inflexed portion of the base on each side of the* scutellum. The 

 markings, as shown by omogera, discoidea, etc., differ so greatly that 

 very little stress can be laid on these differences. 



Hydnocera simulans, new species. 



Form of scabra black ; head and thorax slightly aeneous ; elytra bluish black, 

 with a subtriangular basal and a transverse submedian spot yellow ; legs yellow, ex- 

 cept posterior and intermediate femora and tarsi, which are more or less infuscate. 

 Head, including the eyes, nearly as wide as the elytra at base, but narrower than the 

 thorax; densely pubescent, obscuring the surface sculpture. Thorax deeply con- 

 stricted at apex ; sides below the constriction strongly dilated and then nearly parallel 

 to base ; sculpture obscured by the dense pale pubescence. Elytra normally covering 

 the abdomen ; scarcely narrowing towards apex ; apices separately rounded, but the 

 outer margin obliquely rounded and not serrate ; punctuation very coarse and close, 

 apical portion below the submedian spot cribrately punctate ; pubescence much 

 sparser than on head and thorax, slightly denser and directed outwardly on the sub- 

 median, pale spot. Body below sparsely pubescent. Length 4 mm. 



Huachuca Mts. , Arizona. 



I have placed with this species two smaller specimens which have 

 no basal spot, but only the postmedian pale spot, otherwise they do 

 not offer any differences. These seem to be the same as the one men- 

 tioned by Gorham in the " Biologia " on page 345 under 14 (c) but 

 not described. 



This species is closely allied to cribripennis Fall, which has slightly 

 shorter elytra, apices broadly and more evenly rounded and serrate 

 and the submedian spot a little nearer to apex. It seems also to be 

 allied to rudis Gorh., which is said to have the sides of thorax not 

 much dilated and head and thorax clothed with black, upright pile, 

 besides the ashy, depressed hairs. 



Hydnocera nunnenmacheri, new species. 



Blue-black; head and thorax slightly greenish ; antenna and tarsi only paler ; 

 elytra with a median fascia of dense, pale hairs. Head densely punctate, pubescence 

 moderate, recumbent, pale, with some longer darker hairs intermixed. Thorax nar- 

 rower than the head ; apical constriction strong ; sides strongly dilated ; basal im- 

 pressed line strong ; surface densely punctate at sides, very slightly sparser on disk ; 

 pubescence moderate, pale, recumbent, intermixed with longer dark hairs. 

 about as wide as the head, rather short ; sides parallel ; apices separately rounded 

 and feeebly serrate ; surface somewhat coarsely but not densely punctate ; intervals 

 between the punctures rugose, feebly at base, but more strongly below the median 

 fascia of pale hairs ; surface sparsely pubescent with pale, short hairs, intermixed 

 with longer darker hairs, the pale hairs more numerous and denser in a transverse 

 space at middle, forming a fascia. Body beneath sparsely pubescent ; abdomen slightly 

 longer than the elytra. Length 4 mm.
