MORGAN HEBARD 381 



Coloration. — Type. Head pinkish buff, with a very broad shining post- 

 ocular band on each side, occiput bister paling to tawny-olive laterad andmeso- 

 cephalad, Antennae clay color, becoming sayal brown distad. Pronotum 

 with disk bister, paling narrowly to tawny-olive on each side of prozona; 

 lateral lobes shining dark chestnut brown, narrowly margined ventro-ceph- 

 alad and more broadly ventrad with cinnamon-buff, the dark marking paling 

 slightly to warm sepia on caudal portion of metazonal section. Tegmina 

 bister. Abdomen dorsad cinnamon-buff, with a broad and sharply defined 

 band on each side of shining blackish chestnut brown, which narrows caudad, 

 terminating at the cereal bases. Distal portion of cerci and lateral portions 

 of subgenital plate of this color, running more narrowly around the free 

 margin of the latter. Underparts warm buff. Cephalic and median limbs 

 clay color. Caudal femora externally snuff brown, deepening to bister dis- 

 tad, the dorsal surface with two darker subobsolete transverse bands,, ven- 

 tral surface ochraceous-buff proximad, in remaining portions ochraceous- 

 salmon, with a pregenicular annulus of warm buff. Caudal tibiae dark 

 bluish glaucous, fading proximad to whitish with a weakly defined brown 

 annulus; spines black. 



The allotype is similarly but less contrastingly colored, except that the 

 lateral lobes of the pronotum are differently marked, showing dorsad a band 

 of shining bister which broadens caudad to the principal sulcus, there being 

 about two-fifths as deep as the lateral lobe, the metazonal portion entirely 

 verona brown. In the paratypic series little color variation is shown, some 

 specimens being slightly more reddish than others and the intensity of the 

 markings differing individually to a slight degree. 



The Siskiyou series is much darker. In these the males have no pale 

 margin of the lateral lobes of the pronotum, while the occiput, disk of prono- 

 tum and tegmina are solidly bister, the ventral surface of the caudal femora 

 hay's russet and other portions correspondingly darkened. In the females 

 of this series some have the occiput, disk and lateral lobes of pronotum and 

 tegmina Vandyke brown, with color pattern generally obscured. One speci- 

 men shows, however, a strongly recessive type, being generally ochraceous- 

 tawny, the pronotum entirely of this color, with only a trace of postocular 

 darkening on the head. In this specimen the caudal tibiae are glass green, 

 becoming buffy proximad. 



Specimens Examined: 29; 16 males and 13 females. 



Oregon: Glendale, Douglas County, 1500 to 1900 feet, VIII, 12, 1909, 

 (Rehn and Hebard), 9 d 71 , 7 9, type, allotype and par aty pes. Siskiyou, 

 Jackson County, 4100 to 5800 feet, VIII, 13, 1909, (Rehn and Hebard), 

 7 c?,6 9. 



At Glendale the species was found to be scarce and very active 

 in small openings among the heavy growth of tall firs, in a valley 

 of the Rogue River Mountains. At Siskiyou, on the steep 

 forested slopes of the Siskiyou Mountains, it was found scarce in 



TRANS. AM. ENT. SOC, XLVI.
