SOME INSECTS INJURIOUS TO TRUCK CROPS. 



leaden gray, and of old mounted material a duller gray, thickly dif- 

 fused with black and b^o^Yn dots and other markings more or less con- 

 stant, forming irregular lines across both fore-wings and hind-wings. 

 On both there is a marginal regular scalloped black line and within 

 this a strongly dentate or zigzag white line. The general pattern of 

 the wings varies considerably from that shown in figure 6, a, which 

 represents the female. The color of the body is similar to that of the 

 wings. The first abdominal segment is white above. 



The sexes can be readily distinguished by the antenna^. Those of 

 the female are filiform and tessellated and those of the male rather 

 strongly pectinate, or feathered. The structure of the latter is siiown 

 at e and /, figure 0. 



" It may be known," says Packard, " by the very distinct line at the 



base of the abdo- 

 men, the basal 

 wing be^^ond be- 

 i n g usually 

 white, and the 

 underside of the 

 wings having a 

 broad marginal 

 shade, while the 

 third line on the 

 f o r e - w i n g is 

 deeply but quite 

 regularly sinuate 

 and near the 

 costa acutely 

 dentate." 



A number of 

 synonyms are 

 credited to Gle- 



ora jyampinaria. It has indeed received five specific names. As three 

 of these were given by Guenee, it is of itself indicative of the varia- 

 tion of the moth. The list follows :

The egg appears not to have been described. 



The larva. — The larva resembles those of other geometrids in being 

 of elongate form, about nine times as long as wide, Avith the three 

 pairs of thoracic or front legs bunched closely together near the head, 

 and in having only two pairs of prolegs, or unjointed legs, at the
