tapering; veiUral pair a litile longer than the longest ventral hairs, dorsal 



pair one-third as long again as the ventral pair. 



Observatio?ts. — The larva of this species superficially closely resem- 

 bles the foregoinfj, and still more those of A. hemisurus^ Dyar and Knab. 

 The last named has no rows of spines on the antenna, the comb scales are 

 without spines, having only sette, and the compound hairs in the tube are 

 above the pecten rows. According to Dyar and Knab's table and figure 

 (from N. Y. Ent. Soc, Vol. XIV), it would seem to be near A. tormentor, 

 D. & K., a mainland species. 



Mochlostyrax Ja7naicensis, nov. sp. — 9 • Head with pale yellow 

 flattened scales at the middle and sides, many long black forked scales at 

 the back, each of these irregularly frayed along the upper expanded 

 border. Some long black hairs among the other scales. Proboscis black, 

 swollen at the apex, speckled with yellow scales, tip yellow. Palpi black, 

 the terminal joints yellow scaled. Eyes with white 

 borders posteriorly. Clypeus dark brown. Antenna / 

 dark brown, joints with scattered brown hairs, these are 

 rather larger and arranged in a ring below each clear 

 area, suggesting a double set of verticellate hairs. Pro- 

 thoracic lobes black, somewhat prominent, coveied with 

 fine scales and long black hairs. Mesothorax black, 

 with two dark brown median bands anteriorly. Surface 

 covered with fine hair-like scales, a row of long black 

 hairs on each side of the mid line, another row at the 

 edse near the prothoracic lobes, and a group in front of ,^'^'- '^°-~^ochio- 

 the insertion of the wing. Scutelhim dark brown, with sp—^.'^'-^r from comb; 



^ ' I), nook from tube. 



fine scales, six long bristles on the posterior border of 

 the mid lobe, and four on each of the lateral lobes. Metanotum dark 

 brown. Pleura grayish, with a line of black bristles down each side to 

 the mid coxae, a cluster of bristles anteriorly between the front coxae, 

 several small patches of white hairs below the insertions of the wings. 

 Abdomen black, and speckled with dull white scales, the latter denser at 

 the bases of the segments, forming a pronounced band at the base of the 

 second segment, long white hairs along the posterior borders of the 

 segments. Small lateral white scaled areas on the sixth and seventh 

 segments formed by the extensions of the white ventral bands. Venter 

 with broad crescentic basal bands of silvery scales. Legs black, ventral 

 surfaces of the femora white, except at the extreme apices, where there are
