2. Botryocampe theocajysa, n. sp. 



Cephalis trilobate, half as long as the campanulate thorax, and one-third as long as the ovate 

 abdomen. Frontal lobes subspherical, scarcely half as long as the helmet-shaped occipital lobe. 

 Pores very small and scarce.

 Occipital lobe ovate, one and a half times as long as the two ovate frontal lobes, and three times 

 as long as the two subspherical buccal lobes. Collar septum with six distinct cortinar pores 

 (two anterior jugular, two middle cardinal and two posterior cervical, fig. 23).
