SCIENCE- GOSSIP. 



anterior row of eyes is never less than the second 

 row. 



Trochosa ruricola Degeer. {Lycosa campestris 

 Bl.) 



Length. Male 9 mm., female 13 mm. 



The palpus of the male is terminated by a short 

 claw, and the fang of each falx has a small knob- 

 like projection on its outer side. A very common 

 species. 



Trochosa robiista Sim. 



Length. Male 10 mm., female 15 mm. 



May be distinguished in the male sex from 

 T. ruricola by the absence of the projection upon 

 the fang. Very rare. 



Trochosa terricola Thor. (Lycosa agretyca 

 Bl.) 



Length. Male 7 mm., female 12 mm. 



This species may be distinguished from the fore- 

 going by the absence of the terminal claw of the male 

 palpus. It is common. 



Trochosa spmipalpis F. Cb. 



Length. Male 8 mm., female 10 mm. 



The radial joint of the male is furnished with a 

 number of stout spines towards its fore extremity on 

 the inner side. Rare. 



Trochosa leopardns Sund. {Lycosa canibrica 

 Bl.) 



Length. Male 7 mm., female 9 mm. 



This species may be distinguished by the extremely 

 narrow digital joint of the palpus of the male. Not 

 common. 



Trochosa cinerea Fabr. {Lycosa allodroma Bl. ) 

 Length. Male 16 mm., female 17 mm. 

 Allied to T. leopardus, but easily distinguished by 

 /eason of its large size. 



Trochosa picta Hahn. 



Length. Male 7 mm., female 8 mm. 



The digital joint of the male palpus is very narrow, 

 but not so much so as T. leopaj-dus. It may be dis- 

 tinguished from that species by the brilliantly coloured 

 abdomen. It is not uncommon. 



Trochosa hiunguiculata Cb. 

 Length. Male 8 mm. 



Digital joint terminated by two short claws. Very 

 rare. 



GENUS TARENTULA SUND. 



The spiders of this genus are not by any means 

 sharply separated from Trochosa. In the present 

 case the anterior row of eyes is never longer, but is 

 usually shorter than the second row. The clypeus, 

 too, is usually higher than in Trochosa. 



Eyes of anterior row equally separated. This row 

 is distinctly shorter than the second. Not uncommon. 



Tarentula cuneata Clk. 



Length. Male 6 mm., female 8 mm. 



Closely allied to T. piilvcriilenta, but the tibiae ot 

 the anterior legs of the male are dark and swollen. 

 Rare. 



Tarentula accentuata Latr. {Lycosa an- 

 drenivora Bl. ) 



Length. -Male 8 mm., female 9 mm. 



This species may be distinguished from T. piilvent- 

 lenta by the distance between the anterior central 

 eyes being greater than that between one of them 

 and the adjacent lateral. Not uncommon. 



Tarentula fabrilis Clk. 



Length. Male 12 mm., female 15 mm. 



This spider may be at once recognised by its large 

 size. The anterior central eyes are larger than the 

 laterals, and the anterior row is almost as long as the 

 second. A very rare species. 



Tarentula aculeata Clk. 



Length. Male 9 mm., female larger. 



Very nearly allied to T. pulveruhnta, but the legs 

 compared with the cephalo-thorax are considerably 

 longer. The whole spider, too, is much larger than 

 T. pulveruleuta. Very rare. 



Tarentula trabilis Clk. 



Length. Male 9 mm., female larger. 



The humeral joint of the male palpus is furnished 

 with a longitudinal row of black bristly hairs. Ex- 

 tremely rare. 



Tarentula miniata Koch. 



Length. Male 5.5 mm., female larger. 



Cephalo-thorax dark brown, with a broad central 

 and narrow marginal reddish-yellow bands. Femora 

 of legs distinctly annulated. A local species. 



GENUS LYCOSA LATR. 



■ Par do s a Sim.) 



BLl 



Tarentula pulverulenta Clk. {Lycosa rapac^ 



Length. Male 6 mm., female 9 mm. 



The spiders of this genus may be recognised by the 

 almost perpendicular sides of the caput. The clypeus 

 is high, and the legs are long and considerably at- 

 tenuated towards their extremities. The Lycosae are 

 extremely active spiders, usually found running upon 

 low herbage, dead leaves, or even upon the bare 

 ground. The females carry their lenticular egg-sacs 

 attached to the spinners. 



Lycosa amentata Clk. (Z. saccata Bl. ) 

 Length. Male 6 mm., female 8 mm. 

 Anterior central eyes somewhat larger than the 

 laterals. Palpi of male very dark. Radial and 

 digital joint clothed with coarse black hairs. Near 

 the centre of the palpal organs is a curved, sharp- 

 pointed spine. This species is very common and 

 widelv distributed.
