Horn.] 356 [June 20. 



stria fine, disc with or without faint traces of an oblique dorsal stria. 

 Pygidium finely alutaceous. Prosternura nearly twice as long as wide, 

 striae not more divergent in front, surface with a few punctures. Meso- 

 sternal stria entire, meso- and metasternum coarsely punctuied, the 

 latter less so, suture fine. Tibife slender. Length .03 inch ; .75 mm. 



I am totally unable to appreciate the differences between lateralis, 

 Mars., and strigosus, Lee, and after a careful examination of the species, 

 believe conformis to be merely a somewhat smoother form. 



Occurs in the Southern States. 



A. acaroides, Mars, Mom, 1856, p. 618, pi. 14, No. 43, fig. 18. 



Oval, convex, piceous, shining. Head sparsely punctulate. Thorax 

 finely and moderately densely punctured, basal row of punctures moder- 

 ately coarse, close to the margin and short. Elytra coarsely punctured, 

 punctures strigose at apex, marginal stria moderately deep. Pygidium 

 extremely finely alutaceous. Prosternum longer than wide at middle, 

 stria? divergent in front. Mesosternal stria entire, meso- and metasternum 

 coarsely punctured, suture fine but distinct. Tibiae slender. Length 

 .05 inch ; 1.25 mm. 



I have the type alone before me. Closely allied to strigosus. 



Occurs in the Southern States. 



A. atDHius, Lee, cited by Marseul from New Orleans, is from Cuba. 

 iELETES, n. g. 



The absence of scutellum is the only character separating the species 

 below from Acritus. 



They are as follows : 



Surface smooth, impuuetured. 



Prosternum twice as long as wide politus. 



Prosternum nearly as wide as long brevisternus. 



Surface punctured. Thorax with basal row of punc- 

 tures. 



Basal row of punctures short, arcuate basalis. 



Basal row of punctures straight, long simplex. 



A. politus. Lee. Proc. Acad., 1853, p. 290 ; Mars. Mom, 1856, p. 610, 

 pi. 14, No. 43, fig. 10. 



Oval, convex, brown, shining, impuuetured. Prosternum twice as 

 long as wide. Mesosternum longitudinally sulcate, stria obliterated at 

 middle, suture not evident. Length .03 inch ; slightly less than 1 mm. 



Occurs in the Middle, Southern and Western States. 



A. brevisternus, Mars. Mom, 1856, p. 609, pi. 14, No. 44, fig. 9. 



Oval, convex, brownish, shining, impuuetured. Prosternum scarcely 

 longer than wide. Mesosternum with stria interrupted, surface nearly 

 impunctured, suture indicated by a transverse row of coarse punctures, 

 the punctures finer at the sides and elongate in the middle. Length .035 

 inch ; .8 mm. 



One specimen, the type, is before me. Occurs in Louisiana.
