Fifth report of the United States Entomological Commission, being a revised and enlarged edition of Bulletin no7, on insects injurious to forest and shade trees . Fig. bajulus.—After Leng. 31. The porter hylotrupes. Hylotrupes bajulus LinniBus. Order Coleoptera ; family Cerambycid^. A beetle very similar to the preceding in its shape and habits, ap-pearing in July and August, .45 to .75 long, of a black color, itsthorax nearly circular and clothed with white hairs, with a smoothpolished black line in its center, and a callous-like spot on each sideof it, and its wing-covers with very coarse, shallow confluent punct-ures and some downy whitish spots, forming two irregular bands nearthe middle. This species is supposed to have been introduced in itslarva state in timber from Europe, and is found in ourcountry only near the sea coast. (Harris Treatise, p. 88.). Fig. 238.—The lesser size. —After Riley. 32. The lesser prionus. Orthosoma hrunneum De Geer. Order Coleoptera ; family A flattened long-horned beetle, to long, andless than a third as broad, •« ith its opposite sides paral-lel, its thorax twice as broad as long, and with threesharp teeth on each side, its wing-covers withtwo or threeslight elevated lines, its antennae scarcely as long as thebody, and its color chestnut red, darker anteriorly Two dozen or more of the grubs were taken,May 26, by Mr. Calder and myself from a verysoft, rotten pine stump; up to June 24 theyhad not pupated in confinement, but by the 5thto the 8th of July one of them became a pupa. Mr. Calder has also found the fully grownlarvse in August in maple logs at Warwick, R. I., and in the rottenwood of another deciduous tree. So that it appears that this beetlelives indifferently in the soft, decayed logs or stumps both of hard andconiferous trees. Larva.—Described w
