Foem. " Facies du K. horridum, sauf les cuisses qui ne 

 sont pas renflees, la taille qui n'excede pas 22 lignes, et la 

 couleur qui varie de cendre au roux, avec une lisrne longi- 

 tudinale, brune sur le dos. Deux epines sur la tcte, quatre 

 sur le prothorax en deux rangs ; quatre de chaque cotd 

 sur le mesothorax, et trois doubles en Y entre elles ; six 

 sur le metathorax et deux en dessous. Une triple rangee 

 sur les cinq premiers segments de 1'abdomen. Une seule 

 petite epine sur le milieu des sixieme et septieme. Cuisses 

 legerement epineuses. Antennes moins longues que celles 

 du male. 



" Cette espece a de grands rapports de forme chez le 

 male avec les Bacteries, mais ses nombrenses epines et la 

 forme de la femelle, que je suis bien sur etre la sienne, le 

 doivent placer a cote du K. horridum. Je l'ai appele' 

 Scorpionides a cause de Phabitude qui le nude a de re- 

 courber sa queue en haut comme les Scorpions."

Ilab. Lord Howe's Island (D. Macgillivray). B.M. 



Male pitchy, slightly varied with chestnut, and glossy ; 

 female more chestnut-coloured, with the sides more luteous. 

 The head is almost square, marked in the female with a 

 dark cordate spot between the eyes, and six longitudinal dark 

 stripes on the hinder part ; in each sex there are two minute 



punctures on the front part of the crown. The antennae ex- 

 tend to the extremity of the fore tarsi. The prothorax is some- 

 what larger than the head, the mesothorax twice the length 

 of the prothorax, and the metathorax about three-fourths 

 of the length of the mesothorax, but wider, with the sides 

 swollen, especially in the male, and armed with small spines. 

 The abdomen in the male is narrower than the thorax, 

 with the sides nearly parallel ; it is as broad as the thorax 

 in the female, with the segments gradually attenuated from 

 the middle to the tip ; it is bright chestnut-coloured, very 

 glossy, with the six basal segments varied with small irre- 

 gular black spots arranged in two series on each side of 

 the median line, and an oblique impressed line on each side. 

 The male has the body beneath pitchy, glossy, destitute of 

 tubercles, and with the margins of the abdominal segments 

 paler luteous. The under side of the body of the female 

 is glabrous, destitute of tubercles, paler luteous-chestnut, 

 with the middle and hind part of the presternum, the hind 

 part of the mesostemum, and the middle of the meta- 

 sternum darker chestnut. The terminal segment of the 

 body is truncate in the male, with the outer angles pro- 

 duced, and armed beneath with minute transverse teeth ; 

 it is also notched in the middle, and is furnished beneath 

 with two small oval lobes ; the three terminal ventral seg- 

 ments in this sex are simple. The terminal segment of the 

 abdomen in the female is small, suboval, emarginate in the 

 middle. The operculum extends beneath and beyond the 

 three terminal segments. The four anterior legs are nearly 

 similar in size in both sexes, but the hind pair in the male 

 have the femora enormously dilated, carinated above and 

 toothed beneath ; the tibiae greatly bent, and shutting upon 

 the femora beneath and between the strong teeth ; the two 

 hind femora in the female are but slightly thickened and 

 spined beneath. 



A young specimen of the female in the British Museum 

 Collection measures 2} inches in length, and has the oper- 

 culum not extending beyond half the length of the ninth 

 dorsal segment. It agrees in general form with the full- 

 grown female, except in being somewhat more slender.
