The unique type was found upon overturning a small boulder on 

 the bare desert. 



HOM(EOGAMIA Burmeister. 

 Homoeogamia erratica Rehn. 



At Deming, July 18 to 20 , a series of eleven males of this species was 

 collected at night about electric lights in the town. All the specimens 

 were taken on rough walls or screens upon which a light shone, excepting 

 one specimen which was flying about a light, much in the manner 

 of a Noctuid, but not so erratic. There is in the lot an appreciable 

 amount of variation in size, and in a few specimens the disk of the 

 pronotum is darker than in others. In all of the eleven individuals 

 the interspace between the ocelli is greater than that between the 

 eyes, although in one specimen the difference is very slight. 



This is the first exact record of the species from New Mexico. 



MANTID^E. 

 YERSINIA Saussure. 

 Yersinia solitaria Scudder. 



On rocky slopes and ledges and on scattered boulders at altitudes 

 of from 4,300 to 6,000 feet this species appears at home. Perfectly 

 protected by its coloration which harmonizes with its environment, it 

 is with considerable difficulty that individuals are located. When 

 disturbed they spring very quickly to a new resting-place, often jump- 

 ing as much as six inches, frequently repeating their spring several 

 times until a place of safety is reached. 



A series of twenty-six specimens was taken at the following localities : 

 Dry Canyon, Sacramento Mountains, 4,900-5,500 feet, July 13, two 

 males and two females; Aden, 4,386 feet, July 21, one male; Florida 

 Mountains, 5,100-5,200 feet, July 19, eight males, five females; Silver 

 City, 5,900 feet, July 20, four males, one female and two with the 

 sex not determinable as the apex of the abdomen is missing in both. 

 The majority of the individuals collected are immature, but several 

 from Dry Canyon, a number from the Florida Mountains and one from 

 Silver City are fully adult. Adult males from the Florida Mountains 

 range from 19 to 22 mm. in length of body, while mature females from 

 the same locality show extremes of 18 and 25 mm. In color numerous 

 shades are present — clay color, ochraceous, orange-red, wood brown, 

 seal brown and greenish-yellow, one specimen being parti-color, the 

 head, pro- and mesothorax and limbs pale orange-red, the remainder 

 of the body very pale ochraceous.
