as the third ; fifth protruding in almost hemispherical form, the first four 

 segments have each a large shining black spot on the dorsum, interrupted by a 

 rather indistinct median gray pruinose line ; on the second and third seg- 

 ments these spots are triangvilar, narrowing forward almost to a point, while 

 behind they are almost as wide as the dorsum; along the side of the second 

 and third segments there is an indistinct brown streak ; remainder of abdomen 

 ashy-gray pollinose, the hairs arising from brown dots. Wings as usual. 

 Length, 6 mm. 



Female. — Head about 2.47 times as wide as front; sides of face con- 

 siderably wider and more hairy, otherwise all the characters of the male 

 are found, even the enlarged facets ; in the place of the two rows of bristles 

 on the lower side of the hind femur there is only a single bristle or sometimes 

 two. Length, 7 mm. 



A common and widespread species, occurring in Europe and 

 throughout the United States. Specimens are in my collection from 

 Buffalo, N. Y. (M. C. Van Duzee) ; Algonquin, 111. (Nason) ; Brook- 

 ings, S. D. ; and a number of places in Idaho, Utah, Nevada, Califor- 

 nia and Washington. It is on record from St. Vincent, W. I.; 

 Mexico; Florida, Ontario, etc. 



Lispa antennata new species. 



A slender species with opaque abdomen, wide sides of face and cheeks, 

 and second antennal joint tipped with reddish-yellow. 



Male. — Head 2.06 times as wide as front, the latter very little narrowed 

 at the antennae, frontal orbits narrow, more distinctly yellow anteriorly ; 

 antennae black, second joint at tip narrowly reddish-yellow, which changes to 

 whitish when viewed from below, third joint short, arista with long plumosity ; 

 face wholly grayish-white pollinose, wide above and rapidly becoming still 

 wider below on account of the triangular form of the facialia, which are 

 nearly as wide at the level of the vibrissse as the sides of the face are ; the 

 hairs of the frontal orbits continue down on the sides of the face or facial 

 orbits to about the level of the vibrissae, but are scattering on the upper part; 

 a single large vibrissa with three or four small bristles in a row laterad 

 across the lower end of the facialium ; palpi light yellow, with a rather sudden 

 enlargement, covered with scattering black hairs except on the outer side in 

 front, where there is a bare, glistening whitish spot. 



Thorax cinereous, with no dark longitudinal lines except at the very front 

 edge ; chaetotaxy normal, bristles well developed ; pleurae concolorous ; halteres 

 yellow ; calypteres ivory-white. 



Abdomen cylindrical, cinereous, second and third segments each with a 

 dull blackish spot on each side, rather faint (on the first segment still fainter),' 

 fourth segment capable of a good deal of retraction and generally exposed for 

 a much shorter length than the preceding ones; fifth segment very narrow and 

 visible only for a small space dorsally ; hypopygium of moderate size, con-
