MIOLACHNOSTERNA, gen. nov. 
‘Body outline resembling that of Anomala. Pronotum short, the — 
base broadly, squarely truncate. Scutellum distinct, small. Sculp- 
ture fine, body hairy above. Pygidium uncovered. Legs moderately 
stout, hind tarsus, including the claws, nearly as long as the tibia, 
the first four joints subequal, rather slender, claws simple. 
Type.— M. tristordes, sp. nov. 
MIoLACHNOSTERNA TRISTOIDES, sp. nov. 
Plate 8, fig. 1-3. 
Outline, as preserved, ovate, somewhat pointed behind. Head 
not well displayed, apparently rather small, the vertex moderately, 
finely, and sparsely punctured. Prothorax finely, sparsely, and rather 
regularly punctate, clothed with long light colored hairs which do not 
interfere with a clear view of the sculpture. Basal truncation wide, 
equal to about three fifths of the greatest pronotal width. Scutellum 
punctured like the pronotum. Elytra strongly narrowed posteriorly, 
confusedly, and a little more coarsely, and much less deeply punctured 
than the prothorax, similarly clothed with hairs, the punctures spaced 
about as on the pronotum. Exposed pygidial surface obscurely 
punctate. Hind tibia hairy. Length, to tip of elytra, 7.50 mm. 
Described from one specimen. ; 
Type.— No. 2,569 M. C. Z. Florissant, Col. (No. 13,668 S. H. 
Scudder Coll.). 
In sculpture and vestiture this insect is not very different from 
the recent Lachnosterna tristis, but the absolutely simple claws pre- 
clude the reference to this genus. The basal pronotal truncation 
is much more pronounced than in Lachnosterna. The safe course 
seems to lie in the erection of a new genus. The only point not 
alluded to in the description, which calls for remark, is the appear- 
ance of a long rather stout spine on the poorly preserved front tibia, 
and while I have shown this in the figure and detail I am by no 
means certain of its being a true character. I have presumed this 
species to be a melolonthide and suggest that it be placed near 
Lachnosterna for the present.
