process which is tipped with a broad brush of short, rufous hairs or 

 bristles. 



Length 18, alar expanse 33.5, greatest width of anterior wing 4.3, 

 antenna 3.4 mm. 



Phoenix, "desert," May n, 1898 (Ktinze : i cJ). 



Type. No. 6885, U. S. National Museum. 



A beautiful little species, suggesting B. coquillelti\v\ the shape 

 of the wings. It appears to be the smallest known member of 

 the genus, although B. pusillus is very nearly as diminutive. 



Brachynemurus schwarzi, n. sp. 



(^. Extremely slender, fuscous, clothed with black hairs. Face luteous, 

 piceous above ; inter-antennal mark rather short, emarginate, bordering 

 the antennae in front and sending a median line towards the clvpeus. 

 Labrum luteous, four times as broad as long, not emarginate. Maxillary 

 palpi luteous, tinged with piceous, the articulations pale. Labial palpi 

 somewhat longer than the maxillary, rufo-piceous, with pale articulations ; 

 third joint rather stout fusiform. Under parts of head luteous, the base 

 of mentum, and elbows and tips of maxillary palpigers, piceous. An 

 tennae ciavate, a little shorter than head and thorax, fuscous, with luteous 

 articulations, the club partly pale; joints i and 2 clouded with piceous; 

 i set in a luteous ring and mostly that color behind. Vertex luteous, a 

 broad, irregular, interrupted band behind and a narrower one in front 

 sometimes interrupted, fuscous.* 



Prothorax luteous, a longitudinal mid-dorsal stripe, divided lengthwise 

 by a pale median line, and two stripes each side, fuscous; beneath Inteous, 

 two fuscous, spots at sides near base. Mesothorax fuscous, luteous as fol 

 lows : a spot on each side of anterior lobe in front and some indistinct 

 ones behind, some spots near base of wings, a divided spot on the inner 

 side of each lateral lobe, hind border and longitudinal middorsal line on 

 posterior lobe, and outer margins of posterior angles; sides and sterna 

 varied with luteous. Metathorax with very similar markings. 



Segments of abdomen luteous in the middle and at their articulations; 

 appendages like those of B. stickeui, but shorter, 2 mm. in length, not as 

 long, although more than half as long, as last abdominal segment. Legs 

 with large black and white spines, luteous, piceous as follows : middle and 

 base of coxae; anterior and middle femora externally and tips of hind fem 

 ora; three rings, interrupted on inner side, on the tibiae one at base, 

 one before the middle and one before the apex; apices of first and fifth, 

 and all of third and fourth, tarsal joints. Tibial spurs as long as joints 1-3 

 of tarsi; claws a little shorter than joint 5. Wings much shorter than 

 abdomen, hyaline with a slight smoky tinge; forewings heavily clouded 

 with fuscous upon most of the transverse veins ; hind wings faintly 

 clouded ; pterostigma whitish, fuscous within, a few intercostals forked 

 before it; veins luteous, interrupted with fuscous principally at their 



*There are usually two luteous spots in the posterior band near the 

 middle.
