Fam. Sicariidae. 
Genus Sicai'ius Walck. 
1. Sicai'ius testaceus n. sp. 
Specimens. 3 $$ and I juv. from Kamaggas, Little Namaqualand, July 1904. 
Colour testaceous, the abdomen paler. 
Cephalothorax broader than long, its vvidth equal to the tibia and % — l /. z of the patella and to 
the metatarsus and %— 8 A of the tarsus of first leg, and only slightly shorter than the patella and tibia of 
fourth leg. Upper surface beset with a number of swollen infuscate or black hairs of various shapes and 
symmetrically arranged, each leaving a circular scar when removed; the lateral borders of the thoracic 
portion with a rovv of these hairs, which are here slightly curved forwards, obtusely pointed at the apex but 
for the most part not clavate, those at the hind angles several deep and about twice as long as the more 
anterior ones ; anterior margin of head with a row of similar but straighter and often subclavate hairs ; rest 
of the upper surface with a number of short, stumpy, mostly clavate and blacker hairs arranged in sym- 
metrica! groups as follows: On the posterior convexity of the head 2 longitudinal groups of 6 — 8 hairs each, 
on the anterior part of the head behind the ocular area 4 longitudinal rows of several hairs each, and on 
the thoracic portion on each side 4 or 5 groups of hairs; between the larger hairs a number of minute 
swollen hairs are thickly scattered over the upper surface. 
Median e y e s slightly less than a diameter apart, the lateral eyes about a diameter apart. 
Abdomen with a number of erect, strongly curved, clavate, infuscate hairs with their curved ends 
for the most part directed towards the median line, these hairs arranged in symmetrical bands and groups, 
the Spaces between them evenly studded with minute swollen hairs ; on the dorsal surface 6 such rounded 
Spaces surrounded by clavate hairs are evident, 3 on each side in a longitudinal row, with a narrow longi- 
tudinal space down the median line connected with each of the rounded spaces by 3 narrow transverse 
spaces; behind these Spaces are several transverse Spaces lying between the transverse bands of clavate hairs 
at the hind end of the abdomen. 
Legs thickly covered with minute spinules and with numerous larger swollen dark hairs and spines; 
femora with 2 rows of short rod-like hairs or spines below, the dorsal edge of each femur with a row of 
4 large, narrow, oblanceolate, pointed, white hairs placed at equal distances apart on black tubercles and 
strongly contrasting with the other dark hairs, etc. ; the more distal segments of the legs strongly and 
sharply spined below. 
Length 7V4 mm. 
The hairs on these specimens are remarkably well-preserved. 
2. Sicarius albospinosus n. sp. 
Specimens. a) 5 ex. from Lüderitz Bay (Angra Pequena), Great Namaqualand, April 1903 and 
January 1904. 
Colour pale-yellow, the cephalothorax of a darker yellow than the legs and abdomen. 
Cephalothorax broader than long, its width equal to the length of the tibia and from % to 
slightly over V 2 the patella and to that of the metatarsus and 3 / i — 5 / 6 of the tarsus of first leg, and equal to 
or less than the length of the patella and tibia of fourth leg. Upper surface beset with numerous minute 
spinules and a smaller number of short, rod-like, mostly curved, obtuse spines, which do not for the most 
part form such distinct groups as in the previous species, but are more evenly scattered about; on the head,
