LeConte.] 596 {| April 18, 
ternum not punctured, less dilated behind than in the other species, but 
with two short posterior striz ; metasternum with a deep impressed 
median line, smooth, with only a few scattered punctures behind. Length 
26 mm. ; .10 inch. 
Monroe, Michigan ; one specimen ; very different from the 
other species by the regularly oval form, scarcely narrower 
behind than before, by the peculiar punctuation of the elytra 
and by the impunctured sterna. The last joint of the maxil- 
lary palpi is nearly acute at tip, and does not appear emar- 
ginate from any point of view. 
The insect mentioned in the Florida list (ante p. 438) as 
Suphis nu. sp., on remounting, proves to be a very small 
species of Laccophilus, having the same form of prosternum 
as the others. It may be here conveniently described as: 
8. Laccophilus pumiilio. Ovate, pointed behind, not convex, im- 
punctured, rufo-testaceous, meso- and metasternum darker; elytra piceous, 
slightly iridescent, regularly narrowed behind, and not obliquely truncate 
at tip; abdomen without the distant fine oblique lines seen in the other 
species. Length 1.9 mm. ; .075 inch. 
Enterprise, Florida; one specimen. Very careful exami- 
nation shows in certain lights traces of two or three lines on 
the second ventral segment towards the sides, but these are 
the only evidences of the characteristic ventral sculpture of 
the other species. 
9. Gaurodytes leptapsis. 2 Elongate-oval, less obtuse than usual, 
black, with a slight bronzed tint, opaque, finely strigose with lines forming 
very elongate meshes ; base of antenne, palpi, front and middle legs tinged 
with piceous. Head less opaque than the prothorax, the sides of the latter 
are oblique, finely margined and scarcely rounded. Elytra with the usual 
rows of punctures indistinct. Beneath shining, finely reticulate, meso- 
sternum acutely emarginate, hind tibiz sparsely, coarsely punctured, mar- 
gined on the inner side, but without a very distinct row of punctures. 
Front and middle thighs distinctly, not densely punctured. Length 9.7 
mm. ; .88 inch. f 
Marquette, Lake Superior ; one specimen. This species is 
as elongate as G. parallelus, but less obtusely rounded, and 
is easily recognized by the peculiarily elongated meshes of 
the reticulation. The prosternum is obtusely carinate. 
10. Gaurodytes longulus. Elongate-oval, obtuse at each end, not 
convex, shining, smooth black, witha slight metallic gloss. Antenne, palpi
