CEIMISSA.— DIBOLIA. 357 



in most of the specimens, which show the same sculpturing as those described by Von 

 Harold; whether the varieties with a partially red or piceous thorax are referable 

 to the present or represent other species, I am unable to say ; at all events none of 

 those before me agree quite with either of those described by the author of the genus. 



Section II. Thorax without transverse groove ; tibice and claws simple. 



a. Anterior coxal cavities open. 



This division comprises all those species of Halticinse which combine with a non- 

 impressed or grooved thorax, tibiae which show no emargination at their apex, and 

 simple or not swollen claw-joints. I follow the arrangement of Yon Harold in his 

 descriptions of South-American Halticinse.

The only species belonging to this genus is one of the largest of the Halticinse, and 

 has hitherto not been recorded from Central America ; it is a robust insect, and scarcely 

 typical of the present family, inasmuch as its posterior femora are scarcely more 

 incrassate than the others, and the general shape resembling rather that of a species of 

 Boryphora than one of the Halticinse, and there is no doubt that the insect represents 

 one of those intermediate forms whose classification is subject to different opinions in 

 the minds of naturalists.

The single specimen obtained in the State of Panama scarcely differs from the 

 Colombian specimens contained in my collection, except to a slight degree, no doubt 

 attributable to local variation.

 N. A. p. 354. 

 Bibolia is a genus comparatively easy of recognition on account of the long and 

 generally deeply emarginate spur at the end of the hinder tibiae, as well as by the 

 anterior prolongation of the prosternum covering to some extent the lower parts of the 

 mouth. Species of Bibolia are found in Europe, Australia, and in North and South
