extremity, and of a pale yellowish brown colour. Lip nearly 

 quadrate, dark brown at the base, but paler at the apex. Ster- 

 num almost circular, with blackish spots on the margins, and a 

 longitudinal streak of the same shade extending from its anterior 

 part, on each side of the medial line, more than half of its length. 

 Legs long, slender, provided with hairs and sessile spines ; they 

 are of a pale reddish brown colour, the femora of the anterior 

 pair being dark brown at the base ; each tarsus is terminated by 

 three claws ; the two superior ones are curved and pectinated, 

 and the inferior one is inflected near its base. The humeral joint 

 of the palpi is dark brown ; the cubital and radial joints are red- 

 dish brown, the latter, which is much the stronger, being abun- 

 dantly supplied with black hairs; the digital joint is brown, of 

 an oblong oval form, convex and hairy externally, concave within, 

 comprising the palpal organs, which are moderately developed, 

 not very complicated in structure, rather prominent, with a short, ' 

 projecting, pointed process near the outer side, and are of a 

 brownish black colour tinged Mdth red. The concavity of the 

 digital joint does not extend to its termination, which is compact. 

 Abdomen slender, oviform, convex above, projecting a little over 

 the base of the cephalo-thorax ; it is of a light orange-brown 

 colour, with an irregular band of black on each side of the me- ■ 

 dial line ; these bands converge towards the spinners, where they 

 meet, and on the anterior pai't of the light orange-brown space 

 comprised between them there is a narrow oval figure of orange- 

 brown circumscribed by a fine black line ; the sides are spotted 

 with brownish black, and a longitudinal line composed of con- 

 fluent spots of the same hue occurs on each side of the under 

 part, the intermediate space being densely covered with white 

 hairs. ' 



This species was captured in June at Interlacken in the can- ■ 

 ton of Berne.
