testaceous, the suture narrowly, a short stripe connected with a transverse spot near the shoulder, and 

 another somewhat similar mark below the middle, black ; under surface and the legs flavous. 



Hab. Mexico, Jalapa (Hoge). 



A single specimen. D. v-nigrum will be known amongst its allies by the strong punc- 

 tuation, and the rather peculiar markings, of the elytra. 



127. Diabrotica septem-punctata. (Tab. XXXI. fig. 23.) 



Greenish-testaceous, the scutellum and the breast black ; thorax with two foveas, rugosely punctured ; elytra 



closely rugose-punctate, each with seven small black spots (1.1.2.3). 

 Length 3-3| lines. 

 Head with a deep fovea, the vertex with a few fine punctures ; antennae half the length of the body, entirely
