IXJUEIOUS AND BENEFICLIL INSECTS. 263 



The larva (fig. 17) is long and slender, with a rather small 

 head, which is a little over half as wide as the 

 segment (prothorax) next to it ; it is somewhat 

 trapezoidal in form being widest in front, a 

 little longer than broad, with black, conspicu- 

 ous eyes consisting of four or five raised facets. 

 The stout, minute anteuuje are two-jointed, the 

 joints being of equal thickness, the second a 

 little shoi-ter than the first. The upper lip 

 (labrum) is small, transversely broad ovate, 

 with the front edge rounded. The jaws are _. „ ^ ,

quite small. The maxillae are very large, ob- "Lady-bird.- 

 tuse cylindrical, projecting far beyond the head. The labium 

 is small and short. 



The body is widest on the third segment behind the head, 

 and shorter than the first segment, the three segments gi-ad- 

 ually decreasing in length ; while the abdominal segments 

 are nearly equal in length, and very convex laterall3^ The 

 form of the terminal (ninth) segment I could not make out, 

 as all my specimens were preparing to affix themselves to the 

 surfiice of the leaf, and this segment was greatly enlarged and 

 elonirated, ending in a soft and membranous ruflle-like dilata- 

 tion by which the insect was evidently about to gum itself 

 to the leaf. 



The body is covered with short, stiff hairs. It is white, 

 with two dark spots on the segment next the head, fom- on 

 each of the two following segments, and two on the five suc- 

 ceeding segments ; these spots are thickened portions of the 

 skin, giving rise to hairs. The legs are stout, the toe-joint 

 endhiiT in a siujrle claw, with four or five tenant hairs at the 

 end of the joint. Length about a seventh (.15) of an inch. 



The pupa is of the usual form in the group, but is white, 

 with two faint dorsal dark spots on the middle thoracic 

 segment, and two on the basal segment of the abdomen ; far- 

 ther behind is a pair of large, converging, black spots begin- 

 ning on the second abdominal segment, and ending on the 

 fourth ; while on each side of the fourth are two dark spots. 

 There are two slight dorsal spots on the fifth segment. The 

 body is usually provided with a few fine, scattered hairs, but 

 in a very small specimen (.06 inch long) the upper side is
