process having a short pointed spine in contact with its base^ on 

 the inner side, and have a strong obtuse process in front ; these 

 processes and the spine are of a dark-brown colour tinged with 

 red. 



The large brown-black spots in the medial line of the upper 

 part of the abdomen of both sexes are commonly bisected, and 

 form two distinct longitudinal rows. 



Adult and immature females and an adult and immature 

 male of this species were comprised in the collection. Adult 

 females and an immature male of Artema convexa have been 

 received from Pernambuco. On a comparison of the dimensions 

 of females from Africa and South America, the African specimens 

 will be found to be somewhat the larger, and to have longer legs,

The cephalothorax is slightly compressed before, rounded in 

 front and on the sides, convex, glossy, with an indentation in 

 the medial line of the posterior region; it is of a brownish-yel- 

 low colour, with a broad brown band extending from each lateral 

 pair of eyes nearly to its base. The eyes, which are seated on 

 black spots, are disposed on the anterior part of the cephalo- 

 thorax in two transverse rows ; the four intermediate ones form 

 a square, the two anterior ones being rather the largest of the 

 eight ; and those of each lateral pair are placed obliquely on a 

 small tubercle, and are near to each other, but not in contact. 

 The falces are conical, vertical, armed with a few teeth on the 

 inner surface, and of a brownish-yellow hue, the extremity being 

 the darkest. The maxillae are somewhat quadrate, having the 

 exterior angle, at the extremity, curvilinear; the lip is semi- 

 circular, and slightly pointed at the apex ; and the sternum is 

 heart-shaped. These parts are of a dark-brown colour, the 

 extremity and inner margin of the maxillse, the apex of the lip, 

 and a broad band in the middle of the sternum, which is pointed 

 at its posterior extremity, having a brownish-yellow hue. The 

 legs are long, slender, and of a pale-yellow colour, the extremity 

 of each joint being tinged with brown; the first pair is the 

 longest, then the second, and the third pair is the shortest ; 

 each tarsus is terminated by three claws ; the two superior ones 

 are curved and slightly pectinated, and the inferior one is in- 

 flected near its base. The palpi are short, rather paler than the
