Hab. Only a single îemale spécimen, the type, is at hand. 

 It was taken in Peru at a point 11° 3' south, 75° 17'west ofGreen- 

 wicli and at an élévation of about 1800 meters above tide water. 

 The coUector was Nicliolas I к о n n i к о v. 



Sitalces nudus В г u n e r. 



A pair of a|)teroiis locusts belonging to the genus Sitalces 

 seem to be identical with S. nudus В r u n e r to be described in a not 

 distant number of the Proceedings of the Carnegie Museum along 

 with several other species of the genus. The type spécimens (c? and 5) 

 are alcoholic and not in color. It is well, therefore, to make a 

 note hère of the colors as they appear in the spécimens now before 

 me. Occiput, cheeks back of the eyes, most of the pronotum and 

 upper portion of the meso- and metathorax, together with the dorsuni 

 of the first to thii'd abdominal segments strongly infuscated. Face, 

 lower margins of the cheeks and lateral lobes of the pronotum and 

 a couple dashes on pleura creamy white with a greenish tinge at 

 places. Median and location of lateral carinae of pronotum and dor- 

 sal carina of the abdomen flavous. Legs olivaceous-green, the geni- 

 cular portion of bind femora largely black. Antennae pallid at base, 

 infuscated apically. Under side pale greenish yellow. 



Hah. These insects were taken November 3, 1906, at the 

 point so often referred to in this paper in connection with other 

 species. 



Schistocerca pallens Thunb. 



One maie and four female spécimens of Schistocerca pallens 

 T h u n b e r g are at haïul from the eastern slopes of the Andes to 

 the eastward of Cerro de Pasco. They are very similar to other spé- 

 cimens examined by me from varions Brazilian localities. 



Dichroplus peruvianus Stal. 



There are several spécimens including both sexes and a 

 couple of nymphs of St<ârs Dichroiüus penivianus тХЫ co\\%(^{\on 

 made at the prevailing locality. These insects were taken during 

 the months of September to Decembei', and were found at élévations 

 ranging from 1000 to 1800 meters above the sea-level. With the 

 exce|)tion of wing-length there is little variation among the spécimens 

 examined.
