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 ) of a little bee with the observation " They 

 were taken on or hovering over Monarda pnnctata." 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 Philoxanlhus 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 flagelluni, spot 

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

 posterior legs and posterior margin of femora of last pair of legs black or 

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

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



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

 sparse indistinct punctures. I<\n'ea on front extending fi oi/i a little 

 below tlie supraorbital line, nearly to the level of the insertion of antennce, 

 close to the eye margins and s/ia//ow. Face distinctly quadrate. Clypeus 

 truncate. Labrum nearly finite as wide as high, V on anterior margin. 

 Clypeus semicircular at base. Space behceeu anterior and lateral ocelli 

 about one-half tlie distance between posterior ocelli; distance between 

 posterior ocf Hi a little greater than that between them and nearest e\ e 

 margin. Xo malar space. Cheeks narrow and rounded. Scape cylin- 

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

 pedicellitm broader thati and longer or about coital to the first joint of 

 the flagellnm ; joints of flagellum subeqiial JMa.villary palpi .v/.r/V -/;//<</, 

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

 length of the other joints fused. Kach side of face with a shallow 

 pit near the insertion of antenna-. 



Thorax. Dorsulum dullish, finely granular, with sparse indistinct 

 punctures and a median impressed line extending from the anterior 

 margin to near tlie middle. Tcgnltz more shining than dorsulum, rest 

 of -the thorax ( except metathorax posteriorly which is more shining) 

 sculptured nearly like dorsulum. /"osta ior fact- of metathorax. with
