looks distinctly grayish-white, while the pubescence of subcostatus 

 appears to be dark brownish. 



It is possible that this form is the true cyanipcnnis of Klug, 

 which is recently placed as a synonym of thoracicus. 



Aulicus femoralis new species. 



Head, first three joints of antennse, prothorax at sides, an elongate 

 humeral spot, an oblique submedian spot, side margins from the humeral to 

 the submedian spot, underside, except fifth ventral segment which is black, 

 and femora at basal half more or less red ; disk of prothorax black ; elytra 

 blue except the spots indicated above. Head rather coarsely and subrugosely 

 punctate, the punctures sparser at middle. Prothorax slightly wider than 

 long, basally strongly constricted and less strongly near apex ; surface mod- 

 erately coarsely and rather evenly punctate. Elytra not quite three times as 

 long as the prothorax, sides nearly parallel to about basal fifth, thence gradu- 

 ally widening towards middle, from here to apex arcuately narrowing to apex, 

 apices separately rounded ; surface rather coarsely and confluently punctate, 

 the punctures finer in the pale markings ; vestitures as well as that of pro- 

 thorax moderately long and whitish. Ventral segments rather sparsely 

 punctate ; fifth segment broadly subtriangularly emarginate ; sixth segment 

 broadly rounded and with a very deep median impression. Legs clothed with 

 moderately long hairs. Length 6 mm. 



Nogales, Arizona (F. W. Nunnenmacher). 



By its coloration this species is related to monticola but is smaller 

 and a little more robust with prothoracic punctures more numerous 

 and the submedian fascia at middle rather obliquely bent down towards 

 apex. It is perhaps a color variation of A, nero which I do not know, 

 the dififerent descriptions of that species describe the head, prothorax 

 and legs black or bluish black. 



Hydnocera fuchsi Schaeffer. 



Hydnocera fuchsi Schaef., Journ. N. Y. Ent. Soc, Vol. XVI, p. 132. 

 Hydnocera nunnenmacheri Schaef., /. c, p. 133. 



Although the type of nunnenmacheri is a much smaller and rela- 

 tively narrower insect I am convinced that it is the same as fuchsi. 

 Besides being smaller and of narrower form there is nothing to 

 separate the two. 



Cregya peninsularis new species. 



Form, size and coloration of leucophcca {vetusta) from which it ditfers 

 in having a slightly shorter prothorax with the surface at sides less irregular 

 but with the median and two oblique basal impressions very distinct and deep.
