J 42 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. 



Color, piceous black; pronotum and elytra testaceous-brown, the anterior 

 disk of pronotum darker and embolium paler; membrane brown with a 

 transverse row of pale marks at apex of cuneus. 



Described from four males taken by me on a small 

 (cedar?) tree at Ward, Colorado, July 1, 1903, at an alti- 

 tude of 9,300 feet. With these were numerous young, so 

 apparently the males were reaching maturity before the 

 females and may perish much earlier which would account 

 for the scarcity of males in all species of this genus as rep- 

 resented in collections. 



Holotype, male, in collection of the author, paratypes in 

 his collection and in that of the California Academy of 

 Sciences. 



Type locality, Ward, Colo. 



My notes on the Provancher collection indicate that the 

 type of Tetraphleps canadensis Provancher, was in poor 

 condition, leading me to place it in genus Lyctocoris but a 

 study of these allied species now convinces me that it might 

 have been rightly placed after all. It should not be difficult 

 to procure additional specimens from pines about Cap 

 Rouge, Quebec, which would soon settle the matter. 



7. Tetraphleps lepidus, new species 



Smaller and narrower than latipennis with more slender 

 antennae, seg. II being broadly pale in middle, the pronotum 

 entirely black and ostiolar canal distinctly curved apically. 

 Length 2> l / 2 mm. 



Female: Head as long as half the posterior width of pronotum, rounded 

 at apex, the clypeus slightly exceeding the cheeks, base of vertex polished. 

 Seg. I of antennas distinctly shorter than apex of head ; II equal to median 

 length of pronotum, scarcely thicker at apex; III linear, one-half length of 

 II ; IV fusiform, equal to III. Pronotum closely, finely punctured, callosities 

 polished; carinate sides a little expanded anteriorly but scarcely reflexed, 

 straight, attaining middle of collum. Elytra slightly widened to apex of 

 corium; membrane exceeding the cuneus by two-thirds its own width, sub- 

 hyaline and somewhat opaque and brownish at base and apex, leaving a 

 broad hyaline band at apex of cuneus. Rostrum attaining posterior coxa;; 

 seg. I passing anterior angle of eye. Ostiolar canal distinctly curved anteriorly 

 at apex. Whole upper surface moderately polished, closely minutely punctate 

 except for the smooth areas on vertex and callosities, clothed with soft ap- 

 pressed pale hairs with apparently four longer stiff hairs on head. 



Color, deep piceous or black; seg. II of antennae, except base and apex, 

 elytra, apex of femora and the tibiae rufo-testaceous; sometimes base of first 

 antennal segment, gula, and coxae more rufo-piceous and the subcostal por- 

 tions of the elytra may be infuscated.
