 " 29, 6 " — bees less activ^e; sunset at 8.40. 

 " 30, 7-8 a.m. — a few bees. 



" 30, 5 p.m. — ^no flowers open, several bees at old ones; old flowers 

 removed from three plants. 

 " — 5, 5, and 6 flowers open on the 3 plants; bees active. 

 " — 9, 18, and 13 flowers open on the 3 plants. 

 " — 2, 6 and 2 flowers open on the 3 plants. 

 " — 0, and flowers open on the 3 plants; no bees. 

 This shows clearly that the main period is from one to two hours before 

 sunset. Some plants of Anogra pallida were watched at same time. Three 

 flowers opened at 9 p.m., but no visitors were seen in the next half hour. One 

 specimen of Aiitographa falcifera Kby., apparently the moth referred to (F.nt. 

 News 31:43), was taken at Gaura in the evening, two of Rhodophora florida Gn., 

 at Anogra in the morning (det. by Henry Skinner and deposited in the Acad. 

 Nat. Sci. collection).

A NEW GENUS AND A NEW SPECIES OF SPIDERS IN THE GROUP 



PHRUROLITHE^. 



BY RALPH v. CHAMBERLIX, 

 Cambridge, Mass. 



Phruronellus, gen. nov. 

 Proposed for a group of species heretofore included in Phrurolithiis. The 

 males are characterized by having near the proximal end of the femur, or some- 

 times at the middle, beneath, a conspicuous but short apophysis which is usually 

 bent at the end, in place of the simple swelling at the distal end of femur present 

 in species of Phrurolithus sens. str. Also by having the tibial apophysis with 

 two distinct prongs united at base. The cephalothorax is more nearly circular 

 in outline, the head region less narrowed, and differing in being uniformly dark

shiny chestnut or blackish, without any definite markings such as are present in 

 Phrurolithus. First legs without the tibiae conspicuously black, as in the latter
