Abdominal sexual characters. Male: sixth ventral deeply emar- 

 ginate, seventh rather broad, strongly produced, passing the sixth by 

 nearly twice the length of the latter, gradually somewhat narrowed 

 apically, the tip notched or narrowly emarginate, medially grooved or 

 impressed and appendiculate each side near the base of the emargina- 

 tion; last dorsal not produced, broadly rounded at tip. 



California. Marin Co., numerous specimens from Muir 

 Woods, IV-23; Lagunitas, IV-25, and "Marin Co," (type cT), 

 all sent by Dr. Blaisdell. 



Var. longipennis var. nov. 



Two examples (cf, 9) from Eureka, Cal. (H. S. Barber), are 

 provisionally separated as a variety of the preceding. In the male the 

 elytra seem slightly longer than in the typical form, or any other form 

 known to me; the antennee are a little paler basally, the seventh 

 ventral of the male narrower, not medially impressed beneath at tip, 

 the appendix therefore not double, but continuous from side to side. 



Malthodes appendiculatus sp. nov. 



Fuscous, thorax yellow. Antennae (cf) attaining the tips of the 

 wings, fuscous, basal joints paler; third joint slightly or scarcely 

 longer than the second, fourth evidently longer, intermediate joints 

 four times as long as wide. Head distinctly wider than the thorax, 

 eyes rather large, separated anteriorly by a distance less than twice 

 their width as viewed from the front. Thorax moderately transverse, 

 sides just perceptibly converging posteriorly, margin fine, scarcely 

 thickened at front angles. Length 33^2 ™ii^- to tip of wings. 



Abdominal sexual characters. Male: sixth ventral deeply broadly 

 emarginate; seventh rather narrow, passing the sixth by nearly twice 

 the length of the latter, gradually narrowed for three-fourths its length, 

 then widening, ascending and forkfed at tip, each fork appendiculate 

 beneath or emarginate at tip as viewed in profile; last dorsal not 

 produced, broadly rounded at apex. 



California. " Mts. near Claremont" (Baker); Pasadena. 

 A single male from each locality, the first named being the 



type. 



This species is rather closely allied to mollis, but differs 

 appreciably in the seventh abdominal segment of the male, 

 which is here narrower, curved upward at its extremity, the 

 forks more divergent. The eyes are a little more prominent, 

 the thorax feebly narrowed posteriorly, and there are some 

 other slight difTerences which may however be constant. The 

 genital appendages also appear to be different, but these are 

 not very clearly visible in mollis. In appendiculatus there is a 

 long curved central ligula narrower than the seventh ventral,
