elytra would distinguish it from that species. Colonel Casey has 
recently described six species with five punctures in the discal 
thoracic series (Mem. Col., VI, p. 437), none of which can be 
identified with the above, either because of elongate antennal 
joints, elongate and parallel-sided thoraxes, or different elytral 
sculpture. 
Philonthus strigicollis n. sp. 
Form moderately slender, slightly fusiform. Color black; first! antennal 
joint entirely, bases of the remaining joints, the elytral suture and legs 
rufo-piceous. Head including the mandibles, one fourth longer than wide, 
oval, posterior angles rounded to the neck; eyes, moderate in size, much 
flattened, distant their own diameters from the base; coarsely punctate 
above and beneath, more closely above; front with a broad median smooth 
space, constricted between the eyes; antenne long and slender, all the 
joints longer than wide, terminal joint truncate at! apex. Thorax less than 
one fourth longer than wide, slightly narrower than the head; base as 
wide as the apex; sides just perceptibly arcuate; apex truncate, base 
broadly rounded; an irregular row of coarse punctures either side and 
some irregularly placed punctures on the lateral declivities; head and 
thorax finely and obliquely strigose either side; when held at a certain 
angle, the strige have the appearance of a dense and fine pubescence, 
which becomes altogether invisible when the angle is changed. Elytra 
slightly wider than the thorax at base, slightly wider than the head at 
the apex, about one fourth longer than wide and one fourth longer than 
the thorax; humeri rounded, sides slightly arcuate; elytra and scutellum 
moderately coarsely and closely punctate and pubescent. Abdomen finely 
and rather closely punctate at base, more sparsely and indistinctly at apex, 
especially at the middle; beneath more coarsely and closely punctate. 
Length 6-6.5 mm.; width 1.25-1.45. 2 d. 
Male,—anterior tarsi rather strongly dilated and spongy pubescent’ be- 
neath; sixth ventral with a deep triangular emargination, one half the 
width of the segment and as wide as deep, the edge narrowly membranous. 
This species belongs in section E of Dr. Horn’s synopsis of the 
genus; the head punctured beneath would place it with P. viri- 
danus. The thorax is said to be very slightly narrower posteriorly 
with the sides sinuate, and no mention is made of any strigillation 
of the head and thorax, which is very distinct and peculiar in the 
above described species.
