respects similar to 9 . Described from 1 $ 5 9 specimens, bred from Euplectrus 
comirtockii at Selma, Ala. 
This species seems to belong to Thomson's third section of the genns Elachistm. 
Note 34 (p. 107).— Except in lacking the two bristles at the apes of the third seg- 
ment of the abdomen which are prominent in sarracenim (type), and in other species, 
tli-- specimen differs in no respect from those fonud to infest the Rocky Mountain 
I. list and Caloptemi8 differenlialis (Locust Plague, &c, pp. 135,136; and First Ann. 
Rep. U. S. Ent. Comm., p. 324). Although in the works here cited sarravenice is con- 
sidered a variety of the common European 5. camaria it seems best to maintain it as 
a distinct species in accordance with the characters given by Mr. R. II. Meade, who, 
in his "Monograph upon the British species of Sarcophaga or Flesh-tly " (Ent. Mo. 
Mag., vol. xii, p. 216 ff., Febr.-May, 1*76), separates the species into two principal 
divisions, according as the tip of the abdomen is red or is black or gray. In a note 
published in Baron Osten Sacken's Catalogue of the described Diptera of N. A., 2d 
ed., p. 257, Mr. Meade says: "There is no specimen in your collection, however, ex- 
actly like the true S. carnaria so common in Europe. There are some striking points 
of difference between the Sarcophaga? of America and Europe generally, the chief of 
which is that in the former species with one or both anal segments red or yellow pre- 
dominate, while among the latter, those with the anal segments black or gray are 
mom nnmerous than those with the reel." 
The following additional specific characters may be added: Thorax with four bris- 
tles behind the suture in the two dorsal rows, the two anterior bristles small, the two 
posterior strong; in front of the suture are two small bristles alternating with two 
of slightly larger size. There are no minute spines ou the second longitudinal vein 
similar to those on the fourth. The posterior tibireof the $ are loosely bearded on 
the inner side with long soft hairs. The second abdominal joint is not armed with 
strong central spines, and the spines at the apex of the third joint are short and weak. 
Notk 3") (p. 10'.)).— Taciiina aleti.e Riley (Can. Ent., vol. xi, p. 162).— Length 
8 mm . Black; head golden, facial depression silvery, space between the eyes and the 
frontal sti ipe about equal to the breadth of the stripe, bristles of the head black, the 
pubescence behind and beneath the eyes white; antenna- blackish, palpi testaceous. 
Eyes at a moderate distance apart, thinly pubescent; front moderately prominent; 
third joint of the antenna 1 three or four times the length of the second joint. Thorax 
and the second and following abdominal joints more or less ashy, the thorax with 
four or five longitudinal black stripes. Wings subhyaline. Legs black, with a 
piceous tinge; tarsal cushions yellowish. Scutellum and the sides of the first, sec- 
ond, and third abdominal joints sometimes tinged with reddish-brown. No strong 
bristles on the first and second abdominal joints above. 
Note 36 (p. 100). Taciiina fkaterxa Comstock (Annual Report of Commissioner 
of Agriculture, 1879, p. 303). — Color : General effect nearly black ; head, face, and facial 
depression silvery white, inclining slightly to golden on occiput ; antenna?, first and 
third joints black, second joint testaceous ; palpi testaceous ; pubescence behind the 
head blackish; thorax, second and following abdominal joints ashy ; thorax with two 
plain longitudinal black stripes and two indistinct ; first abdominal joint black above, 
ashy beneath; femora piceous; tibia? and tarsi nearly black. Eyes finely pubescent. 
In other respects resembling T. aletice Riley. Described from two specimens. 
Note 37 (p. 110). — The Tachinid larva differs from that of Sarcophaga in the follow- 
ing characters: It is of a paler whitish color, the skin being softer or less chitinized; 
the body is less narrowed anteriorly ; the prothoracic spiracles are less apparent; a 
pair of spiracles are present on the posterior border of the fourth joint behind the 
head, which are not discoverable in Sarcophaga; the joints are not conspicuously 
wrinkled transversely and there are no lateral prominences, the auterior portion of 
each joint being prominent and roughened with minute points; the spiraeular cavity 
at the end of the body iB more shallow, the spiracles being exposed upon the obliquely 
truncated area, and there are no anal prolegs. The Tachinid puparium may be readily
