THE GROUND OR BURROWER BUGS. 73 



bristly hairs ; hind tibiae as described in key ; tarsi slender, the 

 first joint longer than the other two united. 



Two North American species are known, both neotropical, 

 one extending north into California, the other into the east- 

 ern states. 



34 (44). Cyrtomenus mirabilis (Perty), 1834, 166. 



Broadly oval, convex above and beneath. Dark chestnut-brown, 

 shining; ocelli pale red; antennae, beak and legs brownish-yellow; abdo- 

 men dark reddish brown. Head with front margin semicircular, surface 

 impunctate, but with numerous coarse wrinkles and a row of erect coarse 

 bristles within the refiexed margin, these often eroded. Pronotum with a 

 rather wide median transverse groove and a median depression near 

 front margin, these coarsely, irregularly punctate, remainder of disk with 

 a very few coarse punctaures. Scutellum coarsely and very sparsely 

 punctate, its sides feebly sinuate near tip; frena extending to the sinua- 

 tion. Elytra with coarse punctures along the grooves, elsewhere only 

 vaguely and shallowly punctate. Under surface impunctate, the mar- 

 gins of abdomen ciliate with a few long remote bristles ; osteolar areas 

 minutely granulate. Genital plate of male short, almost concealed by 

 sixth ventral, its hind margin truncate. Length, 6.5 — 9 mm.; width, 

 4.5 — 5.5 mm. 



Dunedin, St. Petersburg and Moore Haven, Fla., Jan. 21 — 

 June 10. Taken at electric lights and about the roots of tufts 

 of grass and beneath cover near the margins of ponds and 

 lakes. Recorded from numerous other Florida stations and 

 probably occurs sparingly throughout that state. It is our 

 largest member of the family and ranges from Staten Island, 

 N. Y., and southern Illinois, south and west to Texas, Califor- 

 nia and Central and South America. Hart (1919, 205) records 

 the taking of a single example, Aug. 1, at a street light in 

 Cairo, 111., and states that "adults and numerous nymphs were 

 sent me from Georgia as injurious to the chufa or edible sedge- 

 root, Cyperas esculent us L." 



II. Pang^us Stal, 1862, 95. 



Broadly oval subdepressed species of large size for the fam- 

 ily, having the head subporrect, as wide or wider across the 

 eyes than long, apex very broadly rounded, margin feebly re- 

 curved but without a groove thickly beset with bristles behind 

 it ; cheeks wide, flat, their margins not sinuate ; ocelli small, 

 widely separated ; antennae short, not reaching hind angles of 

 pronotum, joints 2 and 3 each slightly shorter than 4 or 5 

 which are subequal in length, subfusiform and stouter than 2 ;
