CATALOGUE OF INSECTS. 387 



P. achemon Dru. With the preceding and on the same food plants : not 

 rarely attracted to light. The larvae are easily recognizable by the 

 absence of the horn and by the retractile anterior segments, a character 

 also found in the next genus. 



AMPELOPHAG-A Brem. & Gray. 



A. chcerilus Cram. Common throughout the State, V to VIII. According 

 to Brehme eggs are found V and VIII and the larva; feed from 20 to oD 

 days. The usual food plants are grape and Virginia creeper ; but they 

 also live on sour gum, Azalea, Viburnum, sheepberry, &c. 



A. myron Cram. Common throughout the State, VI-VIII, and is sometimes 

 attracted to light. Eggs are found, V, VII, VIII (Br). The larva feeds 

 on grape and Ampelopsis. 



A. versicolor Harr. G. d., but very local and rarely in numbers, V-VII. 

 There are two broods and the larva feeds on button-ball ( Cephalanthus 

 occidentalism and Nesaa verticillata. 



Sub-family SPHINGINJ2. 



DILOPHONOTA Burin. 



D. ello Linn. A visitor from the South, occasionally in some numbers, taken 

 by the Newark collectors. The larva in Florida feeds on Euphorbia 

 (Dyar^. 



The record of D. obscura has proved unreliable and the species is therefore 

 omitted. 



PROTOPARCE Burm. 



P. celeus Hbn. Throughout the State, VI-IX, though rarely common. 

 Larva on potato and similar plants ; occasionally injurious. Remedies 

 are hand picking or Paris green in the earlier stages. 



P. Carolina Linn. Throughout the State, VI-IX. The larva is the "tomato 

 worm " of Southern New Jersey, and does considerable injury each year: 

 it is less common northwardly and occurs also on potato and other plants 

 of the same natural family. Remedial measures as before. 



P. rustica Kabr. I took a single specimen near Union Hill years ago, and 

 have no other records of its capture. The State is well within the faunal 

 range of the species and it should occur where the food of the larva 

 Chionanthus and Jasminium, occurs. 



P. cingulata Fabr. Generally distributed ; but nowhere abundant. The larva 

 feeds on morning glory, sweet potato and other Ipomica and Convolvulus 

 species until late in fall. Mr. Brehme records finding a full-grown ex- 

 ample on morning glory, October 10. 



SPHINX Linn. 



S. kalmiae Sin. and Abb. Lyons Farms, VI (Br), Newark, V, 12, VI, 2, 8, 

 VII, 6 (Sb), Staten Island, VIII (Ds), g. d. Mr. Brehme finds larva- in 

 VI-VIII on ash : other food plants are lilac, laurel and Chionanthus.
