Baring 469 



Anacentrus subcrenatus n. sp. — A little larger and stouter than apertus, 

 similarly subdepressed and shining, black throughout, the sparse and 

 minute hair-like squamules similar; beak similar, the antennae slightly 

 longer, the basal funicular joint more notably elongate; prothorax 

 similar but with the punctures stronger, notably coarser and more rugose 

 toward the sides; elytra nearly similar but with the somewhat coarser 

 grooves more coarsely and subcrenately punctate, the punctures of the 

 interstitial series small but stronger than in apertus. Length (9) 3-5 

 mm.; width 1.4 mm. Texas (El Paso), — Dunn. 



This species is not as large as nasutus, and the elytral grooves are 

 less coarse and more crenately punctate; the beak is relatively a 

 little longer and more arcuate and the sculpture toward the sides 

 of the pronotum coarser, dense and more rugose. 



Anacentrus franciscus n. sp. — Body nearly as in nasutus but much 

 smaller, similar in color and in general features of sculpture and vestiture; 

 beak in the female nearly similar but shorter, not longer than the pro- 

 thorax and more arcuate; prothorax similar but with the apex still 

 more abruptly tubulate, the punctures finer and more numerous, a little 

 coarser and moderately close at the sides; elytra almost similar but 

 shorter, only three-fourths longer than the prothorax, the small punc- 

 tures along the bottom of the striae more distinct and sharply defined 

 but not at all crenate; interstitial serial punctures still smaller. Length 

 (9) 34 mm.; width 1.3 mm. California (San Francisco). A single 

 example, taken by the writer. 



The four forms nasutus, apertus, subcrenatus and franciscus, 

 form a compact small group of the genus and are undeniably closely 

 interallied, so that they might appropriately be considered, per- 

 haps, as subspecifically related to one another. Nasutus is the 

 largest, being somewhat over 4 mm. in average length, and is from 

 southern California — described from Tejon — and in my collection 

 is represented by a series of five specimens from Los Angeles Co. 



Anacentrus angustus n. sp. — Form narrow, very elongate and some- 

 what depressed, the upper profile of the pronotum only just visibly 

 arcuate, the color dark red-brown throughout, the lustre moderately 

 shining; squamules of the upper surface small, slender and yellowish, 

 indistinct on the pronotum except along the sides, where they are sparse 

 and very minute, forming single lines on the strial inteVvals, minute and 

 sparse beneath; beak in the female rather short, scarcely as long as the 

 prothorax, cylindric, evenly and moderately arcuate, finely punctulate, 

 the antennae near four-sevenths, the first joint of the club much more 

 than half the mass; prothorax distinctly longer than wide, the sides 

 parallel and straight, gradually and moderately rounding before the 

 middle, the tubulate apex two-thirds as wide as the base; punctures 

 moderate and well separated, coarser and rugulosely confluent at the
