SUBFAMILY X. PANESTHIN.E. 



March 15, July 07. Those at Big Pine Key were beaten by R. & 

 H. from tall bushes on the edge of a mangrove swamp, while at 

 Key West they were mainly secured by beating the foliage of a 

 holly, Uea- cossinc L. Recorded by R. & H. (1905, 33; 1912, 241; 

 1914c, 382) as Plectoptera poeyi (Sauss.), a closely related Cuban 

 species. 



Subfamily X. PANESTHIN^. 



Large robust species having the surface leathery; ocelli, teg- 

 niina and wings absent in our species; last dorsal and ventral 

 abdominal segments very large, triangular, completely concealing 

 the supra-anal and subgenital plates and genitalia; legs stout; 

 lower front margin of fore femora armed only with three short, 

 stout, equal spines near apex; other femora either unarmed or 

 with two similar subapical spines; first four tarsal joints with 

 heavy pulvilli; arolia absent (Fig. 43, U). One genus is repre- 

 sented in this country. 



I. CRYPTOCERCUS Scndder, 1802, 419. (Gr., "hidden" + "cerci.") 



Eyes very small, convex, subequal in size to the antennal 

 sockets; pronotum convex, broader than long, disc with a wide, 

 deep median depression, front margin broad and slightly upturned 

 to form a hood above the head. Other characters as given above. 



42. CRYPTOCERCUS PUNCTULATUS Scudder, 1862, 420. Brown Wingless 

 Cockroach. 



Dark chestnut-brown, shining; the apical margins of the dorsal seg- 

 ments paler; antennae and legs reddish-brown. Eyes and vertex concealed 

 by pronotum; face finely and sparsely punctate. Pronotum roughened 

 with small, scattered granular tubercles and with a few larger ones each 

 side of median depression; hind margin truncate, front one broadly 

 rounded. Dorsal segments finely and sparsely punctate, the last two or 

 three with numerous small rounded tubercles, the terminal segment trian- 

 gular with lateral margins raised and apex truncate. Cerci hidden, but 

 stout, rather short, tapering, the joints indistinct. Sixth ventral seg- 

 ment produced to meet the last dorsal one, its apex rounded and sides 

 finely granulate. Female inseparable externally from the male. Length 

 of body, $ and ?, 23.5 29; of pronotum, 7.18 mm. Width of pronotum, 

 99.9 mm. 



This peculiar roach occurs in hilly or mountainous regions 

 from New York and Maryland, southwest to northern Georgia 

 and central Kentucky; also in Oregon, Washington and Califor- 

 nia. 22 It appears from the records to be most abundant in Vir- 



-Scudder, Psyche, IX, 1901, 288.
