Horn.] 572 [April 19, 
two rows of slightly elongate coarse punctures, each distinct. Body beneath 
rather coarsely punctured, first abdominal segment more coarsely than the 
others. Legs rufous. Length .08 inch ; 2 mm. 
This species and the preceding are closely allied, but the 
present has a better defined thoracic concavity. The apical 
margin is also more distinctly thickened. 
Occurs from District of Columbia to Florida. 
L. pusillus Lec. New Species, 1863. p. 67 ; laqgueatus Lec. Proc. Acad. 
1866, p. 368. 
Oblong-elongate, depressed, brownish or piceous, opaque, sparsely pubes- 
cent. Head sparsely punctulate and with a crescentic impression on each 
side. Thorax longer than wide, slightly narrower posteriorly, sides 
straight, margin entire, hind angles obtuse, apical margin thickened except 
at middle, and forming hook-like elevations surrounding the ends of obtuse 
carine which limit the broad median impression of the thorax, surface not 
densely punctured. Elytra slightly wider than the thorax, depressed varia- 
bly but rather strongly costate, outer intervals biseriately coarsely punc- 
tate and also very finely punctulate. Body beneath moderately densely 
punctulate. Length .10-.12 inch ; 2.5-3 mm. 
The elytral sculpture is variable as far as the coste are 
concerned. The following forms occur: 
pusillus Lec. type. Sutural interval feebly elevated, third interval 
feebly elevated at base, gradually becoming obsolete, fifth interval strongly 
elevated, seventhand margin less elevated than the fifth. Interval external 
to the fifth coarsely biseriately punctate, between the fifth and suture 
punctured at base, gradually becoming obsolete towards the middle. 
laqueatus Lee. type, differs but little from the above except that the 
third interval is still less elevated and the coarser punctures less evident. 
Specimens from Vancouver have the coarse punctures in the 
interspaces between the fifth interval and the suture continued distinctly to 
the apex. 
Occurs from Florida to Arizona and Vancouver. 
Tribe II]. COLYDIINE. 
Antenne capitate, retractile, inserted usually under a frontal margin at 
a short distance in front of the eyes. Head horizontal, eyes coarsely granu- 
lated, feebly prominent. Anterior coxee small, moderately separated by a 
slightly elevated prosternum, the cavities closed behind, except in Aglenvws. 
Middle coxee moderately distant. Posterior transverse narrowly separated. 
Metasternal side pieces variable in width, or even concealed. Abdominal 
segments gradually decreasing in length, the fourth shorter than the fifth. 
Tarsi moderately long, the first joint as long or longer than the next two 
together, the three longer than the fourth.
