SECRETARY'S REPORT.

are five to six inches from tip to tip, (measured from specimens 

 in the State Cabinet.) The wings are of similar texture and 

 color to the preceding, but with larger and coarser markings, 

 and frequently spotted with milky white dots. The mandibles 

 of the male are extremely long and tapering, often measuring 

 an inch or more from base to tip ; those of the female scarcely 

 a quarter of the length, but strong, thick, and furnished at the 

 tip with four teeth. The antennae of both are moniliform, or 

 like a string of beads, and much the longest in the male. The 

 body is dark brown above, spotted and streaked with yellow ; 

 the feet and under side lighter. Figure 32 represents a 

 female of medium size. Figure 33 the larva, 

 which is aquatic and found oftenest in mill- 

 ponds. It is of a blackish color, marked with 

 yellow somewhat like the perfect insect, and 

 with branchial or gill-like organs on the sides 

 of the abdomen. 



Polystcechotes (from poli/, many, and stoi- 

 chos, a row,) is represented in this State by 

 one species only, the punctdtns of Fabricius, 

 (figure 34, Harr.,') signifying spotted or 

 speckled. This insect is easily distinguished 

 by the peculiarly regular veining of the wings, 

 somewhat resembling the strings of a musical 

 instrument. The body is blackish above, lighter beneath, eyes 

 rather prominent, feet yellowish, fore-wings hyaline, spotted

with fuscous and cinereous, or ashy ; hind-wings very slightly 

 marked on the margin, and hyaline in the centre, bordered 

 with a very narrow black fringe interrupted with whitish. The 

 larva is supposed to live like those of the preceding species, in 

 the water. 



The genus Chrysdpa of Leach, (meaning golden-eyed,) and 

 commonly called " lace-wings," comprises several species bear-
