II. edwardsii, piceous with slight seneous tinge. Head coarsely and rather densely punctured. Thorax 

 broader than long, moderately convex, rather finely punctured and more densely at the sides; apex sub-truncate, base 

 feebly rounded at middle, sides rounded in front, slightly sinuate and feebly narrower at base, margin acute, not 

 broad, apical angles obtuse, hind angles rectangular. Propleurse coarsely and irregularly wrinkled and punctured, 

 rnesosternum coarsely punotured. Elytra oblong; feebly broader behind middle, sides feebly rounded; surface mod- 

 erately convex, rather deeply striate, stria; not punctured, interspaces feebly convex and sparsely punctulate. Body 

 beneath coarsely but not sparsely punctured, abdomen more densely punctured and at the sides wrinkled. 



Length .03 Inch. 



Resembles a large specimen of calif omiens, from which it may readily be distinguished 

 by the form of the thorax and the sculpture of the propleurse. The elytra arc also much 

 more deeply striate. The antenna? are broken, but they appear to be as in califomicm. 



For a single female specimen T am indebted to Mr. II. Edwards, of San Francisco, to 

 whom I with pleasure; dedicate; it. 



Collected in Oregon. 



H. pernitens, Lec.,Proc. A.cad, [861, p. 858. 



Thorax one-half broader than long, apex and bast; of equal width, the former truncate, 

 the latter feebly rounded ; sides rounded, very distinctly margined, margin slightly re 

 flexed. Antennae slender, outer joints very feebly decreasing, last joint elongate, some- 

 what longer than the tenth. Elytra rather broadly oval, finely striate, surface smooth and 

 polished. Propleurse finely wrinkled. 



Length .40 inch.

It. lictus, Leo., Proc. Acad., Pacif. R. R. Hop. IX, App. 1, p. 51. 



Thorax as in califomiom, but rather more transverse. Margin broad, slightly reflexed 

 and broader than the hind angles. Antenna) with sub-equal joints, last joint rounded anil 

 smaller than the tenth, Propleuree finely rugose. Elytra less rounded than in pernitens, 

 more deeply striate, and with the interstices feebly convex. Surface smooth, shining, cu- 

 preous metallic.

II. rugioollis, Lee, New Species, p. 188. 



With this species begins our series of apterous llelops. The very short robust an- 

 tennae serve; to distinguish this specie's from those to which it has most resemblance in 

 form and other characters. The antenna' axe not longer than (lie head and thorax, ro- 

 bust, outer joints compressed, last three shorter; joints nine and ten sub-triangular, 

 broader than long, last joint oval and shorter. The head and thorax arc rather densely 

 aciculatcly punctured, and reddish brown. Thorax slightly broader than le>no-, apex trun-
