provisioned. Where several nests are in close proximity their 

 respective cells cannot always be associated. One nest which 

 I laid l>are had three cells, an older one showed twelve, while 

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

 The twelve-cell nest had -"j-lG hop])ors to a cell, bnt in somo 

 instances the cells were not yet completely provisioned, whiie 

 others contained large larvae or cocoons with a few perfect 

 hoppers and a quantity of small fragments of the provisions.- 



Xone 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 imderside 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 es'2: is very slii>-htlv curved, several times longer than its 

 thickness whieli is nearly imiform throughout, 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 prol)ably in al)Out ttvo 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 lon^ 

 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 gTanulations. 

 Tlie 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 leafhopper remains, it tapers a lit- 

 tle more at the posterior end, measures from 10 to 15..") mm. 

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

 brown or tan color. A large female pupa (Fig. o) is al)out 

 13 liim. 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 l)iit the processes on the antennae 

 and legs are knobbed. Its first color is proliably pearly white.
