Arizona. 

 . The single specimen described is narrower than the females of 

 biguttatiis and fasciatus, has a different form of prothorax, the front 

 of head broadly depressed at middle and the pale spot on each 

 elytron is slightly postmedian. 



6. Laemophloeus flavosignatus, new species. 



Slightly depressed, black, shining, underside, legs and antennae piceous ; 

 •elytra with a yellow, irregularly rounded spot at middle. Head subtriangular ; 

 eye§ moderate, not touching the apical margin of thorax ; epistoma truncate, 

 separated from the front by a deeply impressed and feebly arcuate line ; 

 labrum truncate in front ; surface moderately coarsely, but not densely punc- 

 tate, except at middle, where a narrow, longitudinal space is free from punc- 

 tures ; antennje short, third joint longer than second ; fourth to tenth sub- 

 equal ; eleventh, as usual, slightly more elongate. Prothorax as wide as the 

 head ; sides moderately arcuate in front, narrower behind and feebly undulate 

 before the hind angles ; the latter acute and slightly in advance of the basal 

 margin ; surface moderately coarsely but not densely punctate, lateral strise 

 distinct but not very deeply impressed. Scutellum triangular ; sparsely punc- 

 tate. Elytra slightly wider than the prothorax in its widest part ; sides feebly 

 arcuate ; apices conjointly, broadly rounded ; surface with sutural and two 

 discal stripe on each side ; intervals irregularly biseriately punctate ; lateral 

 carina rather strong. Abdomen sparsely punctate. Length, 2.75 mm. 



Arizona. 



Differs from our similarly marked North American species by the 

 truncate labrum and epistoma slightly more convex, the more grace- 

 ful form and the last three joints of antennas not enlarged in the 

 single specimen, which I take to be a female. The pale spot on each 

 elytron is situated at middle and not before or behind middle as in our 

 other species. 



7. Laemophloeus macrocephalus, new species. 



Form depressed, elongate, shining, surface glabrous, color reddish testa- 

 ceous, elytra paler. Head large, sparsely and rather finely punctate ; epistoma 

 broadly emarginate, epistomal suture deeply impressed ; labrum truncate ; eyes 

 moderately prominent, situated at middle between the antennal insertion and 

 the apex of thorax ; antennje long, reaching nearly to the apex of elytra, joints 

 elongated, third slightly longer than second, sixth to tenth nearly equal in 

 size but slightly longer and feebly wider than the two preceding joints. Pro- 

 therax quadrate, as ^ide at apex as the head ; sides obliquely narrowing to the 

 basal angles ; the latter acute ; surface finely and rather sparsely punctate ; 

 lateral stria distinct. Scutellum triangular, smooth. Elytra slightly wider 

 than the thorax at base ; humeri rounded ; sides feebly arcuate ; apices broadly
