ICHNEUMON. — (EDICEPHALTTS. 187 



very large and stout. Petiole smooth and shining, hollowed in the centre, contracted 

 in the middle, the apex aciculate ; postpetiole coarsely punctured, the middle bluntly 

 carinate on either side to near the apex. Gastrocceli transverse, indistinct. The second, 

 third, and the basal half of the fourth segments of the abdomen coarsely and longitu- 

 dinally punctured ; the apex shining and almost impunctate ; a transverse white mark 

 on either side of every segment (including the petiole), the marks becoming wider and 

 narrower as the apex is reached ; ventral surface white in the centre, the apical 

 segments banded with white. Areolet 5-angled, converging above. Hind coxse 

 strongly punctured. 



The following species has the general form (especially the thorax and abdomen) of 

 Joppa, but the antennae in the female are slender, and not dilated and compressed. The 

 punctuation of the thorax and abdomen varies, in intensity. Brulle places the species 

 in Joppa, Cresson in Ichneumon. Actually it is intermediate between these genera.

As the punctuation of the thorax and abdomen varies, I have no doubt that the 

 Cuban 1. breviventris is an aberration, as Cresson suspected. 



CEDICEPHALUS. 



(Edicephalus, Cresson, Trans. Am. Ent. Soc. ii. p. 27 ; Proc. Acad. Phil. J873, p. 129. 



This genus is chiefly remarkable for having the head " unusually large and swollen, 

 very broad behind the eyes, the occiput deeply emarginate," and the basal foveae on the 

 second abdominal segment " broad, transverse, and very deep." Cresson looks upon it 

 as only a subgenus of Ichneumon. All the described species are from Cuba and 

 Mexico.
