narrow yellowish, white stripe ; and three similar, somewhat broken stripes 

 extend along the venter. There are man)' small, slightly elevated, black 

 spots on the body, from which arise short brownish hairs. Near each spiracle 

 there are three of these spots ; one in the yellowish-white stripe just ven- 

 trad of the spiracles ; one in the edge of the dark portion of the dorsum, 

 and the third spot slightly caudad or caudo-veutrad of the spiracle. The 

 dorsal surface of each segment bears four of these spots ; on the thoracic 

 segments and the anal segment they are arranged in a row across the mid- 

 dle of the segment, but on the remaining eight abdominal segments the 

 four spots are arranged at the angles of a square. On the ventral surface of 

 the thoraic segments and the eighth abdominal segment there are six spots 

 arranged in a row across the middle of the segment, the two inner spots 

 being quite near each other. Across the middle of the ventral portions of 

 the first and seventh abdominal segments there is a row of eight spots, and 

 on the anal segment there are four spots similarly placed. The ventral por- 

 tions of the second, third, fourth, and fifth abdominal segments bear ten 

 spots each, arranged as follows : — four spots margined with a yellowish-white 

 ring, two each side on a fold of the body just ventrad of the yellowish-white 

 stripe below the spiracles ; three spots on each side of the mesal line and 

 arranged at the angles of a triangle. The sixth abdominal segment has 

 four of these spots on its ventral surface, two near the base of each pro-leg. 

 Two pairs of pro-legs are present, borne by the sixth and last abdominal 

 segments. The true legs and pro-legs are sparsely hairy and nearly the 

 same color as the venter. Spiracles, black with brownish centre, the one 

 on the prothoracic segment being the largest. 



IV. INSECTS INJURIOUS TO CURRANT. 



A LEAF-ROLLER ON CURRANT. 



Cacoccia rosana. 



Order Lepidoptera ; family Tortricidae. 



A small green worm fastening together the terminal leaves of currant into 

 an irregular shaped wad, within which it lives and undergoes its trans- 

 formations. 



In addition to the common, well-known pests of the currant, 

 several species which infest that plant but are found less frequently, 

 are being studied at this station. One of these is a common 

 European moth known to entomologists as Cacoecia rosana. This 

 insect has been introduced into this country ; and judging from 

 the number of specimens of the adult moth that are found in va- 

 rious collections, the species is common here in some places. But
