SUBFAMILY IV. BLATTIX.K. 97 



moults, the skin splitting along the back and the insect emerging 

 white and soft, but soon hardening and assuming its normal color. 



II. EURYCOTIS Stal, 1874, 13 (Gr., "broad" + "form.") 



Large robust species having the iuterocular area wider than 

 that between the antennal sockets ; tegmina not extending beyond 

 the metanotuni, their hind margins truncate; wings absent; front 

 femora armed beneath much as in Blatta, the spines fewer, stouter 

 and less curved ; tarsi stout, the basal joint especially so, the first 

 four joints with pulvilli ; arolia very large, spinulose. 

 30. BUKYCOTIS FLORIDANA (F. Walker), 1868, 135. Large Florida Roach. 



Male Nearly uniform dark mahogany-brown, legs usually, and pro 

 notum sometimes, reddish-brown; nymphs usually with the sides of pro- 

 meso- and metanota broadly margined with yellow (sabalianiis of Scud 

 der). Pronotum suborbicular, feebly convex, finely and unevenly punc- 

 tate, hind angles obtuse, front ones broadly rounded into apex, hind mar 

 gin truncate. Tegmina subquadrate, finely and rather densely punctate, 

 their outer apical angles rounded and slightly prolonged. Outer apical 

 angles of, fourth to seventh dorsal abdominal segments acute, gradually 

 produced, those of the sixth and seventh forming sharp spines. Supra- 

 anal plate twice as wide as long, its hind margin broadly emarginate and 

 hairy. Cerci short, flattened, pointed. Subgenital plate transverse, 

 strongly emarginate at the insertion of the styles, which are elongate, 

 rather stout and tapering to an acute apex. (Fig. 34, F. ) Female Very 

 similar to $ ; cerci shorter. Supra-anal plate longer, more narrow, its 

 apex more deeply emarginate. Subgenital plate as shown in Fig. 34, E. 

 Ootheca 7x14 mm, dark brown, the sutural edges raised and bearing about 

 16 rather sharp serrations.

This, one of the two native species of the subfamily, abounds 

 throughout Florida, including the southern keys, and is one of 

 the most ill-smelling insects on the Continent of America, far out- 

 stinking any member of the order Hemiptera. Outside of Florida 

 it has been recorded only from St. Simon's and Billy's Islands, 

 and St. Mary's, Ga., and Biloxi, Miss., though it doubtless occurs 

 in many localities in southern Georgia and Alabama. In central- 

 western Florida it is abundant in all stages during the winter and 

 spring months, especially between the basal leaves of the large air 

 plant, Tillaiidsia ulficulufa L., beneath the loose bark of logs and 

 stumps, in and beneath decaying palmetto trunks and leaves, un- 

 der piles of weeds and rubbish, in fact, anywhere it can find shel-
