CHRYSOBOTHEIS. 41 



20. Chrysobothris foveata. 



Lata, depressa, nitida, senea ; thorace transverso, postice angustato, medio profunde sat late impresso, utrinque 

 foveis tribus impressis ; elytris subtiliter punctulatis, marginibus crebre sat rugoso-punctatis, singulo basi 

 bifoveato, ante medium fovea rotundata sat magna, altera post medium prope marginem impressis, postice 

 prope suturam costa sat elevata ; corpore subtus viridi-seneo, bic et illic cupreo tincto, segmento ultimo 

 apice bisinuato ; tarsis cyaneis. 



Long. 7 lin. 



Hab. Mexico, Zacatecas {Brit. Mus.). 



This species somewhat resembles C. guatemalensis, but is relatively broader and more 

 shining. In C. guatemalensis there is on the forehead a finely punctured transverse 

 spot bounded below by a smooth elevated line ; in C. foveata this spot is less distinct, 

 and is bounded above by a smooth line. In C. foveata there is a very short elevated 

 line on the vertex that is not present in C. guatemalensis ; in this respect it approaches 

 C.femorata. The punctuation on the vertex is closer than in C. guatemalensis, but not 

 so close as in C. femorata. The thorax is not very closely punctured on the disc, but 

 closely and coarsely so on the sides ; the median impression is deep, broadest behind, 

 and on each side of it are two deep fovese, with a third less distinct one near the 

 anterior angle. The surface of the elytra is very uneven ; the basal foveae are well 

 marked, the inner one coppery ; the impression on the disc is rather large and round, 

 punctured but not rugose, partly coppery ; the posterior impression is smaller and more 

 lateral ; the costa near the suture behind the middle is sharply defined, slightly sinuous ; 

 the space between the costa and the suture nearly smooth ; outside the costa the surface 

 is longitudinally impressed, and the margins below the shoulder are also impressed ; and 

 parallel with the apical margin is a ridge, which separates the comparatively smooth 

 dorsal surface from the lateral rugose margin.

This species is somewhat variable, both in size and form, and some specimens are 

 difficult to separate from the North-American €. femorata, Oliv. ; it is, however, 

 generally rather shorter and broader than that insect. No doubt the specimens of
