coarsely rather closely punctate, last ventral without or with a trace of a thick sub- 

 apical carina. Prosternum sinuate in front and nearly attaining at the sides the an- 

 terior angles of the thorax. Hind tarsi barely as long as half the tibia;. Length, 6-7.5 

 mm., .24-. 28 inch. 



Habitat : Lower California (San Jose del Cabo). 



Mixed with the typical specimens above described are smaller ex- 

 amples having the same general appearance but differing quite con- 

 stantly in being more pointed behind, in lacking the thoracic spot, in 

 the posternum being almost without trace of sinuation in front, and 

 in the better developed carina of the last ventral. It will be noted 

 that these differences are, except the first, precisely those used to dis- 

 tinguish suhbalteata from opinabilis, but whether they are a variety of 

 opiiiabilis or of suhbalteata, or a new species, or whether all three are 

 one, is a question for the future student to answer. The specimens 

 before me were received from Mr. Fuchs and bear the label '^ texana 

 teste Horn ;" there must however be some mistake here, as the speci- 

 mens in the Horn cabinet are not placed with texatia nor does the 

 latter name appear on the list of species from Lower California.

No comment on this species seems necessary. It is closely allied 

 to neglecta, but the tabular characters are, I think, sufiicient to separ- 

 ate it. Length, 5-7.5 mm., .20-. 30 inch. 



Habitat : Eastern United States extending to Texas. 



A. neglecta, sp. nov. 



This name is proposed for a form occurring abundantly in Texas 

 and heretofore considered merely a form of tubulus. The characters 

 given for its separation in the table, viz. — generally smaller size, con- 

 vex nearly unimpressed front, narrower elytral internals, and confluent 

 markings are so constant in the large series at hand that I am con- 

 vinced of its distinctness. I have seen one specimen of tubulus from 

 Texas, differing scarcely at all from the typical eastern form. Length, 

 4.2—5.6 mm., .17-. 23 inch. 



Habitat : Texas. 



A. conoidea, sp. nov. 



Convex, pointed behind, surface dull, clothed with short coarse setiform hairs ; 

 thorax unicolored, elytra with an irregular median yellow stripe formed by the 

 coalescence of the usual spots. Head coarsely closely punctate, the punctures shal- 

 low ; front feebly convex scarcely impressed at middle, vertical carina obsolete, cly-
