130 MEMOIRS ON THE COLEOPTERA 



unable to place anywhere in the series ; these are as follows from the 

 original descriptions: 



H. comis Hald. Shining black above and upon the under surface 

 of the head and prothorax, chestnut brown beneath; antennae, palpi and 

 legs yellow testaceous; head with a small round indentation at the inner 

 base of the antennae; pronotum widest before the middle, contracted 

 behind, with the angles slightly obtuse; basal impressions shallow, some- 

 what rugulose; dorsal impressions distinct; lateral margin testaceous; 

 elytra simply striate, slightly sinuate, the margin rufo-piceous toward 

 tip; interstices rather flat, the third with a faint puncture. Length 8 

 mm.; width 3 mm. Pennsylvania. 



At first LeConte (Cat. Col., Sm. Inst.) thought that this might 

 be the same as spadiceus Dej., but he afterwards concluded that 

 Ophonus mutabilis Hald., was the same as the latter, leaving comis 

 unidentified. I do not know of any late reference to the species. 



H. curtatus Mann. Rather short in form, parallel, black and shining, 

 the palpi short; antennae and legs rufo-ferruginous; prothorax very short 

 and transverse, twice as wide as long, smooth, the sides evenly and 

 moderately rounded; all the angles rounded, the base foveolate at each 

 side, the foveae impunctate; elytra striate, the third interval impunctate. 

 Length 7.5 mm.; width 2.3 mm. Alaska (Kenai Peninsula \Yoskre- 

 sensk Bay). 



The antennae are said to be only half as long as the head and 

 prothorax combined. It is evidently a peculiar species, of unusually 

 small size and may not be truly a Harpalus. 



H. depressicollis Mots. Elongate, subparallel, somewhat depressed, 

 black, the two basal joints of the antennae, the palpi and tarsi testaceous, 

 the labrum and epistoma margined with testaceous, the front with a 

 rufous spot; head rather short, with a transverse impression between the 

 antennae and two minute diverging grooves, which limit at each side a 

 triangular cavity, which is somewhat rugose; prothorax slightly broader 

 than the head, depressed, quadrate, rather broadly margined at the 

 sides and feebly narrowed posteriorly; there is at each side of the base 

 a shallow impression, which is covered, like the rest of the basal region, 

 with a fine close punctuation, which diminishes gradually toward the 

 middle; elytra broader than the prothorax and more than twice as long, 

 opaque, the second stria unipunctate, the under surface and epipleura 

 dullish black. Length (9) 9.0 mm.; width 3.3 mm. California. 



This species evidently belongs to the genus Anisodactylus , for 

 the red spot on the head is frequently observable there but never in 

 Harpalus, and the pronotal sculpture also agrees better with that 

 genus. I however fail to recognize it among my material; it is 

 more slender in form than any true Anisodactylus known to me.
