379 THE AMERICAN NATURALIST. [VoL. XXXVI. 
This species is quite closely allied to C. pedalis, flaviscapus, 
glaber, and carinatus, but is distinct from all by the form of the 
antenne, axilla, postscutellum, and maculation of collar. 
Ecitonetes gen. nov. 
Head globose, with a deep longitudinal frontal depression. Ocelli in 
a triangle, small and close together. Eyes oval, one-half as long as head 
and one-half as wide as long, coarsely faceted. Antenne inserted on pro- 
jections near the base of the clypeus; ten- 
jointed in female, scape stout, one and one- 
half times as long as eye, pedicel one-half 
longer than first flagellar joint, slender. 
Antenna thickest at the seventh joint; 
last joint about one-third as long as scape 
and obtusely pointed at tip, equal in length 
to pedicel.  Maxillary palpi long, four- 
jointed, last joint somewhat swollen; man- 
dibles indistinctly bidentate. Thorax oval, 
h 
head, and without any furrows or grooves. 
Scutellum absent, or at least not separated 
from that part of the mesonotum which 
extends over the place usually occupied by 
ings Econ subapterus Ọ the scutellum. Metathorax produced into 

posterior angles; much reduced, sloping on the sides and narrowed behind. 
Wings very small, about as long as distance between posterior ocelli or 
length of third antennal joint, with a strong vein along the costal margin 
and three strong bristles on the apical front margin, each about as long as 
the wing. Abdominal petiole very short, the abdomen squarely truncate 
. at the base, where it is about as wide as the thorax. Abdomen oval, acumi- 
nate, with six visible segments, the first of which is as long as the rest 
together, second and third subequal, each about one-fourth as long as first. 
— Legs rather short, stout; femora, especially posterior pair, swollen; anterior 
and posterior tibial spurs well developed. First joint of all tarsi elongated 
and longer than the three following ; claws simple.
