not anywhere of sufficient abundance to be of great value in 

 checking the increase of noxious insects." 



130a (216a). Perillus bioculatus clanda (Say), 1825, 312; II, 240. 



Differs from typical bioculatus only in color, the black of that form 

 being replaced by brown or piceous, and the red or orange by ivory- 

 white or yellow. Elytra ivory-white with the narrow inner margin and 

 a median triangular spot black. 



Marion Co., Ind., July 21 ; one swept from herbage on margin 

 of pond. This is the form which has been most frequently 

 recorded from the eastern states, though but few of the later 

 records differentiate the two. Davis has taken it on Staten 

 Island in June. 



131 (217). Perillus circumcinctus Stal, 1862, 89. 



Elongate-oval, convex. Above pale chocolate-brown; pronotum with 

 front and side margins, a narrow median line and sometimes a narrow 

 cross bar between the humeri, ivory-white or pale yellow, the front 

 portion with an oblong black or fuscous spot each side of middle; scutel- 

 lum entirely surrounded by a broad ivory-white marginal stripe, this 

 narrow at base and along basal half bordered each side with very coarse 

 brown punctures ; connexivum black, its narrow edge and the entire 

 costal border of elytra, ivory-white; abdomen chocolate-brown, the sides, 

 a spot at middle of second and third ventrals and the ventral spine yel- 

 low; thoracic pleura paler brown with yellow markings; legs pale red- 

 dish-brown, the tibiae with a submedian yellow ring. Head much more 

 sparsely punctate than in bioculatus, otherwise as there. Pronotum 

 slightly longer and more narrow, with front portion less declivent, the 

 punctures much coarser, sparsely and unevenly placed, the tooth of 

 front angles very short and blunt; hind portion more evenly, but coarsely 

 and very sparsely punctate. Scutellum with basal half coarsely unevenly 

 punctate, the apical portion more finely and evenly so. Elytra finely, 

 shallowly and quite evenly punctate. Abdomen with sides finely, sparsely 

 but distinctly punctate, its middle smooth; thoracic pleura with very 

 coarse sparse punctures. Hind margin of genital plate of male semi- 

 circular, subtruncate, with a small median notch. Length, 9 — 11 mm.; 

 width, 5 — 6 mm. 



Rock City, N. Y., June 6 (Denis). Chicago and Forest City, 

 111., April 28 — June 6 (Hart) . Not yet taken in Indiana, though 

 doubtless occurs in the northern portion of the State. Ranges 

 from Ontario and New England to Manitoba, Nebraska and 

 Dakota. Not recorded south of New Jersey, central Illinois and 

 Missouri, though Uhler (1872, 395) says it occurs in "Panama 

 and the Island of Trinidad." About Buffalo, N. Y., Van Duzee 

 (1894, 170) found it on coarse weeds, bushes and trees in July
