If I have correctly determined this species, it chiefly differs from C. multistigmosa in 

 being generally smaller, less parallel, and with shorter thorax. The apex of the 

 abdomen appears to be slightly notched in the middle, and differs only slightly from 

 the female of C. multistigmosa ; the male is, however, easily distinguished by the 

 apical segment being more impressed and punctured in the middle, with the apical , 

 emargination rather deeper and narrower, its edge appearing blunt and not sharply 

 defined. Our two examples have the elytra obscure purple. 



33. Chrysobothris modesta. 



Prsecedenti affinis et simillima; differt tamen clypeo acute inciso ; fusco-senea, confertim punctata, elytris 



maculis cuprascentibus ornatis. 

 Long. 5^-6-i- lin. 



Hab. Mexico, Huetamo and Tacambaro in Michoacan (Hbge). 



As one of the characters by which C. octocola maybe separated from C. multistigmosa, 

 Dr. Horn (I. <?.) mentions that the emargination of the clypeus is " rounded at the 

 bottom." This applies to the male example (with green head) from Alamos, and to 

 the female from San Luis Potosi recorded above. Six specimens from Michoacan, 

 which I at first believed to be C. octocola, have the clypeus triangularly incised as in 

 C. multistigmosa. They cannot, however, be regarded as C. multistigmosa as they have 

 the short thorax, less acuminate elytra, and sexual characters of C. octocola ; I am 

 compelled, therefore, to separate them as a distinct species. The males do not present 

 any difference in the coloration of the head.

I see no reason for doubting that this is the species described under the name
