INSECTS INJURING OAK-LEAVES. 179 



250. Catocala polygama Guen^e. 



This species Las been bred from the oak by Professor Riley, and the 

 following description has been drawn from the blown specimen in his 

 collection. The caterpillar pupates in a loose cocoon among leaves. 



" May 7, 1872. About full-grown ; found under shelter at foot of 

 black jack oak. Color preserves well. Some paler than others. They 

 lie very flat on the twigs. 



" It prepared for pupation May 10, and changed to pupa May 16, 

 the moth issuing June 6.'' (Riley's unimblished notes.) 



Larva.— Body of the usual shape, with no spines or large tubercles. Head as 

 usual, black on the sides of the front and vertex. Body ash brown, lineated, with 

 two broad dark dorsal stripes, succeeded below by a narrower but similar stripe. 

 Sides of the body above the base of the legs dark ash. On each abdominal segment 

 are four light, distinct, small tubercles, and four on each side arranged in a rhom- 

 boid. A row of large black ventral patches edged with orange ou each segment, 

 becoming largest between the first and second pair of abdominal legs. Length 65™">. 



Pupa. — Of the usual form, the body frosted over with a whitish powder. Length 

 25™"\ 



Moth. — The four wings slightly greenish gray, powdered with dark ferruginous 

 scales, especially beyond the outer line, where this shade forms a dentate submar- 

 ginal line. The outer or extradiscal line is more finely waved, and above the sub- 

 median vein it passes into a black spot bordered with rust-red. The edge of the 

 hind wings are indented with yellow at the outer angle. 



251. Catocala coccinata Grote. 



The caterpillar of this moth has been bred from the oak by Mr. D. 

 W. Coquillett, of Illinois. His specimen si^un its cocoon June 6, pro- 

 ducing the imago the 30th of the same month. 



Larva. — Body dark gray, a curved fleshy proiection on top of segment 8 ; segment 

 11 slightlj' raised, with two tubercles on the top; a row of small prickles on the 

 dorsal space, sixteen legs, a black spot beneath each of the segments which bear the 

 four pairs of abdominal legs; head gray, bordered with black. Length 62™™. 

 (Coquillett.) 



Moth. — A little smaller than C.parta ; clear cinereous ; before the reniform, which 

 is smaller and paler than in C. parta, the wing is whitish and occasionally allows 

 the crimson underfacc to be reflected. Subreniform spot whitish and large. Hind 

 wings bright crimsou. (Grote.) 



The following species are geometrids, or species of the lepidopterous 

 family Phalcenidce : 



252. Eutrapala clemataria Hiibner. 



The caterpillar of this moth occurred on the live oak at Crescent 

 City, Fla., in April. My specimens were left to be bred in the office of 

 the TT. S. Entomologist, at Washington, but died. The following notes 

 were copied for me by Mr. Pergande. 



The larva had not eaten anything for some days when received, and drank 

 greedily some water when placed near some drops, and soon after commenced feed- 

 ing on leaves of white and other oaks. ~It cast a skin two or three days after and 

 became quite dark brownish. It died April 27 of diarrhea.
