The Hymenoptera

belonging to the superfamiliesVespoidea and Sphecoidea

obtamed by

the Yale Peruvian Expedition were col- lected in the following localities:

Panama

Canal Zone,

Panama;

San^Miguel,Peru;Santa Ana,Peru;OUantaytambo, Peru; Arequipa, Peru; Desert ^of Salavery, Peru; Cuzco, Peru.

The

following five southeasternPeruvianlocalities,Paltaybamba,Tortontoy,Huadquina, Tincochaca, and

Pampaconas

River can only be found in

some

of themost recentatlases,butthe

Pampaconas

Riverisastreamlying betweenthe

Urubamba

and

Apurimac

Rivers.

Ofthislotof

Hymenoptera

referredto, consisting of26species, 14 are described as new, 11 are determined as heretofore described species, and 1 whichbelongstothegenusPepsis has notbeendeter- mined. Nearlyallofthosespecieswhich were determinedashaving beenheretoforedescribed belongtothe familyVespidae, and mostof these have a wide distribution throughout the entire Neotropical region.

The

insects belonging to the family Eumenidae are all related to insects found

m

the high mountains of the Andes, and more especially with the insects belonging to the Chilean fauna.

Insects ofthe superfamilySphecoidea

show

nospecialaffinities with anyregion, in fact this

may

besaid for

many

of

them

although afew of the species have their allies either in insects belonging to the Chileanfaunaorinsectswhichbelongtothe highmountain faunaof Guatemala, etc.

But

few

Hymenoptera

have ever been described from Peru anditis notsurprisingthat

more

thanhalf ofthosesub- mitted should turn out tobe

new

species.

In the case of the two species of Mutillids described it

may

be possiblethattheyhave beendescribed

by some

oftheolderauthors, butnodescriptioncould befoundtoapplywellenoughto

make

their determinationcertain.

The two

Mutillids are referred to thegenus SphsRrophthalma Blake where they run in Andre's synopsis of the
