teeth on each side, its wing-covers with two or three slight elevated lines, its antenn:e 
searcely as long as the body, and its color chestnut red, darker anteriorly. 
Larva.—Described while alive. Body cylindrical, not flattened, the 
segments very distinct, as the sutures are deeper than usual; head 
moderately broad; prothorax large and broad = 
and rather long, being 9™™ broad and 45™™ long ; 
surface rough on the posterior two-thirds. On 
each of the Ist to 7th abdominal segments is a 
transverse oval, cylindrical fleshy area, each with 
three transverse folds, the area on the 7th ring 
being nearly twice as long (antero-posteriorly) as 
that on the first; the areas becoming longer and 
narrower; i.¢., more rounded, going backward 
towards the 7th segment; the end of the abdo- 
men smooth and shining; each thoracic segment 
with a pair of slender 3-jointed feet. Length, 
35™™ (14 inches). Two dozen or more were taken 
May 26 by Mr. Calder and myself from a very 4, 7 The lesser Prionus: 
soft, rotten pine stump; up to June 24 they had Natural size.—After Riley. 
not pupated in confinement, but by the 5th to the 8th of July one of 
them became a pupa. 
Pupa.—Antenne bent near their end at right angles and laid across 
the end of the elytra, the latter reaching to the middle of the hind 
tarsi. End of the abdomen terminates in.a singular ruffle-like expan- 
sion, armed on the edges with stout spines. Hind tarsi reaching to the 
middle of the 5th abdominal segment. The body considerably curved. 
Maxillary palpi extended well beyond the end of the mandibles. Pro- 
thorax with a broad-based spine on the side. The projecting parts of 
the abdominal segments with fine spines, and segments 5 to 5 with a 
pair of transverse, thin, dark-brown, chitinous patches. Length, 50™™. 
Mr. Calder has also fotnd the fully grown larve in August in maple 
logs at Warwick, R. I.,and in the rotten wood of another 
deciduous tree. So that it appears that this beetle lives 
indifferently in the soft, decayed logs or stumps both of 
hard and coniferous trees. 
27. PRIONUS EMARGINATUS Say. 
Probably injuring shade or timber trees in Utah, a dark 
brown beetle of the following appearance : 
Body castaneous; head, thorax, and breast covered with long 
yellowish ferruginous hair; antenne fourteen-jointed, glabrous, per-

acs ses mae ats black at tip; thorax but slightly margined, one-toothed on the mid-

unequal, punctured ; feet and venter subglabrous. Length nearly seven-tenths of an 
inch. Female glabrous; antenne simple. Length, four-fifths of an inch. This spe- 
cies exhibits the general form of brevicornis, but the thorax is proportionally much
