rounded : strire feebly impressed and scarcely punctate : intervals extremely 

 finely punctate ; underside smooth, scarcely punctate. Length, 2 mm. 



Huachuca Mts., Arizona. 



The specimen described is a male and differs from those in our 

 fauna, having the third joint of antennae shorter than the second, the 

 labrum entire and the form depressed, by the large head, the thorax 

 narrower towards base and the size of the antennal joints. It re- 

 sembles somewhat the figure of L. ccphalicits* from which, however, 

 it differs in having different antennal joints, position of the eyes and 

 apparently more elongate form. The figure of L. lucanoiucs Smith,f 

 resembles the above described insect still more closely, but besides 

 different color of head and prothorax, that species has a shorter 

 prothorax, with the sides slightly sinuate behind, which are in 

 macroccphalus almost straight from about apical fourth to the basal 

 angles. 

 8. Laemophloeus dimidiatus, new species. 



Form convex, color reddish testaceous, legs and base of elytra slightly 

 paler; apical half of elytra, and abdomen piceous or fuscous, outer joints of 

 antenna; fuscous. Head rather coarsely punctate, punctures well separated ; 

 finely, longitudinally impressed at middle ; eyes moderately prominent ; epis- 

 toma trisinuate, epistomal suture deeply impressed ; labrum broadly arcuate 

 at apex ; antennae scarcely reaching the apex of elytra in the male, shorter in 

 the female, third joint longer than second, joints three to eleven equal and 

 elongate in the male, last three joints in the female slightly longer and wider 

 than the preceding joints. Prothorax at apex as wide as the head across the 

 eyes ; sides arcuately narrowing to base, basal angles rectangular, acute ; disk 

 rather coarsely but not densely punctate ; lateral stria well impressed. Scu- 

 tellum transverse, scarcely punctured. Elytra wider than the prothorax at 

 base ; sides feebly arcuate ; apices rounded ; disk with seven, somewhat coarsely 

 punctate stria;, intervals with a single row of punctures ; sutural intervals 

 rather confusedly punctate ; alternate intervals wider than the others. Under- 

 side rather coarsely punctate ; abdomen more finely and sparsely punctate. 

 Length, 2.75 mm. 



Huachuca Mts., Arizona. 



This species is best placed near L. adustus Lee, from which it 

 dift'ers in being more elongate, sides of prothorax less arcuate and 

 slightly narrower, more elongate antennal joints and disk of elytra 

 with more striae.
