species or even races. Now, to adopt races in the sanie straw- or 

 haymagazine should be to bold. 



Mandibulae (Fig. 23) with stroug jaws; upper jaw with two 

 incisors of which the first slightly larger than the second, with 

 two canine teeth, with the same rule; and with three tubercles 

 which together form a strong molar. Lower or movable jaw with 

 two incisors of which the first is smaller than the second, two 

 canine teeth with the same rule ; no molars. 



Maxillae (Fig. 24). Coxal parts of course fused to form the so- 

 called underlip or hypostome. Trochanter, femur and genu coalesced 

 with hypostome, yet their demarcations are discernible. Tibia and 

 tarsus free; the first with a hair proximally, the latter with 3 

 minute pins distally. 



Legs. Dorsal side (Fig. 21). Trochanter I with the pseudo-stigma 

 and the bifid, feathered hair. Genu I and II proximally with two 

 densely hairy hairs which sometimes reach the tarsus. Genu I 

 distally with a small olfactoric and a small tactile hair. Genu II 

 distally only with an olfactoric hair. Tibia I and II distally with 

 a long tactile hair, which reaches far beyond the ambulacra. Tarsi 

 I and II proximally with 3 olfactoric hairs, of which the middle 

 one is the longest (see also fig. 25 a, b, d), and distally with a 

 minute hair. — Genu III, tibia III and tibia IV distally with a small 

 tactile hair. Tarsi I and II shorter, tarsi III and IV longer than 

 the remaining joints of the correspondiug leg together. The tarsi 

 are fianked by a row of extremely minute hairs, which belong to 

 the subtarsal scale. — Ventral side (Fig. 22). Coxal plates I and 

 IV with a small smooth hair. Trochanteres I and II with a thin 

 hairy hair, which reaches the tibia. Tibiae I and II distally with 

 a densely hairy hair, which reach beyond the middle of the tarsus. 

 Trochanter III in the middle with a densely hairy hair, which is 

 directed outward. Genu III proximally with a ditto hair directed 

 outward. Tibia III, femur IV and tibia IV in the distal half, inward, 

 with a ditto hair, directed inward. All the tarsi have proximally 

 a scale resembling in shape and in fastening a scale of a Lepi- 

 dopteron, however without the known striation; this scale is as
