Ischnoptera johnsoni n. sp. 



Type : ^ ; St. Augustine, St. John County, Florida (C. W. 

 Johnson). [A. N. S., Phila.] 



Apparently closest* allied to /. 7iigricollis Walker (Catal. 

 Blatt. Brit. Mus., p. ii8), but differing in the shorter and 

 darker tegmina, the more reflexed lateral borders of the pro- 

 notum and the blackish abdomen. In color this species bears 

 considerable resemblance to /. linearis (Serville) from South 

 America, but that is structurally different, and is also a larger 

 insect. 



Size small ; form elongate and graceful. Head with the interspace 

 between the eyes of moderate width, and about equal to that between 

 the elongate-ovate ocelli ; antennae filiform, slightly pilose, not exceeding 

 the body in length. Pronotum with the disk somewhat flattened, and 

 bearing two shallow postero-lateral, sub-circular depressions ; lateral por- 

 tions of slight depth, but quite sharply deflected; anterior and posterior 

 margins very broadly rotundate, lateral margins straight, the angles 

 broadly rounded. Tegmina rather elongate; basal field narrow, of little 

 extent, sub-coriaceous; marginal field narrow, the costal veins very num- 

 erous, closely placed, and extending quite uniformly to the tip of the field; 

 veins of the discoidal field longitudinal ; anal field sub-hastate in form, 

 the veins closely and evenly disposed. Wings with the costal veins num- 

 erous and closely placed; medio- discoidal space considerably greater than 

 the.medio-ulnar ; anterior ulnar vein with three complete and five incom- 

 plete rami. Abdomen depressed; supra-anal plate narrow, produced, the 

 apex subtruncate, and with a broad, shallow median depression; cerci 

 depressed, attenuate, over twice the length of the supra-anal plate ; sub- 

 genital plate produced, fornicate, apical styles small. Limbs compara- 

 tively slender, the posterior metatarsi over half as long again as the 

 second and third tarsal joints. 



General color blackish vinaceous; limbs sienna; ocelli whitish. Pro- 

 notum and head blackish ; tegmina deep vinaceous, becoming paler 

 toward the extremities ; wings slightly suffused with pale vinaceous, 

 strongest apically; the veins of the same color, but of a more solid tint. 

 Upper surface of the abdomen and abdominal appendages blackish 

 vinaceous.
