Prothorax widest at slightly more than one-third its length from the apex 

 where it is as wide as long, and slightly wider and longer than the head; 

 sides strongly convergent and feebly arcuate anteriorly, very feebly convergent 

 and nearly straight posteriorly, base evenly and feebly arcuate throughout, 

 very slightly narrower than the disk and nearly three times as wide 

 as the apex; basal angles slightly obtuse and distinctly rounded; disk 

 moderately convex, very minutely, evenly and densely punctate; in the 

 middle near the base there is a very feeble transverse impression. Elytra 

 at base scarcely one-fifth wider than the pronotum; sides parallel and very 

 feebly arcuate, strongly convergent near the apices; together as wide as long 

 and distinctly longer than the prothorax, slightly incurvate at apex and 

 trisinuate; disk very feebly impressed on the suture toward the scutellum, 

 rather depressed, extremely minutely and densely punctate; punctures 

 scarcely larger than those of the pronotum and not apparently denser toward 

 the base. Abdomen at base nearly three-fourths as wide as the elytra and 

 about four-fifths as wide as at the apex of the fourth segment; three basal 

 segments very deeply and transversely impressed at base; punctures through- 

 out very minute and dense, without trace of coarse punctuation at the bases 

 of the three first segments, the middle carina? being almost obsolete; under 

 side slightly alutaceous and very minutely punctate. Legs slender; first 

 joint of the posterior tarsi as long as the next two together ; claws very 

 long and slender, much longer than the basal joint of the posterior tarsus, 

 Length 3.2 mm. 



California (Gilroy Springs, Sta. Clara Co., 1). 



The first four joints of the anterior tarsus are seen to be 

 equal in length and all clear and distinct, no two of them 

 being in the least anchylosed. The species is remarkably 

 distinct from the four preceding, both in form and in punc- 

 tuation; it is also remarkable for the slight narrowing of the 

 abdomen toward base. 



PONTOMALOTA, n. gen. (Aleocharini). 



Head slightly deflexed, not narrowed toward base; labrum strongly trans- 

 verse, very slightly sinuate anteriorly; mandibles simple; mentum trape- 

 zoidal, large, truncate anteriorly ; ligula short, having at tip two small 

 approximate tubercles. Outer lobe of the maxilla? consisting of two lunate 

 members, the inner corneous, the outer membranous; inner lobe having an 

 internal membranous appendage which is finely ciliate within, the remain- 

 der of the lobe being slender and arcuately toothed at tip, the inner edge 

 being finely spinose; maxillary palpi robust, first joint short, second very 

 slightly shorter than the third, the latter feebly swollen, fourth thin, 

 subulate, affixed obliquely, bulbous at base, and received far within the
