no. 3649 LEPTOFERONIA — HACKER 35 



Color of body. — Light rufous. 



Head. — Head large in proportion to body; mandibles large, but 

 not especially elongate or toothed; clypeus and labrum normal; 

 frontal impressions fairly deep; occipital prominence normally large; 

 groove above eye prominent; posterior pair of setiferous punctures 

 farther removed from groove above eye than in other Leptqferonia; 

 pigmented eyes very small, about as long as second antennal segment; 

 disc with sparse, fine punctures, faintly microstrigulose. 



Pronotum. — Narrow, widest just behind prominent anterior angles; 

 posterior pair of setiferous punctures at rectangular or acute angles; 

 transverse basal impression entirely absent; area between shallow 

 inner longitudinal impression and lateral margin nearly flat; outer 

 impression absent; disc flattened along midline, which is incised 

 deeply; microsculpture same as head. 



Elytron. — Humerus dentate; scutellar stria present; scutellar 

 puncture absent; setiferous punctures on eighth stria consisting of 

 six in anterior series, no intermediate, four or five in posterior series; 

 only one seta on seventh stria; microreticulate. 



Ventral surface. — Mesepisternum with coarse punctures; metepi- 

 sternum and sides of metasternum with sparser punctures; proepi- 

 sternum and sides of prosternum with finer, sparser punctures. 



Legs. — Hind trochanter tapering to point, about half the length 

 of hind femur, reaching nearly to setiferous puncture on femur in 

 males; hind femur obtusely angulate along posterior margin in males; 

 no setae on ventrolateral margins of last article of tarsus. 



Sixth abdominal sternum of male (fig. 18). — Unmodified. 



Aedeagus (fig. 18). — Right paramere short. Median lobe flattened; 

 tip evenly rounded; no lightly sclerotized strip; small lobe on right 

 side of ventral surface. Internal sac without sclerotized tooth. 



Length of body. — 9.0 to 12.0 mm. 



Type. — Not seen. 



Type-locality. — "Sylvania" [Camp Meeker, Sonoma County], 

 Calif. 



Specimens examined. — 22. 



Distribution (fig. 38). — Most known specimens are from the 

 Glen Ellen-St. Helena area with individual specimens from as far 

 north as five miles west of Comptche, Mendocino County, Calif. 



Remarks. — The three species caligans, beyeri, and jalli resemble 

 each other in having large heads and mandibles and small eyes. 

 They differ in a number of other characteristics, however; I doubt 

 that they are closely related.
