CHRYSOBOTHRIS ROGAGUAENSIS. new gpecies 



Male. — Form rather broadly oblong and feebly convex, with the 

 surface subopaque; color aeneo-brunneus, with a feeble cupreous or 

 purplish tinge, the head more or less ornated with bright green, 

 which is more distinct on the epistoma, along the lateral margins and 

 antennal cavities, and sometimes with two small round spots on the 

 front ; antennae green at base, becoming reddish-cupreous toward the 

 apex; each elytron with three irregular foveae, a rather deep one at 

 basal lobe, an obsolete irregular one at middle divided by the second 

 costa, and a more distinct zigzag one near apical third, extending 

 between the second and fourth costae, the foveae are nearly con- 

 colorous, but in some specimens they are more distinctly aeneous or 

 cujDreous; beneath aeneo-brunneus, with a strong cupreous tinge at 

 the sides, becoming golden-green, with a strong cyaneous reflection 

 on the median parts and tibiae, the tarsi cyaneous. 



Head feebly convex, with the front triangular, the sides strongly ob- 

 liquely narrowed toward the top, and with three irregular transverse 

 carinae which do not extend to the lateral margins, and arranged as 

 follows : a very narrow sinuate one, broadly interrupted at middle, 

 and situated behind the antennal cavities, a broader, feebly arcuate 

 one on the front, and a narrow one on the vertex; surface coarsely 

 and irregularly punctate, the punctures more shallow and widely 

 separated on the front, becoming deeper and confluent on vertex and 

 along the eyes, sparsely clothed with fine long recumbent cinereous 

 hairs ; intervals finely and densely granulose ; eyes large, moderately 

 convex, top and bottom about equally rounded, and separated from 

 each other on the occiput by about the same distance as between the 

 antennal cavities; epistoma feebly and broadly arcuately emarginate 

 in front, the lobes on each side very broadly rounded; antennae 

 rather short, the third joint about as long as the following two joints 

 united. Pronotum strongly transverse, nearly two times as wide as 

 long, widest along middle, apex and base about equal in width ; sides 

 strongly obliquely expanded from anterior margin to apical fourth, 

 then parallel to basal third, except for a regular arcuate emargina- 

 tion, and finally obliquely narrow^ed to the posterior angles, which 

 are obtusely angulated; anterior margin broadly arcuately emargi- 

 nate, with only an obsolete median lobe; base strongly arcuately 

 emarginate on each side at the elytral lobes, the median lobe broadly 

 rounded and narrowly truncate in front of the scutellum; surface 

 feebly convex, with an obsolete longitudinal median sulcus, and with 

 two more or less distinct round depressions on each side of the mid- 

 dle, the posterior pair broader and more widely separated than the 

 anterior pair, there is also an irregular flattened depression on each 

 side along the lateral margin, finely and irregularly punctate, the 

 punctures widely separated on the disk, but becoming more confluent
