 Blattidae. 



1. Blattelhi gevmanicn Linn. Croton-bug. Station I, 7, camp. Lot 

 179. July 28. A single female with ootheca. Probably introduced in 

 merchandise. 



Acridlidae. 



2. Steno'bothrus curtipennis Harr. Stations I, 7, camp; Y, 3; V, 5; 

 I, '04 and YIII, '04. Lots 99 A., 134 A., 137, 228, 232. July 24 to 

 Aug. 24. 



This species is a characteristic inhabitant of moist, grassy or sedgy 

 meadows. It was taken in the cassandra and hummock zone at V, 5, 

 and in a clearing near end of Wendigo road at Washington Harbor. 

 Both long — and short-winged forms were secured. 



3. Chloealtis ahdominalis Thom. Stations II, 3; IV, 5; and I, '04. 

 Lots 121, 143, 154 A. July 21, 25, Aug. 24. A young male in 5th stage 

 on July 21. 



4. Chloealtis conspersa Harr. Stations I, 1 ; II, 3 ; and I, '04. Lots 

 22, 143. 141, 147, .154 A. July 6 to Aug. 24. A young male in 5th stage 

 on July 6. Some of the males of this species show indications of the 

 more closely reticulated spot in the tegmina so characteristic of ab- 

 dominalis. 



The species of this genus are dwellers in thicket and woodland edges, 

 ovipositing usually in decayed, though sometimes in firm, wood. 



5. Mecostethus lincaius Scudd. Stations II, 5; V, 5; Y, 11; and I, 

 '04. Lots 91 A., 136 A., 154 A., ISO. July 8 to Aug. 24. 



• Numeroiis immature examples of this genus are referred to this 

 species with some doubt, and it is quite possible that some of them be- 

 long to an allied species. The hind tibiae of these young specimens are 

 markedly fuscous. 



6. Gamnula pelliicida Scudd. Stations I, 7; IV, 5; Y, 3; and I, '04. 

 Lots 121, 133, 222, 228, 154 A. July 21 to Aug. 24. Young in 4th and 

 5th stages on July 21 and 22. 



The representatives of this species, like those of some others, are un- 

 usually dark in color, a phase of coloration probably correlated with the 

 humid climate or soil background. This is a campestral species, occur- 

 ring plentifully from Atlantic to Pacific oceans in the boreal zone, 

 usually upon dry, upland soil. 



7. Hippiscus tuhcrculotiis Palis. Coral-winged Locust. Stations 

 IV, 5; IV, 9; V, 9. Lots 121, 122, 215. July 21 to Aug. 7. 



This species is represented by 6 males, 4 females, which differ marked- 

 ly from typical eastern examples in being deeply infuscated, the hind 

 tibiae coral red except on basal half of outer side, and in having the 

 posterior process of the pronotum more produced. 



This large locust is an inhabitant of clearings on dry soil. Its bright-
