NEW CERAMBYCID BEETLES—FISHER 49 
middle of elytra, brownish or brownish black, except segments 1, 5, 
and 6, which are yellowish, sparsely clothed on underside with a few 
rather long, semierect hairs; segment 1 slightly expanded toward 
apex, three-fourths as long as third, which is twice as long as fourth. 
Pronotum distinctly wider than long, narrower at apex than at base, 
widest. behind middle; sides obliquely diverging from apical angles. 
to middles, strongly, arcuately expanded behind middles, strongly con- 
stricted near bases; disk moderately convex, narrowly, transversely 
grooved along anterior margin, broadly, transversely depressed along 
base, with a large, erect, conical tubercle (which is obtusely rounded at 
apex) on middle of disk; surface impunctate, clothed with a few 
inconspicuous, erect hairs. Scutellum transverse, deeply, longitudi- 
nally depressed at middle. 
Elytra distinctly wider than pronotum behind middle; sides par- 
allel from humeral angles to near apices, which are separately nar- 
rowly angulate; surface coarsely, densely punctate basally, the punc- 
tures becoming finer and sparser toward apices, sparsely clothed with 
short, inconspicuous, erect hairs, and each elytron ornamented with 
black as follows: A broad fascia at base with posterior margin angu- 
late, and a broad fascia at middle with the anterior and posterior 
margins crenulate, the fasciae not quite reaching the lateral margin. 
Abdomen beneath impunctate, with a few long, inconspicuous, erect 
hairs; last visible abdominal sternite broadly rounded at apex. Meso- 
sternum and metasternum coarsely, shallowly punctate, more densely 
pubescent than abdomen. Prosternum glabrous, transversely rugese. 
Length 11-12 mm., width. 3.5 mm, 
Type locality—Hamburg Farm, Costa Rica. 
Type and paratype.—U.S.N.M. No. 57672. 
Remarks.—Described from two females (one type). The type was 
collected at the type locality, July 19, 1925, by Ferdinand Nevermann, 
and the paratype was collected at Coronado, 1,400 to 1,500 meters, 
Costa Rica, May 15, 1925, by T. Assmann. 
The paratype differs from the type in having the antennae paler 
and the elytra ornamented with a large triangular black spot at the 
humeral angles and a black diamond-shaped spot along the sutural 
margins behind the scutellum. 
This species is closely allied to Oxylymma lepida Pascoe, but it dif- 
fers from the description given for that species in having the top of the 
head entirely black, the pronotum armed with a large conical tubercle 
on the median part of the disk, the elytra with a broad black fascia 
at the base or a black diamond-shaped spot behind the scutellum, the 
tips of the elytra more obtusely angulated, the last two abdominal 
sternites yellow, and in not having the tips of the elytra black.
