BEMBIDIIN^E 207 



glimpsible; anterior fovea at three-sevenths. Length 2.33 mm.; 

 width 0.83 mm. Texas (Galveston). Two examples. 



luridicollis n. sp. 



Form oblong, somewhat smaller and relatively stouter than in the pre- 

 ceding, shining, similar in color and ground sculpture, but with the 

 head slightly infuscate and the elytra piceous-black; head nearly 

 similar, relatively larger than in omissus, the eyes moderate, rather 

 prominent; antennae piceo-testaceous, flavate basally, shorter than 

 in the preceding, barely two-thirds as long as the elytra, the fifth 

 joint distinctly less than twice as long as wide; prothorax almost 

 exactly as in luridicollis and fully as wide at base as at apex, but 

 with the sides sinuate at a greater distance from the base, becoming 

 parallel in basal fifth or sixth, the angles right and very sharp; elytra 

 scarcely one-half longer than wide, two-fifths wider than the pro- 

 thorax, parallel, with feebly arcuate sides, the humeri even more 

 narrowly rounded than in the preceding species; apex broadly, ob- 

 tusely rounded; striation and foveae as in the preceding. Length 

 2.2 mm.; width 0.78 mm. Mississippi (Pass Christian). 



torrescans n. sp. 



8 Body stout, subparallel, rather convex and shining, the head dis- 

 tinctly, the pronotum very obsoletely, micro-reticulate, the trans- 

 verse reticulation of the elytra finer, closer and more strigiliform 

 than in the preceding-section; color bright rufous, the head deeply 

 infumate, the elytra piceous, each with a large elongate irregular 

 external flavate spot in basal half and a smaller one near apical 

 fourth; under surface rufous, the abdomen black, the legs rufous; 

 head three-fourths as wide as the prothorax, with moderately large 

 and rather prominent eyes, the sulci feeble and remote; antennae 

 fuscous, paler basally, three-fourths as long as the elytra, the' fifth 

 joint fully twice as long as wide; prothorax one-half wider than long, 

 about equally wide at base and apex, the sides strongly, subevenly 

 rounded to a basal parallel part of about a sixth or seventh the total 

 length; angles right, very sharp and more reflexed than in the pre- 

 ceding section, but with the puncture on the edge similarly in ad- 

 vance of the angle; subbasal groove fine, impressed, being a chain of 

 irregular punctures, the basal surface flat; elytra four-sevenths longer 

 than wide, two-fifths wider than the prothorax, parallel, with feebly 

 arcuate sides and moderately distinct humeral angle, evenly para- 

 bolic in apical third; first stria rather strong, the second finer and 

 beyond with barely any trace of striation; anterior fovea barely 

 visibly in front of the middle. Length 2.42.6 mm.; width 0.80.9 

 mm. Texas (Galveston). [Tachys occultator Hayw. nee Csy.]. 



pugnax n. sp. 



Body stout, subparallel, rather convex., shining, similar to pugnax in the 

 minute ground-sculpture and general form, but with relatively much 

 smaller prothorax; color of the head piceous, of the prothorax bright 

 rufous, of the elytra castaneous, with the entire sides broadly and 

 nubilously flavate, most broadly so in basal half; under surface 

 rufous, the abdomen nearly black, the legs flavate; head four-fifths 

 as wide as the prothorax, the eyes rather more prominent than in
