NO. 1 124. EE VISION OF THE MELA NOPL ISC TD DER. 395 



posterior parts of the genae above the lower level of the eyes dark 

 reddish brown, with a mediodorsal thread of testaceous, and another 

 behind the middle of the upper half of the eyes; whole face and espe- 

 cially frontal costa punctate ; antennae ferruginous, apically infuscated 

 Prouotuin with the metazona ferrugiueo-testaceous, the prozona very 

 dark reddish brown, the upper two-thirds of the lateral lobes piceous 

 or plumbeo-piceous, sometimes merely dull piceous, with black sulci, 

 the lower portion of the lobes including the metazona luteous, fadiug 

 upward gradually on the metazona. Mesonotum, metanotum, and 

 abdomen dark reddish brown, with a sometimes obsolete, slender, flavo- 

 testaceous or ferrugineo-testaceous dorsal stripe edged with black, 

 which in some cases reappears on the prozona of the pronotum. Teg- 

 miua about as long as the prozona, 1 subequal, three or four times as 

 long as broad and well rounded at tip, fusco-testaceous, lighter along 

 the inner (upper) margin. Legs luteous, more or less heavily tinged 

 with ferruginous along the upper surface, the hind femora more than 

 the anterior pairs, the carinae being often more or less heavily marked 

 with black, the genicular arc black; hind tibiae very feebly incurved, 

 yellow luteous, the spines black-tipped. Supraanal plate of male trian- 

 gular with slightly rounded sides, the tip well rounded, with a deep 

 basal median sulcus, half as long as the plate and bounded by rather 

 high ridges, which after uniting in the middle again part slightly and 

 run parallel to the apex, leaving a slight sulcus between them; furcula 

 consisting of a pair of slightly separated minute triangular lobes; cerci 

 slender, slightly compressed, tapering gently on basal half, beyond 

 very slender, subcylindrical, scarcely tapering, acuminate, and curved 

 downward (the latter feature not shown in the figure); infracercal 

 plates rather short, rounded, concealed by the recumbent cerci. 



Length of body, male, 17 mm., female 19.5 mm.; antennae, male, 6.75 

 mm., female, 6 mm.; tegmina, male and female, 3 mm.; hind femora, 

 male, 8.75 mm., female, 10 mm. 



Seven males, 7 females. Montana, L. Bruner (L. Bruner; S. H. 

 Scudder; U.S.N.M. Kiley collection); Loon Lake, Oolville Valley, 

 northeastern Washington, July 23-25, S. Henshaw( Museum Compara- 

 tive Zoology). 



Bruner states that the Montana specimens were taken near Helena 

 " among the trailing junipers on north mountain slopes, at moderate 

 elevations." He also states that the colors of the living insect are 

 much more vivid than in cabinet specimens. " The yellowish hair- 

 lines and dorsal line of the abdomen are glossy white, while the front 

 and lower surface are of a bright lemon yellow; the brown is a bright 

 hazel." 



In some specimens, especially of the female, the pronotum is crossed 

 by a narrow testaceous stripe which cuts the darker markings, running 



Bruner states that the tegmina are sometimes absent, but I think only from indi- 

 Tiduals that have lost them by accident. I have seen only one in which they were 

 lost from both sides; several iu which they have been lost from one side.
