CHEYSOBOTHEIS. 47 



C. multistigmosa. It is common at Oaxaca ; and the elytra being described as parallel, 

 or nearly so, at once points to this insect. 



The male appears to be dimorphic : numerous examples from various parts of 

 Mexico and one from Salvador have the antennae broad, compressed, and coppery, with 

 the third joint at its apex as broad as its length; other specimens from the same 

 localities have the antennae comparatively narrow, with the third joint elongate, scarcely 

 widened at its apex. 



I have not seen an example of the form with broad antennae from the United States ; 

 and as Dr. Horn (I. c.) does not mention it, I presume it does not occur there. 



35. Chrysobothris lateralis. (Tab. III. fig. 20.) 



Eloagata, parallela, obscure asneo-cuprea ; capite crebre ptmctato, parce pallide piloso, guttis duabus parvis 

 nitidis parum elevatis notato ; tborace transverso, quam elytra paullo angustiore, basi parum angustato, 

 lateribus rufo-eupreis ; singulo elytro basi foveola parva, secunda ad medium, duabus post medium vix 

 impressis lsete, rufo-eupreis.

The head is somewhat flattened in front, and closely punctured ; with two small 

 smooth spots below the middle, and another on the upper part of the face, from which 

 proceed two short oblique, often inconspicuous, lines. The thorax is moderately finely 

 punctured, the punctures separated from each other, on the sides as well as on the disc. 

 The elytra have a slightly asperate punctuation on the base and margins, but fine on the 

 disc, the punctures on the disc distinctly separated from each other ; the first costa is 

 only distinct in the apical third, and curved away from the suture before the apex ; and 

 there is a very short costa below the posterior red spots, and a short sublateral one. 

 Presternum densely punctured, clothed with greyish-white pile, which is more dense in 

 the male than in the female. Abdomen with whitish pubescence at the sides, finely 

 punctured in the middle, the apical margins of the segments smooth and steel-blue ; 

 the apical segment in the male slightly emarginate (Tab. III. fig. 20 a), in the female 

 slightly notched (fig. 20 5).

The specimens received from the late Mr. Morrison with this name differ from 

 C. lateralis in having the thorax a little broader, more rounded at the sides, more 

 pubescent, and more coarsely and (consequently) closely punctured. The elytra are 

 more uniformly and more strongly punctured, and there is only one impression behind
