THE CANADIAN ENTOMOLOGIST. 245 



saw my first Orchard Oriole ; and a few rods further on, the larder of a Northern 

 Shrike; the bird was fluttering at the top of a barb wire fence and on my ap- 

 proach flew heavily away with what looked like a sparrow ; on examining the 

 fence I found the two top strands of wire, all the way along between two posts, 

 had been used for killing and hanging the butcher's meat, the barbs having 

 remains of beetles, birds and mice smeared about them.

ON SOME ARACHNIDS FROM SOUTHERN UTAH 



BY RALPH V. CHAMBERLIN, 

 Cambridge, Mass. 



In a small collection of spiders and scorpions from St. George, Utah,\ 

 sent me for identification, are representatives of two new species which are 

 here described. The other species in the lot are also listed. The material 

 was collected by Mr. V. L. Tanner. 



Araneina. 



Dictyna volucripes Keyserling. 



One female of this widespread species, which is common in central and 

 northern Utah. 



Psilochorus utahensis Chamberlin. 



One female apparently this species, which is common in Millard Co., 

 from where described. 



Physocyclus tanneri, sp. nov. 



Female. — As compared with P. glohosus Tacz. this is a larger species 

 with much longer and stouter legs. It may at once be distinguished by lacking' 

 the caudal process at caudal end of cephalothorax and the opposing chitinous 

 spot on abdomen which are characteristic of glohosus. The abdomen is ob- 

 viously less elevated and more flattened above, and in front protrwdes farther 

 over the cephalothorax; its anterior end somewhat bigibbous (cf. fig. i.) The 

 epigynum has the anterior processes larger as compared with the posterior 

 portion and much more widely separated, posterior portion less protuberant ; 

 the fold just back of genital furrow stronger, on a level with contiguous part 

 of epigynum, dark and chitinous. The epigynum more resembling that of 

 P. cornutus of Lower California. Cf. Plate X, figs. 2, 3, 4 and 5. 



Length 4.5 mm. ; length of. leg, 1.33 mm. 



Two females. 



Philodromus virescens Thorell. 

 Philodromus clarus Keyserling, Die Spinnen Amerika, 1880, I, p. 214. 



One male of this form, which is common farther north on sage-brush. 



Philodromus utus, sp. nov. 

 In alcohol the carapace is greyish fulvous, with a lighter greyish median 

 longitudinal stripe more or less evident. Legs colored similarly to carapace. 

 Abdomen grey, without distinct markings. Venter pale. Posterior median 

 eyes a little more than twice their diameter apart, about half as far from the 

 laterals, or a little more. Anterior lateral eyes nearer to the posterior medians 

 than to the posterior laterals. Tibiae I and II with three pairs of long, over- 

 lapping spines beneath. Spines of metatarsi I and II similarly three pairs be-
