dorsal shieid is distinctly visible. — Shape like otker inales, esp. 

 L. lepidopeltis Klti ; the body is sinuated outward above the 

 rostrum, above the coxae 1 and 2 and between the legs 3 and 4. 



Dorsal side (Fig. 8). The dorsal shieid is broadest on the shouklers, 

 tapering rapidly toward the apex, slowly backward, with rounded 

 posterior margin. This margin forms a crescent shaped free blade 

 above the dorsum, like in L. corethroproctus Oudms. The wrinkles 

 of the soft skin run under this free blade. The hairs on the dorsal 

 shieid are nearly the same in number as well as is position as 

 on the two dorsal shields and on the intermediate space of the 

 nymph. Moreover the dorsum is almost hairless, showing only 

 almost invisible hairs ou the posterior part of the abdomen. 



Ventral side (Fig. 9). Between the bases of the maxillae and 

 the mentum there is a part distinctly scaly, consequently a shieid. 



1 will call it mentonal shieid. Between the mentum and the sterni- 

 genital shieid there is a praesternal shieid. Then follows the 

 sterni-genital shieid, with two anterior and two lateral corners, 

 directed toward the part between coxae 1 and 2, and between 



2 and 3. Five pairs of little hairs are planted on the margins of 

 this shieid. The anterior margin is excavated to receive the genital 

 aperture. The posterior margin is rounded. The ventri-anal shieid 

 consists of a ventral and an anal part, both loug and triang- 

 ular with top backward. Aside of this shieid there are numerous 

 little hairs. 



The peritrema (Fig. 8 and 9) immediately runs dorsalwards 

 and remains there, following the edges of the dorsal shieid till 

 above the coxae 1. 



The epistoma (Fig. 8) is pointed anteriorly. lts sides are first 

 almost parallel, then tapering toward the end. 



The mandibles (Fig. 10) show a curious distally truncated 

 immovable finger, which is denticulate on its end and bears a 

 very sinall knob, probably a rudiment of a dog-tooth. The movable 

 finger is a strong crooked hook, without any teeth, but provided 

 ventrally and outward with a somewhat boat-shaped appendage 

 (copulation organ) which looks like that of L. lepidopeltis Klti. —
