back of eyes, with a broad neck, coarsely, densely punctate, opaque; an- 

 tennse moderately stout and extending slightly beyond middle of body. 

 Prothorax campanulate, as broad as long, three fourths as broad as base 

 of elytra, base twice as broad as apex, transverse basal impressions shal- 

 low, posterior angles short, narrow and extending directly outwards. 

 Sides not dilated in front of middle, the disc closely, coarsely punctate and 

 opaque. Scutellum rather finely punctate. Elytra twice as long as broad, 

 humeral angles rounded and not very prominent, sides a bit arcuate and 

 slightly convergent to apex, apices obliquely truncate, disc distinctly and 

 moderately punctate. Length 8 mm., breadth 3 mm. 



Type, a unique in my collection, captured at Havilah, Cal., June 

 19, 1905, by Mr. Fordyce Grinnell. 



This very distinctly marked Leptura would come in our tables 

 perhaps just before L. sexpilota Lee. The prothorax is of about 

 the same type as in that species though the insect is as a whole 

 somewhat larger, generally more robust and with an entirely dif- 

 ferent color pattern not only from that but from any having a 

 similar shaped prothorax. Some few of our Lepturas have the 

 humeri often with triangular patches of red as for instance an 

 occasional L. canadensis Fab., a male of L. Icetifica Lee, and so 

 forth, but these all differ very greatly from this otherwise. The 

 species is evidently extremely local or else very rare as this is the 

 only specimen that I have seen. 



Leptura amabilis Lee. 



This insect as shown by the type which I have recently critically 

 examined is nothing more than one of the darker phases of L. 

 tribalteata Lee. with the yellow bars reduced almost to spots. It 

 is often found in the more northern parts of the range of the 

 species. The name amabilis has priority over tribalteata. L. 

 coquilletti Linnell is the extreme phase at the other end of the 

 area of distribution and extreme in its color pattern as well. In- 

 termediates have been seen which link all three together. 



Leptura hirtella Lee. 



This is merely the male of L. tibialis Lee, the latter name hav- 

 ing priority by many years.
