slightly longer than the eyes, tapering, apex blunt and broad, depressed 

 with very distinct lateral carinae; face concave; eyes elliptical ovate; 

 antennae with the basal joint about one-third the length of the eye. 

 Pronotum with the limbs inserted caudad of the middle; cephalic mar- 

 gin rotundate with a median truncation, caudal margin truncate, 

 lateral margins slightly constricted cephalad of the insertion of the 

 limbs. Mesonotum and metanotum fused, strongly impressed rugulose 

 dorsad, depressed. Abdomen somewhat compressed, carinate, sub- 

 equal, narrower than the meso-metathorax ;^^ supraanal plate sagittate; 

 ovipositor valves heavy, blunt, margins unarmed; subgenital plate 

 very slightly rotundato-truncate. Cephalic and median femora very 

 similar in structure, the cephalic pair slightly the larger. Caudal 

 femora slender, reaching nearly to the distal margin of the sixth 

 abdominal segment; caudal tibiae bearing twenty to twenty-one spines 

 on the external margins, twenty- two on the internal margins. 

 General color gallstone-yellow, the eyes dull greenish.

An immature specimen from Cautin, Chile (C. S. Reed; January, 

 1904; A. N. S. Phila.) I also refer to this species. It is a male, but 

 fully agrees with the type in all essential characters.

CephaloccEma sica (Serville).

 part of Campos Geraes, Brazil.] 



Sao Paulo, Sao Paulo, Brazil. September 1 and 7, 1900. (Adolph 

 Hempel.) [A. N. S. Phila.] Two males. 



These specimens have the subgenital plate more produced and elon- 

 gate than in Serville's figure, but otherwise they fully agree with this 

 species. 



" This condition may be due to the artificial compressing of the abdomen, 

 but it is very evident that the width is by no means as great as in the female of 

 occidentalis figured by Brunner (Verhandl. K. K. Zool.-Bot. Gesell., Wien, XL, 

 taf. V, fig. 10).
