 puis clavatis singidis instncctce. Loiig. 2'5 ')nm. 



Head, — As long as the combined length of the ineso- and meta- 

 thorax. The eyes as usual in the genus. 



Antennce. — Equal in length to the furcula (in some examples 

 slightly shorter than that organ). The joints related to one 

 another in length as 5 : 8 : 9 : 13. 



Tnmk. — Invested with scales, among which are prominent 

 curved set^e, ciliated at their apices akmg one side, and disposed 

 in the following manner : a prominent '' frill "or " collar " along 

 the anterior border of the mesothorax, and a second group of such 

 setfe near the posterior margin of that segment. A few scattered 

 setfe on the metathorax, and a tuft of similar but shorter setse 

 at the extremity of the abdomen. The segments related to one 

 another in length as 8 : 6 : 5 : 5 : 5 : 23 : 5 : 3. 



Legs. — The claws of the feet similar on all pairs of legs 

 (fig. 41). The superior claws modei-ately slender, slightly curved 

 at their extremity, and armed with three minute teeth along the 

 inner margin. The inferior claws lanceolate, entire, slightly 

 curved at their apices. A single tenent hair in relation to each 

 foot. 



Furcula.— In length measuring '8 mm.; the inaiiubrium re\s,ted 

 to the denies in length as 13 : 19 — or approximately as 2:3. 

 The denies without ventral scales ; slightly curved upwards at 

 their apices (fig. 42). The mucrones only imperfectly separated 

 off from the dentes, armed with a pi-oniinently curved terminal 

 tooth and a basal spiniform tooth. The latter directed back- 

 wards in an oblique fashion, almost reaching to the apex of the 

 mucro (fig. 42). 



Coloration. — Dirty yellowish white, mai-ked with ii-regular 

 patches of blue-black disposed in the following manner : — A 

 prominent patch on either side of the head enveloping each 

 eye-group, and united by a. transverse band, which ci-osses 

 the head immediately behind the bases of the antennae. A. 

 slender Y-shaped marking on the middle of the dorsal aspect 

 of the head. A pair of irregular lateral patches on the meta- 

 thorax and on the first three abdomiiml segments ; the third 

 abdominal segment with a median unpaired patch near its 

 posterior bordei'. The fourth abdominal segment marked with 

 several irregular lateral and median areas partially confluent with 

 one another, and varying in different specimens ; a short trans- 

 verse band near the posterior end of the segment. The fifth 

 abdominal segment with a pair of prominent lateral patches near 

 its posterior margin. The sixth abdominal segment with a pair 

 of small lateral spots. 



The legs, antennae, and furcula yellowish white, similar to the 

 ground colour of the body. The antennae and legs conspicuously 

 marked with blotches of blue-black ; in one very dark example 

 these markings on the antennje were confluent, the latter 

 appearing entirely blue-black.
