Spathalium helios^ new species (Plate X, figs. 6 and 7.) 



Apparently quite distinct from the other forms of the genus, 

 being characterized by the great elevation of the prozonal section 

 of the pronotal disk, the acute spiniform projections of the caudal 

 margin of the pronotal disk and the strongly serrate character 

 of the dorsal carina of the caudal femora. The strigose eleva- 

 tions of the metazonal disk are similar to those found in *S. his- 

 pidum, but the other features given above are sharpl}^ differen- 

 tial.

Size medium: general form as usual in the genus: surface of head, pronotum 



and limbs rugose to tuberculate. Head with the occiput moderately ascending 



cephalad; interocular section of the vertex very broad, equal to twice the depth 



^ From "HXtos, the sun, in allusion to the radiating points on the caudal 

 margin of the pronotal disk.
