444 GEOLOGICAL SURVEY OF THE TEEEITOEIES. 



From Northern Arizona. Obtained from the collection of Dr. Palmer, 

 in the Agricnltnral Department, at "Washington. 



This is a very interesting species, as it is the first of this genus, as at 

 i:>reseut restricted, which has been found in the TJuited States. I have 

 therefore made my description very full, including some generic char- 

 acters. It is remarkable for the length of its wings and its dark, som- 

 ber color. 



Figured by Professor Glover. PI. 1, Fig. 9. 



L. occidentalism nov. sp. 



Female. — Testaceous, with a row of black spots along the middle of 

 the elytra. Closely allied to L. fuUginosa, but smaller, and rather more 

 sleuder in its proportions. 



Occiput not ascending, convex, transverse ; tubercle compressed on the 

 sides, slightly sulcate. First joint of the antenna? convex in front, with 

 a slight tubercle at the base. Pronotum longerthan broad, somewhat 

 carinated ; lateral carinas rounded on the anterior lobes, angled on the 

 posterior, slightly converging near the middle ; a faint medium line visi- 

 ble; margins as in fuUginosa. Elytra about twice the length of the 

 body ; narrow, equal width throughout ; round at the apex. Tlie sternal 

 spines and lobes as in fuliginosa. Middle femora longer than the ante- 

 rior, slender sub-cylindrical; the anterior femora have from three to five 

 small spines on the inner carina; middle and posterior femora have a 

 few minute distant spines on each carina. Anterior tibioe with one row 

 of three spines in front; middle with two rows above, four or five in 

 the internal, and tv/o in the external. 



Color, (dried, but does not appear to have been immersed in alcohol.) — 

 Testaceous. Face pale brownish-yellow; an irregular black stripe 

 reaches from the eyes to the posterior margin of the pronotum, running 

 along the side of the latter, immediately below the lateral carina. The 

 pronotum brownish above, paler below the stripe on the side. Elytra 

 testaceous, the middle field marked with a row of black spots, which 

 form a kind of serrature along the externo-median nerve, the inter- 

 spaces whitish; the upper field somewhat regularly variegated with 

 pale, brownish, rhomboid spots ; lower field pale, with clusters of dark 

 points. The wings fawn-colored ; nerves and nervules of the front mar- 

 gin black, prominent; rest mostly the color of the wings, and less prom- 

 inent. Spines tipped with piceous ; soles of the tarsi fuscous. Auten- 

 use wanting in my specimen. 



Dimensions. — Length of body, .95 inch; elytra, 1.80 inches; poste- 

 rior femora, 1.14 inches; posterior tibiee, 1.13 inches; ovipositor, .97 

 inch. 



California. Eeceived from Mr. Taylor, of San Francisco, as a Califor- 

 nia species. Pi. II, Fig. 16. 



CONOCEPHALINI. 



CojnopJioya mucronata, Thos., (Canadian Ent., 1872, p-.) 



Cone of the vertex smooth on the margins, mucronate. Mesosternu 

 bidentate. Green ; labrum, clypeus, and under side of the cone yellow. 

 Male and female. — Cone of the vertex standing obliquely forward, apex 

 mucronate ; the minute spine slightly deiiexed, especially in the female; 

 sides parallel from the base a little above the first joint of the antennse, 

 where they are slightly angulate ; not serrated or granulate ; front side 

 has, near the base, a prominent tubercle; there is also a tubercle below 

 this between the antennae. Face oblique, smooth; occiput smooth;
