124 ENTOMOLOGICAL NEWS. [October, 



of tibiae and all of tarsi indigo-blue; femora with a row of strong spines. 

 One specimen with all colors much deepened, and some minor differences, 

 may prove to be distinct. Length about 2 mm.; 3 mm. to end of hemilyta; 

 breadth one-third the length. 



Described from many specimens. Taken in Illinois from leaves 

 of apple, hop, walnut, bean, and some 'weeds. I regret to add 

 another to the long list of apple pests, but I am compelled to do 

 so from observations repeated during two seasons. The speci- 

 mens were taken from May until after heavy frosts. Their inju- 

 ries to the apple leaves were plainly to be seen, the leaves being 

 discolored wherever a puncture had been made. An account of 

 its injuries appears in the Lacon. (Illinois) " Fruit Grower" vol. 

 i, p. 132, July, 1890.- 



I take pleasure in dedicating this beautiful little species to my 

 highly esteemed friend, Miss Emma Bird, who has greatly aided 

 me in entomological work for several years.

WHAT CAN IT BE? 



BY MRS. JULIA P. BALLARD, 

 Eastern, Pa. 



On the i2th of September, 1889, a large "mulberry" colored 

 caterpillar was given to me. Its food-plant was not known. It 

 was very strong and very snappish. There were two pairs of 

 spined horns, one pair on the third and one on the fourth ring, 

 and a strong sharp-pointed spined horn at the end. His whole 

 length was marked by diagonal lines of the same mulberry color, 

 but of a darker shade. These radiated from the central line down 

 his back just like the veinings of a leaf. He was fully three in- 

 ches in length, quite as large as the caterpillar of the Royal Dryo- 

 campa (C. regalis}. No food offered him proved satisfactory. 

 He resented the slightest disturbance with a sudden, quick mo- 

 tion, jerking about as if in a fury of passion, but kept quite still 

 if not disturbed. I at once recognized him as the same kind of 

 caterpillar I once secured nearly ten years ago. 



" I saw an immense caterpillar, as I was coming up the hill, 

 fully three if not four inches long," said a friend coming in one 

 hot June day. 



" Why didn't you bring him along?" was the quick response. 



" I had no box, and I dare not touch him." 



Seeing me don my hat and take up a pencil and parasol, said: 

 "You will not find him; he'll be sure to have gotten away,"
