DIABEOTICA.— MICEOBEOTICA. 569 



surface distinctly and semiregularly punctured, each with a black spot at the shoulder, a slightly larger 

 one below the middle, and another spot common to both placed at the suture below the scutellum ; under- 

 side and legs testaceous, the tibiae and tarsi black. 



Eab. Nicakagqa, Chontales (Jans on). 



A single example. D. nigropicta should follow B.figurata in the arrangement here 

 adopted ; it is distinguished from its allies by the five elytral spots and their position. 



162. Diabrotica complicata. 



Ovate, subdepressed, black below ; head and antennae obscure piceous ; thorax testaceous, bi-impressed ; elytra 

 very finely punctured, testaceous, a broad longitudinal band of irregular shape from the base to the middle, 

 and a broad transverse band near the apex, black ; legs fulvous, spotted with black. 



Var. The anterior band of the elytra reduced to a spot. 



Length 2-2 1 lines. 



Head black at the vertex, the sides of the clypeus more or less testaceous ; antennae half the length of the 

 body, obscure fulvous or pale piceous, the third joint twice as long as the second ; thorax transverse, 

 impunctate, the disc with two foveae ; scutellum piceous, its apex broadly rounded ; elytra depressed, 

 rather widened posteriorly, very minutely and not closely punctured, the posterior portion nearly impunc- 

 tate, testaceous, with a broad longitudinal black band (narrowed at its middle and irregularly shaped) 

 extending from the base to the middle of the disc and followed at a short distance by a broader and more 

 regular transverse band not quite extending to the lateral margin ; the femora have a piceous spot at the 

 middle, and the tibiaa a spot at the base, the latter also being stained with piceous to a greater extent 

 near their apex. 



Eab. Mexico, Jalapa [Edge). 



Allied to D. figurata and D. dorso-signata, but differing in the pattern of the elytra 

 and other particulars ; the anterior elytral spot is very variable in shape and size and 

 occupies in some specimens the greater part of the disc. 



163. Diabrotica apicalis.

Diabrotica nigrocincta, Baly, Trans. Ent. Soc. Lond. 1886, p. 451 l . 

 Eab. Mexico, Teapa (Pilate x ). 



In speaking of the antennse, Mr. Baly describes the second joint as " more than half 

 the length of the third " : this is evidently a mistake and should be reversed, as the third 

 joint is never shorter than the second in Diabrotica. 



MICEOBROTICA. 



Body oblong ; antennae slender, filiform, the first joint elongate and the longest, the second not very short ; 

 thorax not broader than long, strongly narrowed at the base; elytral epipleurae continued below the 

 middle ; tibiae unarmed ; the first joint of the posterior tarsi as long as the following two joints together ; 

 claws bifid ; the anterior coxal cavities open. 



MicrobrOtica is principally distinguished from Diabrotica, which it resembles in 



biol. cente.-amee., Coleopt., Vol. VI. Pt. 1, December 1887. 4 d
