NOTES ON GENERIC CHARACTERS IN THE LYCOSID^. 



BY RALPH V. CHAMBERLIN, ITHACA, N. Y. 



(Continued from page 148.) 



In Lycosa there is in most cases present a small, apically more or less 

 rounded flap or lobe at and pressing against the base or origin of the 

 embolus. This lobe, which may be spoken of as \\\t palea, is often small or 

 but weakly developed ; but in L. piilchra it is very long and conspicuous. 

 Here it embraces and supports the embolus along much of its length, 

 being at the same time shifted ectad from its usual position. This special 

 development of the supporting palea in L. pulchra is associated with the 

 peculiar position of the embolus, which, instead of curving back to rest 

 along the lectus in the usual manner, here arches forv/ard and outward 

 (i. e., ventrad) free from the bulb, only its apical part, which turns forward 

 and rests obliquely across the auricula, being at all in contact with the 

 lectus. The unusual size of the palea is evidently necessitated by the 

 otherwise unsupported condition of the proximal portion of the embolus. 



Above and ectad of the origin of the embolus is a variously 

 complicated lobe, which was first unhappily termed the $peri?iaphorum by 

 Menge, under the false impression that its function was that of a sperm
