4. Isc'hnoptera 'Cxicolor, (Scudder.) 



Platamodes unicolor, Scudder, Bost. Jour. Nat. Hist., VII., 1862, 417. 



Fernald, Orth. New Eng., 1888, 53. 

 Isclmoptera unicolor, Scudder, Proc. Bost. Soc. Nat. Hist., XIX., 1877, 92. 

 McNeill, Psyche, VI., 1891, 78. 



A much smaller species than the preceding but, like it, having both 

 wings and wing covers exceeding the abdomen. General color a pale 

 shining reddish brown. Head and posterior margin of pronotum darker 

 as is also the apical third of the abdomen beneath. Antenme slender, 

 tapering, reaching backwards to the end of the wing covers. Length of 

 body, 12 mm. ; to tip of tegmina 19 mm.; of tegmina 16 mm. ; of prono- 

 tum, 3 mm. 



A single male of this species was taken from beneath an electric light 

 in Terre Haute, Indiana, on the evening of June 12, 1892. On May 28, 

 1893, a number of others were secured in low ground from beneath the 

 bark of a red oak stump. They had evidently just reached maturity and 

 were in company with the imagoes and young of I. pennsylranica. On 

 being exposed to view a number of them flew about 50 feet to a clump of 

 May apple stems, down which they ran and endeavored to hide beneath 

 some dead leaves. Nothing farther of its habits is known by the writer 

 but they are presumably the same as those of I. pennsyJvanica. It has 

 been noted at no other point in Indiana and heretofore has been recorded 

 only from the New England States, Illinois, and Iowa. 

 III. Temxopteryx, Brunner (1865). 



The males of this genus have the sub-anal stylets present, but minute ; 

 the last abdominal sternite of the female is broadly rounded and entire ; 

 supra-anal plate of both sexes with the apex rounded, entire, equal in 

 length to the sub-genital. Pronotum with its lateral edges roundly de- 

 flexed as in Periplaneta, rather than flaring outwards as in Ischnoptera ; 

 much broader in the female than in the male. Body of male rather slen- 

 der; that of female stouter with the abdomen broader than the thorax. 



5. Temxopteryx deropeltiformis, Brunner. 



Temnopteryx deropeltiformis, Brunner, Nouv. Syst. des Blattaires, 1865, 87. 

 Tegmina of females rudimentary covering only about one-third of 

 abdomen ; those of the males fully developed, surpassing the abdomen by 

 5 mm. Color a uniform dark mahogany brown except the tibia? and tarsi 

 of all the legs which are a light reddish brown, the contrast between the 

 two colors in living specimens being very striking.
