claws strongly bifid or split, one tooth above the other ; body convex, 

 sub-cylindrical; anterior coxae, not prominent; elytra not striate. 

 Head minutely punctured ; front margin roundly notched, and the 

 f^dge slightly turned up. Thorax with large scattered punctures ; the 

 sides distinctly curved outward at the middle. Elytra not grooved or 

 hairy, but a ridge along the sutural or inner margin of each, which 

 gives the appearance of a single groove on each case, two or three in- 

 distinct ridges on each. Scutellum rather broader than long ; punc- 

 tured at the sides. Almost uniform chestnut-brown ; head and thorax 

 generally darkest ; abdomen varies from reddish-brown to black ; 

 breast covered with yellow, silken hairs. Length from seven-tenths 

 to nearly one inch ; width about one-half the length. The color when 

 the insect first appears is rather lighter than given above, but deepens 

 with age, becoming in some places almost black. 



TIPUIA INORNATA — Say. 



Spec. char. Imago. — General color jet black, unspotted sometimes 

 with a faint bluish tinge ; wings yellowish, fuliginous or smoky. 

 Head punctured ; antenna) pice us, paler toward the top ; mandibles 

 piceus, blackish, at the top. Thorax punctured, wing-scale, and pos- 

 terior margin of the first segment impunctured; the metathorax with 

 three longitudinal, slightly elevated lines. Feet hairy ; abdomen 

 hairy, especially behind. Size varies from two-fifths to three-fifths of 

 an inch. 



Jjarva— Length 0.25-0.50 inch when full grown; greatest diam- 

 eter one-third the length; largest in middle; twelve joints and a 

 sub-joint, exclusive of head. Head bent over on the breast. Color 

 transluscent-white, with a broad transverse, opaque wrinkle around 

 each joint ; on all the stigmata-bearing joints, except one, this wrinkle 

 is constricted into two ellipsoidal pieces dorsally, strongly bulging 

 laterally into semi-oval tubercles, like pendopods, and sub-obsolete 

 ventrally. Labrum edged with brown. Stigmata small, circular 

 brown, and placed on posterior part of joint 1, and on anterior parts of 

 joints 4-11. Anal slit transverse (Riley). 



P. pilosicollis — Knoch. (The hairy May-beetle.) 



This species is rather smaller than the preceding, being only about 

 half an inch long. It differs from that species in the following re- 

 spects : It is generally paler; the head and thorax are reddish-brown 

 and covered with long, pale, yellowish hairs; the wing-cases are pale, 

 reddish-yellow, and covered with hair, and the body is more com- 

 pletely cylindrical. 



With these exceptions, and some slight anatomical differncees, it 

 agrees in its characters with the preceding species. 



It makes its appearance in the Central and Southern portions of 

 this State early in May as a general rule. It appears to be much 

 more abundant in the Southern sections than the former species, in 

 fact I have observed it here, in certain seasons in large numbers, 

 whereas the other species appear to be somewhat rare, unless we may 

 possibly have in this section a variety of that species smaller than the 

 usual size, but which I refer to P. fraterna.
