Two New species of the Bee Genus Perdita from 



Indiana and New Jersey. 



By Henry L. Viereck. 



Perdita gerhardi n sp. 



My friend Mr. \Vm. J. Gerhard recently sent me specimens 

 (four 9 and two S ) of a little bee with the observation ' ' They 

 were taken on or hovering over Monarda punctata.'' .Their 

 color is much like the hue of the bracts and corolla of the flower 

 they visit. My finding this little bee undescribed prompted 

 me to determine a species I had taken in New Jersey on the 

 same flower — this likewise proved to be an undescribed species. 



I sent a specimen of P. gerhardi to Prof. Cockerell who 

 kindly sent a table of allied forms. 



P. gerhardi has characters of Philoxanthus Ashmead and 

 Perditella Ckll. Length of female 5.5 mm. 



Color — Bright yellow with brownish tinge ; scape, head, dorsulum, 

 pleura and legs with a ferruginous tinge ; greater part of flagellum, spot 

 mesad of each fovea, fovea?, spot on lower third of mesopleura, tarsi of 

 posterior legs and posterior margin of femora of last pair of legs bla^k or 

 blackish. Margins (posterior) of first three dorsal segments of abdomen 

 blackish. Wings pale yellowish, stigma pale yellow, nervures brownish. 



Head very tinely granulose. Clypeus and sides of face adjoining with 

 sparse indistinct punctures. Fovea on front extenditig from a little 

 below the supraorbital line, nearly to the level of the insertion of antenna, 

 close to the ^e margins and shallozu. Face distinctly quadrate. Clypeus 

 truncate. Labruni nearly tivice as wide as high. V on anterior margin. 

 Clypeus semicircular at base. Space between anterior and lateral ocelli 

 about one-half the distance betzveen posterior ocelli; distance between 

 posterior ocelli a little greater than that between them and nearest eye 

 margin. No malar space. Cheeks narroiv and rounded. Scape cylin- 

 drical as long as or a little longer than first four joints of flagellum ; 

 pedicellutn broader than and longer or about equal to the first joint of 

 the flagellum ; joints of flagellum subequal. Maxillary palpi six jointed, 

 joints subequal, labial palpi four jointed, first joint nearly twice the 

 length 0/ the other joints fused. PZach side of face with a shallow 

 pit near the insertion of antennae. 



77;o/-a:.i-.— Dorsulum dullish, finely granular, with sparse indistinct 

 punctures and a median impressed line extending from the anterior 

 margin to near the middle. Tegulce more shining than dorsulum, rest 

 of the thorax (e.xcept metathorax posteriorly which is more shining) 

 sculptured nearly like dorsulum. Posterior face of metathorax with
