84 JouRNAf, New York Entomological Societv. [Voi. xv. 



Numerous examples taken by Professor Snow at San Bernardino 

 Ranch, Douglas, Arizona, where they were found breeding in stems 

 of yucca. Rather larger than any other species of our fauna ; by the 

 latest table it would stand nQdiX perpkxus. 



Liopus decorus, new species. 



Not very robust, densely clothed with short prostrate cinereous hair, maculate 

 with black as follows : prothorax with two round anterior spots and the median line 

 posteriorly, these usually more or less coalescent and diffuse ; elytra with a rather large 

 lateral spot just before the middle, and at the posterior third a common more or less 

 evidently angulate fascia which is more or less irregular and is usually broken up 

 externally into small black spots ; there are also small black spots scattered over the 

 surface, those at the middle sometimes imperfectly continuing the median lateral spot 

 to the suture. Punctuation well developed throughout, erect tufts of setae entirely 

 wanting. Lateral spine of prothorax at the posterior third or fourth. Length 5-6 

 mm., width 1.8-2.3 mm. 



Williams, Arizona. July. Collected by Schwarz and Barber and 

 by the writer. 



A very pretty species, which Mr. Schwarz has referred to centralis 

 Lee. The latter, however, is more robust, somewhat differently 

 marked, the prothoracic spine is said to be just behind the middle, 

 and the elytra bear small tufts of black scales. 



Ataxia sulcata, new species. 



Dark brown, nearly parallel, sparsely pubescent with brownish ochreous hairs, 

 with a few white hairs intermixed. Head finely densely punctulate, with scattered 

 coarser punctures. Antennae ( 9 ) scarcely as long as the body, feebly annulate 

 externally. Prothorax about as long as wide, base evidently wider than the apex, 

 sides broadly arcuate and rather feebly tuberculate at middle, base with a marginal 

 impressed line, disk closely punctate, median line plainly carinate anteriotjy in some 

 examples, scarcely so in others. Elytra nearly parallel, broadly rounded and scarcely 

 truncate at apex, each with five or six discal sulci which are gradually shallower 

 externally ; sides not sulcate ; punctures arranged in nearly regular rows, each having 

 a short semi-erect hair; pubescence otherwise very short and recumbent. Length 

 12-15 niiii. 



Florida (Key Largo). ^^ 



Two examples, both apparently females, received from Mr. Beyer. 

 Distinguishable at once from our other species by the sulcate elytra 

 and very sparse pubescence. 



Ataxia setulosa new species. 



Rather slender, parallel, very densely clothed with recumbent ochreous hair, 

 with the usual fine suberect setae arising from the elytral punctures darker in color ; 

 elytra also with numerous setiform fascicules each consisting of from three to six
