INSECTS OF THE PRICKLY ASH. 661 
approached they usually go deeper in, if possible. I uever took one 
by beating on the bushes. I saw one on the trunk of a prickly ash, 
but it escaped by falling to the ground. 
The beetle. — In the genus Micracis the funicle is six-jointed; club pubescent and 
annulated on both sides, outer joints of funicle slighter broader, not fringed ; elytra 
aculeate at tip. 
Iu this species the club of the antennae is more than one-half longer than wide ; 
the gular space between the eyes is wide ; the punctures of the elytra are fine and 
arranged in numerous distinct rows ; there are a few short hairs near the tip in some 
specimens, but iu others even these are wanting. Length, 2.5 mm (.10 inch). 
3. The hog caterpillar of the orange. 
Papiho cresphontes Fabr. 
Order Lepidoptera ; family Papilionid^e 
The following account of this caterpillar, which is said by Mr. Barnes 
(Psyche, iii, p. 162) to feed on the hop tree, is taken from Professor 
Coinstock's report for 1880, also Mr. Hubbard's report on Orange 
Insects, who states that it " is found commonly in the swamps of 
Florida, feeding upon the tupelo (Nyssa aquatica L.) and upon the 
red bay* (Persea carolinensis Nees.) It seems, however, to prefer the 
orange and its relatives to all other plants." Besides the prickly ash, 
according to Mr. Saunders, it lives on Dictammus fraxinella in Canada 
West (Eept. Ent. Soc. Ontario, 1880). In Texas it feeds on Zan- 
thoxylum carolinianum (Boll, Psyche, ii, p. 289). In southern Illinois the 
prickly ash is its usual food (French). There are two broods in south- 
ern Illinois. 
"In speaking of the caterpillar of this butterfly in his report on orange 
insects (Patent Office Report, Agriculture, 1858, p. 265), Mr. Glover 
stated that it was very injurious to the foliage of the orange. Boisduval 
and Le Conte (Histoire des Lepidop teres et des Chenilles de FAmerique 
Septentrionale 1833) say concerning this caterpillar that it lives upon 
all the trees of the genus Citrus, and is in some parts of America in a 
measure a scourge to the orange growers. I, myself, found several of 
the chrysalides upon orange trees in my recent visit to Florida, and 
since my return specimens of the caterpillars have been sent to the 
department by Mr. G. W. Means, of Micopany, Fla. ; Mr. H. S. Will- 
iams, Rock Ledge, Fla. ; and Mrs. Rebecca A. Minor, of Houma, La., 
all reporting them as doing more or less damage to orange foliage. Mr. 
A. T. Harvey, of Lake Griffin P. O., Sumter County, Fla., informs 
me that he has had many orange seedlings completely defoliated by 
these larvae — ' orange dogs/ as they call them in that part of the 
country." 
The eggs. — Deposited singly upon the leaves; are subglobular in form, some- 
what flattened on the side of attachment, and yellowish white in color after hatch- 
ing. What their color is before hatching we are unable to say, as the only specimen 
received at the Department hatched on the journey. They were sent by Dr. Turner
