ELEODES MUTILATA 223 



brown setiform hairs, which are graduated from base to apex; similar 

 setiform hairs form apico-marginal tufts on the other joints, divided at 

 middle, and leave the plantar grooves open ; on the middle tarsi the 

 plantar grooves are open, the joints are fringed beneath with golden 

 brown setiform hairs. 



Female. Stouter, body rather more inflated and broader. 

 Abdomen horizontal, rather evenly and not strongly convex. Plantar 

 grooves open on all of the tarsi; joints with apico-marginal tufts of 

 golden brown setiform hairs. 



Measurements. Length (Types), 28-26 mm.; width, 11 mm. 



Holotype, male, in the collection of the California Academy of 

 Sciences ; paratypes in the Academy's and the author's collection. Three 

 specimens studied. 



Type locality and habitat. Sierra Laguna, Lower California; col- 

 lected by J. R. Slevin on August 15, 1919. 



The form and habitus are exactly alike in mutilata and lucae Lee. It 

 has the appearance of being an edentate and smooth lucae. The anterior 

 femora are entirely mutic. As nothing is known regarding the status 

 of similar forms it is best to consider it a species rather than a race of 

 lucae. 



The following are the genital characters : 



Male. Edeagophore oblong-ovate, moderate in size, about two and 

 a half times longer than wide and feebly arched. 



Basale not strongly convex, less so on the dorsum, with an impressed 

 median groove ; sides parallel, less than moderately and broadly arcuate, 

 apex bilobed, median emargination arcuately rounded at bottom. 



Apicale triangular, apex short and rather obtusely rounded ; sides 

 broadly arcuate, but briefly sinuate at sides of apex ; surface convex 

 with an impressed median groove extending from apex to base ; base 

 sinuate laterally, adapted to the apical lobes of the basale, obtusely lobed 

 at middle. 



Female. Genital segment subtriangulo-parabolic, moderate in size 

 and setose. 



Valvula. Dorsal plate oblong, rather narrow, sides feebly arcuate, 

 with apex rounded; surface feebly concave, finely and very sparsely 

 punctate, each puncture with a very small seta. Apex short, stout, 

 rather broadly rounded at tip, somewhat divergent with that of the 

 opposite valve. Appendage situated at and almost beneath the apical 

 margin of the dorsal plate, very small and not easily seen within the 

 fossa. Fossa moderate in size, adjacent surface of apex with many 

 short hairs. Superior pudendal membrane attaining the middle of the
