(Southeastern U. S.) specimens are certainly distinct from those 

 coming from South America. These insects will be more carefully 

 examined later and the results published in a special paper now in 

 course of preparation. 



61. Inusia chimpani, new species. 



Very similar to /. gracillima G.-Tos, but differing from it in its somewhat larger 

 size and darker color. 



Head, except on the sides back of the eyes, strongly punctate. Eyes prominent, 

 separated above by a very narrow space which is sulcate ; the fastigium somewhat 

 ascending, elongate, triangular, shorter than the eyes, rugosely punctate or verrucose, 

 carinate anteriorly. Face viewed in profile broadly concave, the median costa sulcate 

 and coarsely punctate; lateral carina- sharp. Antennae distinctly but not broadly 

 ensiform, nearly as long as the hind femora. Pronotum somewhat dilated on the 

 posterior lobe, punctate, more strongly so on the hind lobe. Lower lateral edges in 

 the female straight, in the male a very little sinuate. Tegmina considerably sur- 

 passing both the abdomen and hind femora, the extreme apex subacuminate. Hind 

 femora just reaching ( 9 ) or considerably surpassing ( $ ) the apex of the abdomen, 

 their genicular lobes somewhat acuminate. Hind tibiae only gently dilated apically, 

 provided externally with seven and internally with nine spines Last ventral segment 

 of male abdomen short and rather blunt, the apex entire. Valves of ovipositor short 

 and slender. 



General color above dark fusco-ferruginous, below greenish testaceous, separated 

 on the sides by a narrow, deep black band which reaches from the hind edge of the 

 eyes to just above the base of the hind femora. The latter greenish, their apices 

 with a ferruginous tinge and marked on their inner genre with black ; hind tibia? pale 

 glaucous, infuscated basally. Dorsum of abdomen fuscous. Antenna- dark ferrug- 

 inous. Wings infuscated. 



Length of body, rj\ 20, ?, 25 ; of pronotum, f, 3.9, ?, 4.5 ; 

 of tegmina, -. , 20, ?, 24; of hind femora, ~, 11.5, -, 14 mm. 



Habitat. — Island of Trinidad, six males and one female, H. D. 

 Chipman, collector, 1 1 1 , VV. E. Broadway (Coll. L. Bruner). 



This insect occurs in British Guiana as well. Still another species 

 of the genus is found in portions of Mexico and Central America. 



62. Stenopola limbatipennis Stal ? 



Three males and one female from the interior of the island are 

 referred here with some doubt. They were collected by H. D. 

 Chipman. 



63. Cornops bivittatum Scudder ? 



Another species of these aquatic or subaquatic Arcridians, which 

 was taken by Mr. Chipman is represented by three specimens 1 ~ 

 and 2 9 ?. It is doubtfully referred to Scudder's Comops bivittatum 

 until it can be studied more carefully.
