A NEW SPECIES OF HALIPLUS 
By Edith W. Mank 
Lawrence, Mass. 
Some beetles, collected in July 1939 in Churchill, Manitoba 
by Mr. Albert L. Wilk, came into the hands of Dr. H. C. 
Fall and were mounted just before his death. He had ex- 
amined them and noted among them two possible new spe- 
cies, one a Hydroporus and the other a Haliplus. He 
mentioned to me particularly the Haliplus. This, I herewith 
wish to describe and name for him in recognition of his 
unfailing inspiration and help. 
Both Dr. P. J. Darlington, Jr. and Mr. J. B. Wallis have 
most generously given their time and assistance in prepar-

Haliplus falli n.sp. 
Holotype 9: Length 2.79 mm. Width 1.44 mm. In gen- 
eral form narrower and more parallel than longulus to which 
this species runs in the key to the Haliplids by Mr. Wallis. 
Head: Brownish yellow with posterior part dusky; mouth 
parts and antennae the same color as the front. Surface alu- 
taceous, making it duller than in such species as longulus. A 
punctate triangular area with base of triangle anterior, be- 
tween the antennae; also punctured areas in crescent shape 
around the eyes ; also on posterior darkened part of the head. 
Smooth area, shiny not alutaeeous, between the clypeus 
which is punctured, and the punctured area on the front. 
Width between the eyes half the entire width of the head. 
Head wider, as compared with the base of the pronotum, 
than in longulus. 
Pronotum: More yellowish than the head, with basal area 
dark. The dark area widest between the fairly long, deep, 
longitudinal plicae. Also darkened medially on the anterior 
edge. Surface very finely alutaeeous. Lateral margin nar-
