REPORT OF THE STATE ENTOMOLOGIST I912 81 



earlier reared Phormia larvae. The maggots were placed in a 

 fruit jar containing earth and remained moderately active and in 

 the larval condition till the 25th, at which time a few recent pu- 

 paria were found. Most of the maggots were then at the bottom 

 of the soil in the jar and not on the surface, as was the case with 

 many of the Phormia larvae. The Sarcophagid larvae trans- 

 formed slowly to puparia and no flies were reared till September 

 15th, others appearing on the i6th and 17th. 



Summarizing, an examination of material shows that the first 

 stage had nearly passed before the maggots were observed. The 

 second larval stage lasted about four days and the third three days, 

 the prepupal condition persisting for about six days and the in- 

 sects remaining in puparia 22 to 23 days. 



Description. First stage. Length 2 mm, diameter .3 mm, 

 whitish, slender, hardly tapering anteriorly, subtruncate poster- 

 iorly, the segmentation distinct and marked with a series of trans- 

 verse bands of short, dark, chitinous points. The cephalo-pharyn- 

 geal skeleton is very similar to that of Phormia, the mandibular 

 sclerites are slender, nearly rectilinear; the stomal plates rather 

 large, the teeth irregular; hypostomal sclerites slender, slightly 

 curved, lateral pharyngeal sclerite transverse, broad, and with 

 tapering dorsal and ventral processes posteriorly, the former being 

 somewhat longer ; the dorsal sclerite is slender, strongly lobed and 

 unites the two lateral pharyngeal plates ; posterior spiracles ap- 

 parently with two weakly chitinized openings. 



Second stage. Length 5 to 6 mm, diameter .6 to i mm, whitish, 

 slender, tapering slightly to the anterior extremity. Cephalo- 

 pharyngeal skeleton : mandibular sclerites heavy, rather strongly 

 decurved, basal portion broadly triangular ; dental sclerite short, 

 stout, strongly curved, free ; hypostomal sclerite moderately short, 

 stout, and united with its fellow by a broad, chitinous bar ; lateral 

 pharyngeal sclerites, anterior portion broadly transverse, subrect- 

 angular and with long ventral and dorsal processes posteriorly, 

 the latter somewhat longer and more tapering; posterior spiracles 

 each with two, moderately .chitinized, orifices. Cuticular chitiniza- 

 tion mostly equally bidentate. 



Third stage. Length about 16 mm, diameter 2^ to 3 mm, 

 whitish, slender and tapering from the obliquely truncate poster- 

 ior extremity to a slender apex. Cephalo-pharyngeal skeleton : 

 mandibular sclerite stout, decurved, the basal portion with a tria- 

 angular lobe ventrally ; dental sclerite short, irregular ; hypostomal
