June), has the furcation in one wing but not in the other. Perhaps 

 hellus Loew is only a synonym of tetraspilus Loew. The extent 

 of yellow, or even the presence or absence of such, on the scutellum 

 is a variable character. 



Euparyphus quadrimaculatus new species. 



I cannot remark on the relationship of this species on account of 

 the lack of material in this genus. It runs, in Adams's table {Kans. 

 Univ. Quart., ii, 28), to crucigerus Coq., or atriventris Coq., but the 

 abdominal markings are different. 



9 . Eyes bare. Head yellow, with occiput except orbits, ocellar 

 transverse band, an orbital spot and a fine dash above antennae on 

 frons, and antennae, black. Two brown facial stripes covered by 

 the broad silver along orbits. Cheeks and lower post, orbits silvery. 

 Mesonotum black, with yellow as follows: Two median irregular or 

 interrupted stripes, originating from spot above hmneri, but not 

 attaining posterior margin; broad lateral margins including upper 

 half of pleura, but interrupted above base of wings. Scutellum and 

 spines, and halteres also yellow. All pile short and white. Dorsum 

 of abdomen black; lateral margins, a large lateral spot confluent 

 with margin on third segment, and smaller, similar spots on apical 

 margin of fourth, entire fifth, and venter, yellow. Legs yellow, with 

 fore tarsi, hind tibiae above, four apical joints of middle and hind 

 tarsi, black; base of middle and of hind tarsi white. Wings hyaline 

 with veins and stigma yellow. Mostly micro-granulose. Frons wnth 

 parallel orbits. Face not prominent at antennae. Antenn* not 

 longer than head, with first and second joints subequal. Scutellum 

 short, two or three times as broad as long. Third vein short, not 

 furcate; costal distance between stigma and third not longer than 

 stigma, and hardly longer than discal cell ; four posterior veins faintly 

 distinct, the last arising near base of discal cell. Length, 4 mm. 



Type. — 9 ; Alamogordo, New Mexico, June 6, 1902, (Viereck & 

 Rehn), [A. N. S. P. No. 6202]. 



A male from Santa Clara County, California, June, (W. M. Giffard, 

 No. 7), [Cal. Ac. Sci.], is similar but the upper pleural band is nar- 

 rower. 



AOCHLETUS O. S. 



The discover}^ of two species evidently belonging to this genus, 

 but having the eyes pilose, necessitates including other characters, or 

 establishing the genus upon other than those used heretofore, es- 

 pecially in Williston's "Manual." Osten Sacken ("Biologia," i, 38)
