Maine. As the larva is not figured in Bulletin No. 172 some de- 

 tails will be figured and described here. The larva is white in 

 color, 12 segmented, slender and legless. The head is yellow- 

 ish brown, oblong, about twice as long as wide, the labrum has 

 a rounded margin, setose ventrally. The mandibles are brown, 

 margined with a number of teeth and with a toothed claw on 

 the inner side (figs. 41, 42) ; the lateral comb of the epipharynx 

 has 6 teeth (fig. 39) ; the labium has several smaller as well as 

 two larger -ones and its lateral margins are fringed with long 

 hairs (fig. 38). The maxilla is shown in figure 40. There are 

 a few scattered bristles on the head and two eye spots. The 

 two miain tracheal trunks end in the thoracic spiracles (fig. 43) 

 on the center of the lateral margin of the first thoracic segment 

 and extend to the apex of the twelfth abdominal segment; they 

 are connected by a strong commissure at the anterior end of 

 the second thoracic segment. The length of the full grown 

 larva is about ^4 oi an inch. 



The pupa is brown ; tapering, with a few spines on thorax 

 and abdomen projecting backward; length 1-6 of an inch. 



TiPULiDAE (Crane flies). 



Two crane flies from Maine may be noticed at this time as 

 being of particular interest. The one, Ctenophora apicata, be- 

 cause of its rarity, and the other because of possible economic 

 interest to potato and apple growers. 



Ctenophora apicata. 



Nine males and six females of this handsome crane fly were 

 reared from larvae and pupae found in the decaying wood of 

 an elm tree. They were collected at Orono, Maine, June 23, 

 \>y Mr. William Woods. Though this species is not of eco- 

 nomic importance still it may not be out of place to give here 

 :a brief description owing to its rarity. The male appears never 

 to have been described. 



The full grown larva is white, cylindrical, over ij/g inches 

 long. The head is black, well formed, oval, 3-64 of an inch 

 in diameter and twice as long; apparently only the apical fourth 

 can be exserted. The antennae are cylindrical with an apical 

 papilla. On the dorsal surface of the head at some distance
