286 The entomologist. 



Fossores-Crabronid.e. — Crahro leucostomus, Liime. Seven males 

 only from forty pupaa in May. — C. cepJialotcs, Panzer. Ten males and 

 four females, May and June. — C. chrysostoinns, Lep, Sixty-four males 

 and twelve females, May and June. — C. vcu/us, Linne. Thirteen, 

 chiefly males, June. 



ANTHOPmLA-ApiD.E. — AntJwpkom furcotft , Panzer. One female out 

 in May from burrows of Crab)-o vai/ns. 



Lepidoptera. 

 TiNE^. — A Micro moth emerged end of May from pupa found on 

 the cherry-bark, and not yet identified. 



Hemiptera. 



Homoptera-Aphidid^. — Siphonoplwra[rosc£^), S. [pisil). Numerous 

 in "larders" of Pemphredon. 



Diptera. 



Mycetophiltd^. — Sciara mtidicoUia, Meigen ; S. nervosa, Meigen ; 

 S. {pulicari(x, Meigen?): H. {pnecox, Meigen?). Imagines began to 

 appear on April 27th, and continued coming out of the burrows up to 

 June, when about forty had emerged. Twolarvse of S. pracox I found, 

 on April 15th, in an untouched " larder" of Crahro, feeding on a mouldy 

 lihinijia rustrata ; these turned to curious horned pup^e end of April, 

 and one imago emerged end of May. Probably all these iSciara feed 

 in the larval state on the Diptera in the " larders " of Crabro. — 

 Exechia (sp. ?). One specimen in June from borings. 



Chironomid^e. — Ccratopugun (sp. ?). Several, both sexes; pupte 

 seen April 2nd, imagines June 9th, &c. 



PsYCHODiD^. — Trichomyia [urbica, Haliday ?). Two specimens end 

 of May. 



Tachinid.?*:. — Brachycoma crratlca, Meigen. New British species ; 

 bred male and female in May from borings of Peniphredun. Described 

 by Dr. Meade in Ent. Mo. Mag., May, 1694, p. 110. 



Anthomyid.e. — Hijetodcsia errans, Fallen. One female, May 13th, 

 from fossorial borings. — Hyleinyia /estiva, Zetterstedt. Rare ; bred 

 both sexes. Sixteen from borings of Pewpliredon ; out from April 26th 

 to May 18th. Described by Dr. Meade in Ent. Mo. Mag., October, 

 1898, p. 285. The above specimens are recorded in same Mag. of 

 December, 1893. 



Sapromyzid^. — Lonchaia var/inalis, Fallen. Three females, April 

 and May, from borings of Pemphredon. 



The following Diptera I identified among the stored prey in par- 

 tially consumed and in untouched "larders" of the four species of 

 Crabro. Numerous stores still remain to be examined. 



Stratiomyid.'e. — Microchrysa polita, Linne. Both sexes in nidus of 

 Crahro leucostomus. 



Syrphid.e. — Melanostoma [mellinum f). In nidus of Crahro leuco^ 

 stomiis. — Fyroplicena ocymif F. Females in nidus of Crahro (sp. ?). — 

 iiatychirus ulbimaniis, F. In nidus of i'rabro (sp. ?). — P. falviventris, 

 Mcq. Eight in one "larder" of Crahro chrysostovius. — P. dypeatus, 

 Mg. Several in nidus of Crabro (sp. ?). — Syrphus balteatus, Deg. (one 

 female); S . ribesii, himnQ (two females). In one "larder" of Crabro
