Celinius meromyze,n.s. [Plate II, Figs. 1 and 2.) Shining black ; 
legs reddish yellow; basal segments of the abdomen and basal joints 
of the antenne yellowish. The head is cuboidal, emarginate behind, 
smooth and shining above, with a few scattered gray hairs. A faint 
median furrow leads forward to the ocelli. The eyes are nearly 
circular, and the front is broadly and smoothly excavated between 
them, above the attachment of the antenne. Below the latter the 
head is finely punctured and rather closely set with yellowish gray 
hairs. The clypeus is simple, entire, convex in front; the labrum 
broadly emarginate, and with a shght median carina. The palpi 
are white. The mandibles are three-toothed at tip, reddish, except. 
at the apex, which is piceous. The antenne are long and slender, 
composed of thirty-one joints, the first of which is inflated obeoni- 
cal, the second is of about the same length and a truncated cone, 
the third very minute, the fourth the longest, bemg about three. 
times as long as wide. In width, the segments of the terminal part 
of the antenne are about equal to their length. They are marked 
with numerous fine, longitudinal ridges, and are densely pubescent 
throughout, except the two basal joints. 
The mesonotum is smooth and shining, provided with only a few 
sparse gray hairs, and is bordered by a line of coarse punctures, 
and divided by a Ye shaped line of punctures into three areas, the 
anterior of which is more pubescent than the other two. The sides 
of the mesothorax are smooth and shining, except for a submargi- 
nal row of coarse punctures and two or three small sunken areas, 
which are likewise punctured. 
The scutellum is carinate in the middle and bordered anteriorly 
and posteriorly by a transverse band of large irregular rugosities. 
In front of the posterior band and between the bases of the hind 
wings, is an elevated, shining, linear, transverse area, from the center 
of which a triangular smooth area extends forwards, with its basal 
angles reaching to the bases of the front wings. The metathorax 
is regularly convex, covered everywhere with sinuous rugosities, 
and sparsely beset with long gray hairs. 
The peduncle of the abdomen is partly smooth above, being 
marked with only a few longitudinal rugosities near its distal end. 
The remainder of the abdomen is smooth and shining, and more 
or less densely pubescent, the last four or five segments in the 
female being strongly compressed. 
The legs are all yellow, the posterior thighs and coxe being a - 
little darkened. The two anterior pairs of coxe are smooth and 
yellow, but the posterior pair is rugose, like the peduncle of the 
abdomen. Wings yellowish, highly iridescent, veins and stigma 
yellowish-fuscous. The middle humeral cell is triangular, acute 
externally, the posterior humeral linear. The radial cell is oval, 
pointed externally, the radial nerve being regularly curved. The 
recurrent nervure extends very obliquely backward. 
The male is similar to the female, except that it is somewhat 
smaller, and that the abdomen is not compressed, and the palpi 
and antenne are darker and considerably longer, containing about 
thirty-seven joints.
