provisioned. Where several nests are in close proximity their 

 respective cells cannot always be associated. One nest which 

 I laid hare liad three cells, an older one showed twelve, while 

 a completed one had eighteen, each containing a Avasp cocoon. 

 The twelve-cell nest had .'>-l(5 h()])])er8 to a cell, hut in some 

 instances the cells were not yet completely provisioned, while 

 others contaiiuMl hiriiv larvae ov cocoons with a few perfect 

 hoppers and a (piantity of small fragments of the provisions.- 



]^one of these or other interned hoppers showed any move- 

 ment, in fact some were not in good condition, among them 

 being mouldy specimens. But one egg is laid to a cell. The 

 egg is glued on the underside of one of the hoppers, being 

 secured longitudinally thereto so that its anterior or head end 

 is near or touches the base of one of the fore legs of its host. 

 The egg is very slightly curved, several times longer than its 

 thickness wliicli is nearly uniform througliout, being very little 

 more bluntly rounded at its anterior than at the posterior ex- 

 tremity. It is 2.5 mm. in length and pearly white. 



The larva hatches probably in about two days and devour- 

 ing its store of provisions at the end of about six days more, 

 commences to spin its cocoon. It is then about 12 mm long 

 and spindle shaped, the head is of medium size and provided 

 with sharp and slender jaws. The body is well segmented 

 though the lateral folds are not plainly marked, while the 

 whole skin is provided with very fine transparent gi'anulations. 

 The mid-gut is lead color, while both etxremities of the body 

 are glassy white. The silken cocoon is rather delicate, sur- 

 rounded by bits of soil and leaf hopper remains, it tapers a lit- 

 tle more at the ]iosterior end, measures from 10 to 15.5 mm. 

 long by 3.5 to 5 mm. at its greatest breadth, and is of a light- 

 l)rown or tan color. A large female pupa (Fig. ?>) is about 

 18 mm. long and is rather stout for so slender an insect, the 

 waist being comparatively thick. The top of the head bears 

 two pairs of spines and the mesonotum a pair of low tubercles. 

 There are no lateral tubercles luit the processes on the antennae 

 and legs are knobbed. Its first color is prol)ablv pearly white.
