ART. 2 LARVAE AND PUPAE OF THE FAMILY LEPTIDAE GREENE 13 



CHRYSOPILA, species 



Plate 1 



Habits. — Larvae appear to be scavengers. They are found under 

 dead leaves on the ground in the woods and also in the wet frass in 

 tree holes. 



Larva {fg. 7). — Large, white, cylindrical, elongate, smooth; first 

 two segments tapering slightly to the small head; 11 segments in 

 addition to the head. Head (fig. I) small, its dorsal portion with 

 faintly impressed lines, giving the surface a slightly rugose appear- 

 ance; the frontal portion of the head (fph) is heavily chitinized, the 

 chitin is reddish yellow, and is divided into a right and left half, 

 each half ter*minating in an arcuate row of large, elongated teeth; 

 seen from above, the head is divided antero-medianly by an elongate, 

 keel-shaped- plate (pi) which is compressed below ; on each side of 

 this plate is an elongated, triangular area, covered with reddish 

 yellow spines pointing upward and slightly backward; laterally, is 

 a small oval elevation upon which is located the antenna; this is 

 white, cylindrical, single jointed, slightly larger at the base and 

 with its length about five times its diameter; mandibles (md) tri- 

 angular, robust, heavily chitinized, reddish-yellow ; maxillary palpus 

 white, smooth, cylindrical, its length about four times its diataeter. 

 On each side of the ventral surface of the head are two small bristles. 

 First 10 segments are of equal length; the integument along each 

 segmental line is raised into 5 to 7 transverse rows of slightly flat- 

 tened ridges and each ridge is divided into short scale-like partb of 

 unequal length. Anterior spiracle (fig. 7?t) small, slightly elevated, 

 yellow, located on the side of the first segment, oval in outline; the 

 center with a small, circular white spot, and two small oval depres- 

 sions posterior to this spot ; last segment slightly rounded, tertai- 

 naring in four pointed, flattened lobes, the under surface of which 

 is yellowish and slightly rugose; these lobes have a short j^ellow 

 fringe of hairs around the edge, and each lobes has a large bristle 

 in the middle of its inner face just before the apex; between the 

 upper and lower lobes is a large conical tubercle pointing backward; 

 on the side of last segment are several well defined, linear depres- 

 sions; anal opening in the middle of the venter of last segment, 

 located on a large, rounded, rugose elevation. Posterior spiracle 

 (fig. n) is situated at the base of each upper lobe; it is heavily chit- 

 inized, reddish yellow, and in outline elliptical with a slight dorsal 

 concavity; the peritreme is divided into 40 equal parts which are 

 pointed distally, and proximally at their bases is a row of short, 

 radiating, raised lines; in the center of the spiracle is a transverse, 

 sinuous depression.
