CDLICID GENUS LEICESTERIA, THEOBALD. 257 



Key for determining the Species. 



1. Female with simple claws; the palpi with a white ring in the 



middle ; all joints of hind tarsi with distinct basal white rings 



annulipalpis, Theo. 

 Female with toothed claws on the front and middle legs ; female 

 palpi without white ring in middle ; if the hind tarsi have pale 

 rings these generally embrace both ends of the joints ... ... 2. 



2. Hind tibiae distinctly shorter than the front ones ; postnotnm 



with a few setae or scales or both ... ... ... jlava, Leic. 



Hind tibiae slightly longer than the front ones ; postnotnm bare 3. 



3. Abdominal segments 4-7 with basal lateral yellow patches, in 



addition to the more apically placed white ones ; hind tarsi 



with more or less distinct pale rings ... ... ... ... 4. 



Abdominal segments 4-7 without lateral yellow patches ; hind 



tarsi and palpi entirely dark ... ... ... ... ... 6. 



4. Clypeus bare ; female palpi all dark ; thorax much produced over 



the head ... ... ... ... ... ... dolichocephala, Leic. 



Clypeus more or less scaly ; female palpi with the extreme tip 



white; thorax not so much produced ... ... ... ... 5. 



5. Yellowish median basal patches on abdominal segments 3-8 or 



5-8 ; the white lateral patches on segments 6 and 7 not quite 

 reaching the hind margins... ... ... ... . .. magna, Theo. 



No yellowish median basal patches on abdominal segments ; the 

 white lateral patches on segments 6 and 7 reaching the hind 

 margins ... ... ... ... ... ... annulitarsis, Leic. 



6. White lateral abdominal patches produced over the dorsum at or 



near the apices of the segments ... ... ... ... ... 7. 



White patches not at all produced over the dorsum, which is all 



blackish ... ... ... ... ... ... ... ... 8. 



7. The lateral abdominal patches become creamy towards the 



dorsum, where they form narrow but complete apical bands 



chujidala, Leic. 

 The lateral abdominal patches do not become creamy dorsally, do 

 not quite meet in the middle line, and do not quite reach the 

 hind margins ... ... ... ... ... longipalpis, Leic. 



8. White lateral abdominal patches with their upper edges straight; 



hind metatarsi distinctly shorter than the tibiae pendula, sp. n. 



White patches with their upper edges markedly concave ; hind 



metatarsi and tibiae about equal in length ... ... ... 9. 



9. Smaller ; female palpi two-thirds as long as the proboscis 



digitata, sp. n. 

 Larger ; female palpi only half as long as the proboscis pectinata, sp. n. 



1. L. annulipalpis (Theo.). 



Brevirhynchus annulipalpis, Theo., Rec. Ind. Mus. iv, p. 6 (1910). 

 I have not examined the type of this species, and feel some doubt whether it 

 really belongs here, as the type of marking appears to be quite different from
