FII?ST ANNUAL REPORT OF THE STATE ENTOMOLOGIST. 



tion within, the anterior portion. When the grubs were taken from the 

 mold, they extended their front segments like the pushing out of an 

 introverted glove-finger, and made a moderate degree of progress over 

 the paper on which they were placed, by the aid of several pairs of 

 small, low, flattened ventral tubercles, bearing on their circumference a 

 number of closely-set, radiating spinules — these organs serving the 

 purpose of legs. 



From the fact that the larvfe did not go into pupation until about a 

 month after their reception, it maybe presumed that during this time 

 they fed upon the mold in which they were buried. If this be so, then 

 it does not seem necessary to doubt that the place in which they were 

 discovered was that in which their earlier larval stage had been passed. 



Pupation. 



Several times between February 9th and 13th, the larv^ emerged 

 from the mold, and traveled restlessly about the jar in which they were 

 confined, as if seeking a more agreeable or suitable retreat. Finally 

 they remained upon the surface, being no longer able to bury in the 

 mold. On the 16th of February it was evident that their pupal change 

 was in progress. They had contracted materially in size, and become 

 more pointed behind. The front segments assumed a darker shade, 

 and of these the first two segments were of a blackish 

 color. The two respiratory horns on the dorsum over 

 £"^"^1 the second pair of leg-tubercles had become more promi- 

 nent, and were now about one-twentieth of an inch long. 

 The tube containing the respiratory seta was dark brown. 

 An irregular-shaped packet of excremental matter was 

 attached to the anal orifice. 



The pupation was brief — twelve days in one example 

 (a male), and fourteen in the other (a female). The 

 flies emerged from their pupal cases, which were left as 

 thin shreds within the puparia, by rupturing the latter 

 in a line above the mouth-parts and again just back of 

 the respiratory horns, and forcing off an oval piece : in 

 one example the horns continued attached to the 



puparium. 



The Puparium. 



Fig. 63 represents the puparium as seen from above, 

 in double its natural size. The respiratory tube is 

 clearly seen to consist of three portions, of which the 

 main part is more corrugated and grannlose than shown 

 in the figure. Laterally, seven slightly projecting black 

 spiracles may be seen with a lens — one over each leg-tubercle. Ventrally
