OF WASHINGTON. 437 



front, nearly vertical; longitudinal furrow marked by a fine fuscous line; 

 above with a large fuscous spot on each side near occiput. 



Pronotum as broad as long, somewhat narrowed in front; anterior an 

 gles rounded, front margin nearly straight; an interrupted, obscure, pale 

 fuscous line running lengthwise in the middle, and a large, irregular, darker 

 spot each side at the transverse furrow; sides beneath bordered with fus 

 cous. Meso- and meta-notum fuscous, varied with luteous, especially on 

 lateral and posterior lobes, the pattern indistinct. Sides and sterna fus 

 cous and luteous in about equal proportions. 



Abdomen pale fuscous below, luteous above; segment 2 and apical half 

 of the following segments fuscous dorsally; the luteous portions of dor- 

 sum have indications of a longitudinal median dark line. Appendages 

 extremely short (hardly apparent to the naked eye), blunt, divaricate, 

 luteous, very similar in shape to those of Brachynemurus fiusillus 

 Currie.* 



Legs with long, sparse, black and white spines on tibiae; coxae, luteous, 

 marked with fuscous; femora tinged with the same color; apices of 

 tibiae, a ring near their base, and tips of tarsal articles, dark; claws about 

 half the length of last tarsal joint, rufo-piceous. 



Wings a little longer than abdomen, hyaline, the posterior margins 

 slightly incurved apically. Pterostigma white, brown interiorly, a few 

 intercostals forked before it. Veins with long, sparse, black and white 

 hairs; longitudinals pale luteous; with frequent fuscous interruptions; 

 transversals yellow, fuscous or bi-colored. Anterior wings with a series 

 of pale brownish cloudings between subcosta and radius ; another series be 

 tween median and submedian veins, a larger spot at their apical terminus 

 and another at juncture of anal vein and posterior cubital fork; posterior 

 wings narrower and a little shorter than anterior, unspotted, except for a 

 dark clouding at end of mediana. Membranule of posterior wings pro 

 vided with a tuberculiform process which is tipped with a brush of hairs 

 or bristles. 



Female. Abdomen one-fourth shorter than in the male ; other meas 

 urements about the same. Tip of abdomen dark, spinous ; the usual 

 short, hairy, cylindrical appendages below. Wings a little more rounded 

 at tips, the posteriors without tuberculiform process from membranule. 



Described from three specimens, one male and two females, 

 collected in Madera Canyon, Santa Rita Mts., Arizona, June 16 

 and 17, 1898, by Mr. E. A. Schwarz. Two more specimens, 

 females, collected by Dr. R E. Kunze, at Phoenix, Arizona, May 

 16 and June 7, 1897, and kindly loaned me by Mr. C. C.Adams, 

 are smaller than the others, with wings more rounded at tips, 

 posterior margins not perceptibly incurved. They expand 32 to 

 33 mm. This species superficially resembles Brachynemurus 

 sackeni in the markings of wings and abdomen.
