11). Last joint of maxillary palpus broadly triangular; thorax less par- 

 allel, the side margins narrowly but evidently reflexed; form more 

 robust. HABRISII. 



mi. Form more oval ; eyes small, not very convex, scarcely larger in the 

 male ; width of front five or six times that of eye as seen from front ; 

 color piceous or dark brown. 



c. Antennae acutely serrate; first two ventrals of male without line of 



erect hairs; sides of thorax flattened. 1661. FUCATUS. 



cc. Antennae subpectinate in the male ; first two ventral segments of male 



with a median line of short, dense, erect hairs; sides of thorax not 



flattened. 1662. LUGUBRIS. 



1660 (5292). XYLETINUS PELTATUS Harris, Trans. Hartf. Nat. Hist. Soc., I, 



1836, 75. 



Elongate-oblong. Brown or reddish-brown, clothed with fine, silky yel- 

 lowish pubescence. Antennae moderately serrate, joints 3 to 10 triangular, 

 terminal joint elongate-oval or nearly spindle-shaped. Head finely and 

 densely punctate, feebly obtusely carinate at middle. Thorax moderately 

 narrowed in front, disk convex, broadly impressed each side on basal third, 

 leaving the median line very convex, resembling a carina ; surface finely and 

 sparsely punctate. Elytra with narrow, lightly impressed stria?, which are 

 finely, not closely punctate. Length 3.5-5 mm. 



Putnam and Kosciusko counties; rare. July 4-September 7. 

 Beaten from the foliage of the Virginia Creeper. 



X. harrisii Fall, length 3.7-5.5 mm., was described from Ohio, 

 Kentucky and Michigan. 



1661 (5295). XYLETINTJS FUCATUS Lee., Proc. Phil. Acad. Nat. Sci., 1865,238. 

 Elongate-oval, convex. Black or piceous black, clothed with fine, short 



and rather sparse pubescence. Antennae with joints 3 to 9 almost twice as 

 wide as long, male, or slightly wider than long, female. Eyes small, sep- 

 arated on the front by about five times their longest diameter. Thorax 

 strongly transverse, median line feebly elevated at base, sides flattened but 

 scarcely reflexed, surface densely, finely punctured and with larger shallow 

 punctures on the sides. Elytra finely rugose-wrinkled, deeply and finely 

 striate, the strke very feebly punctate ; intervals nearly flat. Length 3- 

 5 mm. 



Marion County, scarce. May 28-May 2:). Taken from the side 

 of stone abutments, where they were basking in the sunshine. 



1662 (5296). XYLETINUS LUGUBRIS Lee, Proc. Amer. Phil. Soc., XVII. 1S78, 



612. 



Resembles fiicatus, but smaller and more elongate. Antennae subpecti- 

 nate in male, acutely serrate in female, where the intermediate joints are 

 about as wide as those of male fucatus. Sides of thorax less flattened and 

 more strongly sloping downward on basal half. Length 2.5-3 mm. 



Starke, Marion and Posey counties; scarce. March 23-June 

 18. Beaten from foliage of oak. Probably hibernates beneath 

 bark.
