ICHNEUMON. 155 



segment is broad, and occupies more than two thirds of the surface, the other bands 

 are narrower. 



The antennae, except the scape and the two basal joints of the flagellum, are unfor- 

 tunately wanting in the single specimen before me ; the former is ferruginous in colour ; 

 the latter black, reddish beneath. The tegular, the tubercle below them, the sutures of 

 the pleurae, the mesosternum, the apex of the scutellum, and the postscutellum are 

 yellowish. The metanotum behind has a yellowish tinge. 



Compared with i". platyaspis, the present species has a longer and narrower abdomen, 

 the metanotum is not so much hollowed in the centre, the postpetiole is not longitu- 

 dinally striated, and the scutellum is much more convex ; the same characters separate 

 it equally well from I. maculipleuralis. The form of the areolet is nearly the same in 

 the three species.

Hah. Mexico (Salle). 



Head subbuccate, obscurely punctured, deeply excavated above the antennae, the exca- 

 vation smooth, shining, and divided in the middle. Thorax punctured. Scutellum 

 subconvex, but little elevated, smooth, shining, impunctate, the sides arcuate. Meta- 

 notum with the areae obsolete ; a short blunt tubercle on each side. Petiole smooth, 

 shining ; postpetiole punctured, a slight furrow along each side above. Gastrocceli 

 shallow, situated at a little distance from the base of the segment, transverse, and finely 

 punctured. Abdomen punctured, pilose ; apex bluntly acuminate. Coxae punctured ; 

 the long spur of the posterior tibiae reaching beyond the middle of the metatarsus. 

 Areolet 5-angled. The black on the vertex is rather obscure ; the two longitudinal lines 

 on the mesonotum are broad and extend from the scutellum to beyond the tegulse ; and 

 there is a curved black mark at the extreme base touching the pronotum. The colour 

 of the abdomen, compared to that of the thorax, is rather obscure, but this is probably 

 owing to accidental discoloration.

Hab. Guatemala, San Geronimo (Champion). 



Antennae a little longer than the abdomen, somewhat thickened beyond the middle 

 and compressed, the joints there broader than long ; the apex acute. Head buccate ; 

 cheeks full ; vertex obscurely punctured. Mesonotum obscurely punctured. Scutellum 

 convex ; the base broader than the apex, the latter subtruncated ; sides abrupt, and
