the eye, but so concealed by dense yellow pile that it cannot be measured satis- 

 factorily ; face very wide, with long yellow pile (mixed a little with black 

 above on one specimen) ; structure of antenna, face and mouth-parts as given 

 above in generic characters ; the yellow pile of face continues below to the 

 occiput, but there is a line of black hairs immediately behind the eye. 



Thorax shining black, showing through the pile over the middle ; scu- 

 tellum with long and dense yellow pile, which forms a long fringe behind. 



Abdomen thick, rounded, shining black or with a tinge of violet, with 

 dense, erect black pile not as long as the thoracic ; four distinct ring-like seg- 

 ments, the fifth and sixth together somewhat disklike, and bearing anteriorly 

 the clasping organs, which are normally concealed well forward in the venter. 



Legs black, of moderate stoutness, black-haired except the basal part of 

 the femora ; claws black, pulvilli dark brown. 



Wings strongly infuscated along the veins, and especially in the region 

 from the anterior crossvein to the costa. Length, 14 mm.; of wing, 12 mm. 



Three males, collected by Mr. Wm. T. Davis on White-Face 

 Mountain, in the Adirondacks, New York; July 6 and 10, 1914. The 

 type and one paratype are returned to Mr. Davis, the other paratype 

 remains in the collection of the describer. 



Mr. Davis lived at the base of the mountain for some days, making 

 almost daily ascents to the summit ; he says, " Along the trail there 

 were several open places where the sun shone warmly, and where 

 we found many insects, and I think the botflies." From the general 

 resemblance to some woolly Syrphids (Criorhina verbosa, Eristalis 

 flaz'ipcs), the botflies were not recognized at first as important, hence 

 the exact locality was not remembered. 



The figures in the plate have been retouched to bring out the 

 yellow pile, which showed but little in the print. 



MISCELLANEOUS NOTES. 



Silpha surinamensis and Creophilus villosus as Predaceous Insects. 



— While at Wilmington in 1914, Mr. Ernest Shoemaker and I heard 

 that a neighbor had killed a porcupine that had been found investi- 

 gating an outhouse. We secured the animal and carried it to a nearby 

 wood to serve as a bait for insects. 



On the morning of July 11 we found many Silpha surinamensis, 

 Silpha americana and Creophilus villosus about the remains. It 

 was raining at the time. On the way home I visited the spot with
