THE PAN-PACIFIC ENTOMOLOGIST 
Lypsimena tomentosa, new species 
Female: Form moderate sized, subparallel; integument reddish brown, pubescence 
pale brownish and gray, dense, appressed, obscuring surface, erect hairs almost absent. 
Head short, densely pubescent; median line shallow, becoming a suture on vertex; vertex 
short, moderately densely punctate, punctures obscured by pubescence; antennae 
slender, slightly longer than body, segments densely clothed with short appressed 
pubescence, basal segments with a few long suberect hairs internally which decrease in 
length toward apices, third segment longer than first, remaining segments gradually 
decreasing in length. Pronotum broader than long, sides broadly rounded, disk convex, 
rather coarsely, confluently punctate; pubescence appressed, obscuring surface, sides 
with several long erect hairs interspersed; prosternum narrow, coxal cavities closed 
behind; meso- and metasternum densely pubescent, punctures obscured. Elytra more 
than twice as long as broad; basal punctures rather coarse, dense, becoming obsolete 
behind middle; pubescence appressed, pale brownish, with white or gray pubescence 
suffused over disk away from suture, base, and apex; apices narrowly subtruncate. Legs 
short, femora gradually expanded toward apices; front tibiae with an internal sinus, 
middle tibiae with an external sinus. Abdomen minutely, densely punctate, very densely 
clothed with appressed pubescence; last sternite broadly subtruncate at apex. Length, 9- 
10 mm. 
Holotype female (Cornell University) and seven female paratypes from Ciudad Bolivar, 
Venezuela, 4-24 April, 1898, 2-24 May, 1898 (E.A. Klages). 
The very dense appressed pubescence which completely obscures the body surface 
will readily separate this species from other known Lypsimena. 
The only significant variation observed in the type series is in the amount and extent of 
suffused whitish pubescence on the elytra. This is almost absent in some individuals but 
quite distinct in others.
