Ten examples are before me from Santa Rosa, and another from 

 Ecuador. I consider the form to be a variety of Sphecosoma 



angustatu/ii . 



Genus EPISCEPSIS Butler. 



EPISCEPSIS DODABA, new species. 



Head and thorax blackish brown, two crimson spots on the back 

 o!' the head; tegulse with small crimson spot laterally; fore coxae 

 crimson. Fore wing uniformly brown-black, slightly bronzy, the 

 veins eoncolorous. Hind wing black, semihyaline whitish in the cell 

 and below. Abdomen shining blue above, black at the base, the 

 three basal segments white-marked beneath in the male, entirely 

 black beneath in the female. Expanse, 32 to 34 mm. 



Santa Rosa, State of Vera Cruz, Mexico, August, 1906 (W. Schaus) ; 

 Orizaba, Mexico, September, 1906 (R. Midler). 



Tape.— Cat. No. 12938, U.S.N.M. 



Fifty-six examples are before me, including also the localities 

 Cordoba, Jalapa, and Coatepec, Mexico, and Aroa and Merida, 

 Venezuela. The species differs from Kpiscepsis inornata Walker in 

 the presence of a small crimson spot on the tegula. This spot varies 

 in size, and it is possible that the forms intergrade. 



EPISCEPSIS FRANCES, new species. 



Black-browm, the occiput with two crimson spots; a crimson mark 

 on the pleura below the tegulaa; fore coxae crimson. Fore wing 

 uniform brown-black, the veins eoncolorous; hind wing semihyaline

 the base, black below, the three basal segments white-marked. Ex- 

 panse, 27 nun.

 the inner vi\^c of the patagia across t he tegula to t he base of antenna.
