484 FIFTH KEPORT OF THE ENTOMOLOGICAL COMMISSION 
tion," be Bays, k> was drawn to the spot by finding a Rkyssa kumida (Say) 
with its ovipositor firmly driven into the wood. Upon catting into the 
Btick, this specimen, together with a pnpa of the male and several horn- 
taile larva, were found. The antenna? of the pnpa are bent down upon 
the sides of the face and up along the back of the head. One of the 
larv;r changed to papa (female, length 0.32 inch) on the -1st of July. 
The male agrees well with Norton's description as given in Trans. Am. 
Ent. Soc. (ii, p. 354), and is very unlike the female." (Can. Ent., xi, p. 
14, 1879.) 
Male. — '' Falf honey yellow, antennae 16 jointed, blackish, two or three basal arti- 
cles yellowish ; a spot inclosing ocelli, tip of mandibles, Bides of neck, of iueso, and 
metathorai blackish; tergnm irregularly dark; pectus brown piceons; body beneath 
and legs whitish ; wings hyaline, nervures and stigma pale; under wings with two 
middle cells. Pennsylvania." (Norton.) 
Female. — " Head and thorax black ; tibiae and tarsi pale; wings hyaline ; abdomen 
red, with six yellow spots. Length 0.40 inch, expanse of wings 0.64 inch. 
"Antennae 16-jointed, black, piceous beneath, especially toward tip. Face below 
and bptweeu antennae, palpi, and base of mandibles, fulvous. Eyes, except for a 
short space above, bordered with yellow, the border covering nearly the whole cheek 
and the anterior and posterior borders, extending backward to meet on the edge of 
the occiput, thereby inclosing a spot above the eyes, which is black in the center 
but shading through piceous into the yellow borders. Space about the ocelli finely 
rugose, with delicate ridges radiating from each ocellus; vertex behind the ocelli 
polished. A pit or deep puncture midway between the lower ocellus and the inser- 
tion of the antennae. Thorax closely and finely rugulose ; scutellum and inclosure 
on tbe basal plates polished. Tegulae, minute spots before the tegulae, one each side 
above the anterior wing, and the cenchri, yellow. Trochanters, tips of coxae and of 
femora dull yellow ; femora piceous, posterior pair black ; basal half of tibia- and 
basal joints of tarsi, except at tip, yellow T ; the remainder of tibiae and tarsi fulvous, 
becoming brownish on the posterior tibiae. Wings hyaline, iridescent, nervures and 
stigma pale piceous. Basal half of the first segment of the abdomen black and 
roughened with fine confluent punctures; the remainder of this segment and portions 
of the terminal segment are darker than the other segments of the red polished abdo- 
men. A yellow spot on each side of segments 3, 4, and 7, those on the seventh seg- 
ment being the largest. Sheath of the ovipositor black ; abdomen beneath, except 
at base of ovipositor, red." (Patton.) 
2. Tremex columba Linn. 
Order Hymenoptera ; family Urocerid.e. 
Mrs. Dimmock gives the following summary of its history (Psyche, iv, 
p. 285) : 
Tremex columba Linn. (Syst. Nat., 1758, ed. 10, p. 929). Harris (Rept. Ins. Injur, 
Veg., 1841, p. 389-391) describes the egg, larva, aud imago of this insect, giving wood 
of pear, Ulmw, and P/ataHM«asfood of the larva; and(Entom. Corresp., 1869, p. 360) 
again describes the egg and imago. In Amer. Eutom., Nov., 1868, v. i, p. 59, this 
species is mentioned as injuring oak and pear trees. Packard (Guide Study Ins., 1869, 
p. 228) quotes Harris's accounts of the habits of this species. Huggius(Amer. Entom., 
Feb. 1870, v. 2, p. 128) found this insect ovipositing in an apple tree. Packard (Bull. 7. 
U. S. Entom. Comm., 1881, p. 105, 106) figures the larva, which he states to attack 
llmu8, Quercus, Acer, and Platanus ; aud {op. cit., p. 129) says, "In yellow birch at 
Providence," R. I. Harrington (Can. Entom., Dec, 1882, v. 14, p. 225) gives some 
notes upon this species and adds Fagus to the food-plants.
