tile anal spiracles distinctly upon the surface of the subtruncated posterior end, not 

 situated in a cavity as in Sarcophaga; just beneath these spiracles is a slight transverse 

 elevation. 



The pupariom of Belvmsia hi/asciata differs somewhat from the ordinary form. It is 

 black, roughened, increases in width posteriorly, has the anal spiracles drawn far for- 

 ward upon the back, and each represented by three swollen tubercles, and the space 

 between them and the tip of the puparium is very irregular and has a conspicuous 

 transverse depression. 



Note 38 (p. 111). — Cryptus conquiaitor, Say {Bost. Jour., i, 232), of which, as Walsh 

 {Canadian Entomologial, ii, 12) pointed out, Cryptus pleurivinctua, Say (1. c, 235), is a 

 synonym. By some oversight pleurivinctus stands as a synonym under annuUoarnia, 

 Cress., instead of conquisitor, in Mr. Cresson's List of the North American PiinplarioB 

 {Trans. Am. Ent. Soc, iii, 170). 



Note 39 (p. 114). — The name Cryptus extrematis Cress, should yield to C. samias 

 Pack., because two species (one of which is nundns) were combined under it in the 

 original description. 



Note 40 (p. 115). — We gave the following description of the larva and pupa of 

 Chalcis ovata in the first edition of this report : 



The larva is a slender legless maggot, 7«*™ in length. The body tapers at each end, 

 particularly behind, and has a conspicuous lateral ridge. The head is similar to that 

 of the Pimpla larva described further on, but the mandibles are nearly concealed, be- 

 ing covered by the other mouth parts. The first three joints of the body are separated 

 by deeper constrictions than the succeeding joints, and the lateral tubercles on joints 

 4-10 have a smaller but distinct tubercle behind them. The spiracles in the alcoholic 

 specimen are indistinct, owing to their agreeing with the skin in color ; but their 

 position is apparent upon the anterior border of the second, third, fourth, and several 

 of the posterior joints. Length 7""™. 



The pupa is short and robust ; pale at first but becoming brown, the head and thorax 

 anteriorly darker. It has two prominent tubercles between the eyes just above the 

 insertion of the antennse, and above each of these a slight ridge extending as high 

 as the lower ocellus, which is situated on a slight prominence within the fork of 

 an impressed line on the vertex. Only five distinct joints in the antenna© between 

 the scape. 



In addition to Desmia mavulaUs, and the two species of Apatura mentioned in the 

 text, we have bred this parasite from Thyridopteryx epliemeratformis (Haw.), Caeceda 

 rosaceana (Harr.), Geleehia gallas solidaginis, Eiley, and Botis alnialis Riley MS. (See 

 Bulletin 5, United States Department of Agriculture, Division of Entomology, p. 8.) 

 The species is very variable in size, and we have specimens as small as 3™"* in length 

 while others measure as much as 6""^. 



Note 41 (p. 115). — This species {Tetrastichus esurus, Riley) was treated in the first 

 edition under the generic name Cirrospilus, and in the original description {Canadian 

 Entomologist, xi, 162), it was also placed in that genus, but only provisionally, and 

 we there called attention to its close relationship with Tetra$tiehui. Since receiving 

 more abundant and better material, and after a closer study, we haye decided that it 

 should be placed in the latter genus. We reproduce the original description : 



Length 1.5™™. Dull black; knees, tibiae, and tarsi yellowish; the posterior tibiae 

 sometimes dusky. Eyes with scattered short bristles. Antenn» of the^ 9-jointed, 

 with the joints of the flagellum subequal and beset with bristles, the ninth joint 

 small. Antennae of the 9 8-jointed, the fourth and fifth shorter than the second o,nd 

 third, the three apical joints forming a club. Thorax above microscopically punctate ; 

 parapsides distinct and elevated ; scutellum with a longitudinal impressed line on 

 each side. Wings hyaline, pubescent, but the cilia short; base of ulna uneven; 

 radius not developed. Abdomen short and sessile; ovate. — (Can. Ent., xi, p. 162.) 



Note 42 (]3. 115). Hexaplasta zigzag. — We reproduce the original description of this 

 species : 



Average length 1.6^^^. Body uniformly polished black. Legs, palpi and antennae 

 reddish in the female ; coxaj, femora, and antennae toward tip infuscate in the male. 

 Peduncled joints of antennae with a few minute spines around the crown, and longi-
