of the color than the thorax, and has a hght stripe which extends 

 lengthwise on the mid dorsal surface. Newly hatched larvs 

 varied from 1.32 to 1.5 mm. in length. They are elongate, some- 

 what flattened dorso-venfrally, and taper gradually caudad. 

 The maximum width of the body is near the middle of the head. 

 The three main divisions of the body are well marked. 



The head, which is the most prominent part of the body, is 

 strongly chitinized and wider than the adjacent thoracic segment. 

 It is ovoid in outline, having a length of about 0.53 mm. from 

 the base to the tips of the mandibles and a maximum width in 

 the region of the bases of the mandibles of approximately 0.35 

 mm. A pair of black, irregularly shaped eye spots are present 

 on the dorsal aspect just caudad of the bases of the antennae. 

 The most striking feature of the head is the pair of curved, strong 

 mandibles (Figs. 1 and 5) which extend far beyond the anterior 

 margin of the head. The tips are bent mesad and each bears 

 on the distal part of the inner margin several very small tooth- 

 like projections. Each also bears a number of bristles on its 

 outer margin. The antenna (Figs. 1 and 3) are borne on the 

 dorsal aspect of the head and attached immediately above the 

 bases of the mandibles. Each is composed of eight segments as 

 follows: a strong, cylindrical, basal segment is followed by five 

 similar narrow segments which are closely set together; the 

 penultimate segment is elliptical in outline, distinctly larger and 

 broader than the adjacent ones, and bears two or three bristles 

 on its distal crown; the ultimate segment is cylindrical and 

 approximately as long as the penultimate segment, but the 

 diameter is much smaller. It also bears several bristles on its 

 distal crown and is terminated by a strong spine which is ap- 

 proximately half as long as the segment. Figure 3 shows the 

 structural details and the characteristic shape of the antenna. 

 On the ventral side of the head the gulo-mental region is slightly 

 depressed below the level of the genas. From this side of the head 

 is best seen the rather prominent pair of palpi, apparently the 

 maxillary palpi, which extends cephalad almost to the tips of the 

 mandibles. Each is composed of five segments, the distal one of 

 which bears a number of short, stout spines. The middle seg- 

 ments also bear two or three long bristles. The head as a whole 

 bears on the dorsal and ventral surfaces scattering bristles.
