t08 Goleopterological Notice.^, VI. 



rounded, the tempora becoming parallel; eyes moderatelj^ large and prominent; 

 disk rather finely but strongly, closely punctate, with a very well defined 

 entire and somewhat narrow impunctate line; antennte slender, as long as the 

 head and prothorax, feebly incrassate, the tenth joint fully as long as wide. 

 Proihorax scarcely' more than tliree-fourths as Avide as the head, somewhat 

 longer than wide, rounded at the sides anteriorly, finely, deeply, very densely 

 punctate. Elytra somewhat more than three-fourths longer than wide, twice 

 as wide as the prothorax, the sides parallel, evenly and feebly arcuate, the 

 apex not very broadly rounded ; scutellar impression broad and distinct, the 

 omoplates almost obsolete; punctures strong and close, moderately coarse, very 

 much finer toward apex. Abdomen alutaceous, minutely, extremely densely 

 punctate and finely reticulate, more shining and distinctly punctate toward 

 base. Lcg.s moderately short, slender, the femora minutely aud densely punc- 

 tate. Length 2.9 mm. ; width 0.8-0.9 mm. 



California (Mendocino, Humboldt, Lake and Sonoma Cos.). 



It is possible that there maj- be some closely- allied species in- 

 termingled in the large series before me, but they cannot be ad- 

 vantageously^ separated at present. This species is closely allied 

 to puncfidatus and is similar in the male sexual characters, but it 

 is somewhat more slender, with less elongate elytra, more finel3' 

 and much more densel}" punctate head and prothorax, the latter 

 relativel}' narrower, and is never black, while of the numerous 

 specimens of j^unctulatus which I have taken, none are pale and 

 the two forms are never found in the same locality. 



The elytra are impressed along the sutural margin toward apex, 

 especially in the male. 



A single female from Tahichipi Pass is associated with mer- 

 curiaJis for the present, but it almost certainly represents a dis- 

 tinct and decidedl}' stouter species.

Rufo-ferruginous, feeblv shining, strongly', very densely punc- 

 tate throughout, the punctures of the el3'tra not coarse ; el3'tra 

 with a transverse blackish fascia at the middle and another near 

 the apex, enclosing a large pale spot at apical third, the macula- 

 tion always more or less nubilate and frequently obsolete. 

 Length 2.2-2.7 mm. ; width 0.7-0.95 mm. 



Entire Tnited States east of the Rocky Mountains, from Idaho 

 (Co?ur d'Alenej to New York, Texas and Mississippi. This 

 species is so common and well known that further description 

 would be superfluous in this imperfect revision.
