HYMENOPTERA.

and were eurled on tlie leaf. They eat out the edge of the 

 leaf of the butternut tree. Sometime during August, two 



cocoons were spun between the 

 leaves, but I did not succeed in 

 raising the saw-fl}'. On describing 

 the larva, in a letter to Mr. E. Nor- 

 ton, he kindly sent me alcoholic 

 specimens of larvae (without the 

 woolly substance, which dissolves 

 and disappears "in alcohol) found 

 feeding on the hickory, which are 

 apparently, from the comparison of 

 alcoholic specimens, identical with the Butternut Selandria. 

 The adult fly (Fig. lol, S , a^ cocoon), he has named 8. caryce, 

 of which he has kindly furnished 

 me with the subjoined description.* 

 AHantus is closely related to Se- 

 landria, both in its structure and its 

 habits, but differs in having the an- 

 tennae short and somewhat clavate. 

 A. basilaris Hay is a common species. 



The Pine saw-lty, Lophyrus, raay be known by the feathered 

 antennae of the male. L. abietis Harris (Fig. 152, female) 

 infests the fir and pitch-pine. The male is black above and 

 brown beneath, while the female is j-ellowish brown above.

* Selandria carj/a Norton, nov. sp. (Belonging to tribe 3. Under wings with one 

 middle tell. Div. A. Antennre fdiforni, short). 



Female. Color shining black. The pro- and mesothorax and scntellnm rnfous. 

 tlic ajf)ex of the latter black; the nasus and legs white, Mith their tar.?i blackish; the 

 base of coxre and a line down the ui)per side of the legs black. Antennaa short, 

 the second joint as long as the first; the fonr fnial joint.s together, not longer than 

 the two preceding. Nasns slightly incurved. Claws of tarsi apparently bifid, 

 Wings snbviolaceous. Lanceolate cell pctiolate, the first snbniedial cell above it, 

 with a distinct cross vein. Under wings with one snbmarginal middle cell (all 

 other species have this cell discoidal), the marginal cell with a cross nervure, ami 

 all the enter cells closed by an outer nervure, which docs not touch the margin. 

 The snbniedial cell extended nearly to margin. Length, .2."> of an inch. Expanse 

 of wings .40 of an inch. 



" The male resembles the female, but the under wings are without middle cells. 

 The larva; feed upon the leaves of the hickory (Jnglans squamosa.) They are 

 found upon the lower side of the leaf, sometimes fifteen or twenty upon one leaf, 

 which they eat from tlie outer extremity inward, often leaving nothing but the 

 strong midribs. They cover themselves wholly with white floccnlent tufts which 

 are nibbed off on being touched, leaving a j^reen twenty-two legged worm, about .7.">
