dorsulum, line on scutellum, nietanotum and on middle-segment 

 above, legs except a small spot on trochanters and a short line on 

 femora, a broad band on dorsal segments of abdomen 1-5 that on 

 first segment strongly emarginate anteriorly in the middle, those on 

 second and third enclosing two approximate black spots, those on 

 fourth and fifth with four emargiuations anteriorly, the posterior 

 margin of all these bands is more or less sinuate, sixth segment 

 yellow apically, ventrals 1-3 entirely and 4-6 with a band, bright 

 yellow ; head and thorax with short, pale pubescence ; wings hya- 

 line, not twice the length of the thorax. Eyes slightly converging 

 above; dorsulum with shallow, confluent punctures, those of the 

 middle segment coarser. Length, 18 mm. 



$ . — Colored like the 9 , but has a greater extent of black on 

 trochanters and femora and thorax, only a lateral spot on dorsulum, 

 the scutellum with two spots, the marks of abdomen separated inter- 

 nally on dorsals 1-6, and those on 1—3 broken into four spots the 

 outer of which are the larger. Antennae long, setaceous, much 

 longer than in any of the other species, the apical joints, especially 

 the last somewhat curved; apical joint of fore tarsi not broadly di- 

 lated; pulvilli distinct; intermediate femora smooth beneath; first 

 joint of intermediate tarsi curved, but not spinose within near the 

 base; second ventral segment with two approximate, elongate 

 tubercles near posterior margin; eighth ventral with a discal spine; 

 last dorsal emarginate at apex. Length 17 mm. 



San Bernardino County, California (Coquillett). Both specimens 

 belong to the U. S. National Museum. The species is remarkable 

 for the long antennas of the male. 



12. Monedula scitula n. sp. 



9 . — Entirely yellow except as follows : a transverse black 

 stripe above and beneath the ocelli ; three longitudinal stripes on 

 dorsulum, the inner of which broadest, largest apically (the dorsu- 

 lum may be described as having a U-shaped, yellow spot), a dark 

 stripe on scutellum anteriorly, one on the middle segment anteriorly 

 and in the middle, and a dark spot anteriorly in the middle on the 

 first and second dorsal abdominal segments, the size of which is 

 variable, that on the second segment being most transverse; antennae 

 (except scape) testaceous above; wings hyaline, long, reaching be- 

 yond apex of abdomen; head and thorax with tolerably sparse, pale
