Length : 6 2 ram. ; ? 2-2 mm. 



We have a series of this species taken off spirit specimens of Roussettus collaris 

 from Cape Colony, and another series off Roussettus atramineus from Knysna, 

 Cape Colony. 



2. Ctenophthalmus ansorgei spec, now 



? . This species is similar to C. caucasica Tasch. (1880). The rostrum is rather 

 short, being about two-thirds the length of the forecoxa. There are three genal 

 spines. The pronotal comb consists of sixteen teeth. The mesonotnm bears two 

 rows of bristles and numerons short hairs on the back. There are three rows on the 

 metanotnm, besides an abbreviated fourth row. The epimernm of the metathorax 

 bears six to eight bristles. The abdominal tergites have three rows of bristles, 

 the first row consisting of a few hairs only, except on the first tergite, the row 

 on this segment extending nearly as far down as the second row. The seventh 

 tergite bears three apical bristles, the upper one being two-fifths and the lower 

 one two-thirds of the length of the central one. The sternites of segments 3 to 6 

 bear one row of bristles and ventrally a small number of hairs in front of this row, 

 these additional hairs being arranged in a row on the posterior sternites. 



The legs are the same as in C. caucasica. 



Modified Segments. — ?. The seventh sternite (Fig. 2) has a deep but rather 

 narrow sinus, the upper lobe being much narrower than in C. caucasica. The 



eighth tergite bears six or seven long bristles and several short ones, as shown 

 in the figure. The aual sternite bears four bristles on each side. 



Length : 2-8 mm. 



We have two ? ? taken off Georychus bocagei by Dr. W. J. Ansorge at Bihe, 

 Angola, on November 21st, 1904. 



3. Ctenophthalmus triodontus spec. nov. 



<??. Distantly related to C. caucasica Tasch. (1880); distinguished by the 

 modified segments of the abdomen, the tarsi, and the bristles of the abdomen. 



Head. — There is a comb of three spines at the ventral edge of the gena. 

 The frontal portion of the head bears two rows of bristles, the anterior row 

 containing four bristles and the second row three long ones. 



Thorax. — The pronotal comb consists of sixteen spines. The metathoracic 

 epimernm bears from eleven to thirteen bristles. 



Abdomen.— There are two rows of bristles on the tergites, the first tergite 

 bearing in addition a few dorsal bristles representing a third row, the following 

 tergite also bearing one or two additional bristles. The seventh tergite has three
