PSYCHE.

the apex in the opposite direction. It 

 hears the usual spines at the apex, but 

 the longer inner one is curved beyond 

 the middle. All that remains of the 

 tarsus is a spine-like appendage which 

 takes its place, — an appendage less than 

 one half the diameter at base, about as 

 as long as twice the width of the tibia, 

 tapering slightly, and bluntly rounded 

 at tip. 



The specimen was obtained by the 

 late Mr. F. G. Sanborn, May 10, 186S, 

 in West Roxbury, Mass., and is now in 

 the museum of the Natural history 

 society, Boston. 



Chloeniits tomentosa Say (PI. 2, 

 fig. 3) . The single specimen before me 

 shows a somewhat simple malformation 

 in the left middle leg. The femur and 

 tibia are normal, excepting that the tibia 

 is somewhat more enlarged than natural 

 at the apex, more resembling in this 

 respect the fore tibia, expanding broadly 

 at its extreme apex. Here, besides the 

 normal spurs, there is the attachment 

 of what appear to be a triple series of 

 tarsi. The middle one is reduced to a 

 mere conical bulb between the other 

 two, bristling at its apex with spines of 

 a moderate length ; one of the others 

 consists only of what may perhaps be 

 regarded as the basal half of the meta- 

 tarsus extending at right angles outward, 

 bluntly rounded at the apex, but show- 

 ing at the extreme apex and just at its 

 side the points from which a couple of 

 spines, probably of moderate size, have 

 been broken oft"; the inner is the only 

 developed tarsus, and this is malformed 

 in two ways : first that the metatarsus 



is rather stouter than normal, a little 

 curved, and is followed by a short 

 supernumerary joint only a little smaller 

 than the normal second joint; and 

 second, that the whole tarsus is bent at 

 right angles between the supernumerary 

 joint and the second (this bend is not 

 seen in the figure) ; unless indeed these 

 two joints may be regarded as one, con- 

 stricted and bent at right angles in the 

 middle. 



This specimen was obtained by Mr. 

 F. Stratton at Natick, Mass., and is 

 now in the museum of the Natural his- 

 tory society, Boston. 



La.mpyridae. 



Telephones rotimdicollis Say (PI. 

 7, i fig- 5)* A right antenna in which 

 the first joint is longer than usual ; the 

 second is of ordinary length but as large 

 at base as at apex and bears two joints, 

 one at the apex, a normal third fol- 

 lowed by eight joints as usual, and the 

 other a short, depressed, thickened joint 

 articulated on the apical half of the an- 

 terior face of the second joint, and fol- 

 lowed by five joints, the first of which 

 is like the preceding, while the rest are 

 slender, elongated joints, somewhat like 

 the normal joints but evidently useless 

 and perhaps immoveable (by will) in 

 life, together curling backward. 



In the drawing the normal third bears 

 a curved appendage which I did not 

 see ; and the third joint of the supple- 

 mentary palp, being bent and folded, is 

 represented as if made up of two small 

 joints.
