MEASUREMENTS IN MILLIMETERS OF NYMPHS AND ADULTS OF LARGS SPBCIE=i 



KANSAS SALDID. 



* Venter. t Elytra. 



These measurements were made with micrometer, Bausch and Loml) binocular. 6.1 oculars, 55 mm. objec- 

 tives. By placing millimeter ruler under binocular, micrometer measured ten lines to the millimeter. Thus: 10 

 lines micrometer = 1 mm. 



SMALL SPECIES OF KANSAS SALDID. 



Saldula pOlUpes Fabr. (?)* 



From adults reared from nymphs captured June 1, 1920, along 

 with nymphs of a large black species of saldid, I obtained, June 

 23, several clear creamy- white eggs, thrust in the stems and blades 

 of grass growing in the jars in which these saldids were confined. 

 These were not the first eggs laid, however, as I also found several 

 small nymphs, but the eggs had been so cleverly hidden that I had 

 not found them. These eggs hatched July 1 to 3, and became adults 

 sixteen days later. Eggs from this second generation hatched 

 August 13 and August 20, becoming adults also in from sixteen to 

 seventeen days from the time the nymphs emerged from the eggs. 



On the 28th of July I went to Texas to join my husband, who was 

 in the employ of an eastern oil company. I could not think of 



*Mr. Hung.-rforcl says this .American species is not the same as the Europtan species.
