OF WASHINGTON. 279 



lary and labial palpi not black but luteous, tinged with rufous, 

 the superior dark line on middle and posterior femora merely 

 indicated by a number of more 01' less confluent dots.* The wings, 

 too, are less heavily marked. These differences do not seem to 

 justify making this a new species, although additional material 

 may show it to be a good geographical race. 



Brachynemurus tuberculatus Banks. 



Madera Canyon, Santa Rita Mountains, June 8 and 14 

 (Schwarz : i J, 2 9 9) ; Hot Springs, July i (Oslar : i <^). 

 Brachynemurus delicatulus, n. sp. 



J\ Slender, yellowish, with rather sparse white hairs. Face piceous 

 above, except a yellowish spot just behind the antennae; inter-antennal 

 mark short, narrowly bordering the antennae in front and sending a median 

 line towards the clypeus. Mouth parts luteous; labrum three times as 

 broad as long, not emarginate ; labial palpi somewhat longer than max 

 illary, third joint very stout fusiform, rufo-piceous around ocelloid spot, 

 the tip fine and cylindrical. Maxillary palpigers rufo-piceous at their 

 elbows. Antennae strongly clavate, a little shorter than head and thorax, 

 fuscous, with pale articulations; joint i principally luteous; 2 piceous 

 except at base, conspicuously wider than third and following joints. Ver 

 tex rufo-fuscous, a pair of yellowish spots at middle of posterior border 

 and other indistinct spots on sides and in front. 



Prothorax marked with a pair of longitudinal fuscous stripes which are 

 broad and approximate behind, narrowed and widely separated in front 

 and ending in the transverse furrow; lateral margins behind the furrow 

 and a stripe each side below fuscous. Mesothorax fuscous, marked dor- 

 sally with yellowish as follows: a spot in front of each wing; two sub- 

 triangular, almost connected, spots near middorsal line on lateral lobes 

 and a small one at base of wing; posterior angles; rear portion of pos 

 terior lobe except an indistinct longitudinal dark line in the middle. 

 Metathorax fuscous, varied with yellowish very much as in the mesothorax. 

 Sides and sterna with small yellowish markings. 



Abdomen fuscous, a line each side and an apical ring on the segments 

 yellowish ; appendages extremely short, obtuse, yellowish, clothed with 

 long white hairs. Legs unspotted, beset with black and white spines, the 

 anterior and middle coxae fuscous at base ; tibial spurs as long as first four 

 tarsal joints ; tarsal joints piceous apically, 2, 3 and 4 almost entirely that 

 color; claws as long as joint 5 of tarsi. Wings a little longer than the abdo 

 men, hyaline, unspotted, slightly falcate at tips shaped as in B. coquilletti ; 

 pterostigma luteous, fuscous within, a very few intercostals forked before 

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

 submediana pale; membranule of hind wings with a pale tuberculiform 



* Although the fact is not indicated in the original description, this dark 

 line occurs only on the middle and hind femora, the anterior femora being 

 wholly pale.
