J^S YCHE.

middle division of the plate. The penis 

 is curved downward, armed with two 

 sharp teeth, hollow beneath ; below it 

 arise two sharp slender accessory spines. 



The beautiful brown or delicate pink 

 tints, and the unusual multiplicity of ring- 

 like discal and peridiscal spots, add to 

 the bizarre nature of this form. 



Larva spiny. " The larvae feed grega- 

 riously and are of a brownish green with 

 black spines. The eggs are laid on the 

 young green stems at the top of the tree 

 (Dialiutn gicincense), and the pupae are 

 found under the food-tree, lying on the 

 surface beneath leaves." *' 



Beutenmiiller describes the larva as 



being armed with black spines along the 

 back and sides on "i, 2, 3, 11 and 12 

 segments." Remaining rows of spines 

 yellow (green) tipped with black, with 

 the spinules also tipped with black." 

 (Journ. N. Y. Ent. Soc, v. p. 166, 1897). 

 From his description we judge that the 

 larva is armed with spinulated spines, 

 hence it does not belong with the Uro- 

 tinae, the larva of Urota being smooth- 

 bodied in its final stage. It appears to 

 be nearer to the Biinacinac, whose lar- 

 vae in some cases have spinulated spines, 

 and perhaps the group has arisen from 

 that phylum. 



TWO NEW SPECIES OF OPHION. 



BY E. P. FELT, ALBANY, N. Y. 



The members of this genus are ex- 

 tremely difficult to characterize in an 

 entirely satisfactory manner and the 

 descriptions of these two forms have 

 remained unpublished for several years 

 on this account. 



O-phlon (Etiiscopilus) arcuatttm sp. nov. — 

 Light fulvo-ferruginous, the larger opaque 

 chitinous spot of the cubito-discoidal cell 

 with a distinct arcuate continuation extending 

 along the hinder margin of the glabrous area 

 and partly around the smaller chitinous spot. 



Head medium, yellowish posteriorly, face 

 yellowish, antennae slightly longer than the

body; ocelli black, equidistant ; mandibles bi- 

 dentate, fusciis apically. Thorax, sericeous; 

 meso-thorax, convex; scutellum and post- 

 scutellum, prominent, the former yellowish; 

 meta-tlior.ix, slightly depressed in front of 

 the transverse carina ; lateral carinae distinct. 

 Wings hyaline, having hardly a trace of the 

 fuscus visible in Opiiion (Em'scopilus) fiiyga- 

 ium Sav; marginal nervure slightly thickened 

 and sinuate near the small stigma; cubito- 

 discoidal nervure, weakly sinuate, not appen- 

 diculate ; its bulla 4 the width of the third 

 discoidal cell from its apex ; two sub-triangu- 

 lar opaque spots in the glabrous area of the 

 cubito-discoidal cell, the larger one with a 

 chitinous, usually yellowish continuation 

 along the hinder margin of the glabrous 

 area to a point beyond the sinaller chitinous 

 spot, which latter is anterior and lateral of 

 the center of the glabrous area. Legs, honey
