DESCRIPTION OF TWO NEW NORTH AMERICAN SPECIES OF HETER- 



OPTERA. 



Dendrocoris pini Montandou. 



Oval; pale yellow ocliraceous; above coarsely and densely, beneath 

 more finely punctured, concolorous. Head as long as broad (including 

 the eyes), the vertex moderately convex. AutennsB brownish red, 

 with the third Joint twice iis long as the second, shorter than the first 

 and second together; joints 3, 4, and 5 equal in length. Pronotum, 

 with a short longitudinal callus, smooth to the middle of the anterior 

 margin, with the cicatrices of each side at the anterior part of the pro- 

 noiuni slightly elevated and partially smooth; the lateral margins of 

 the pronotum straight, anterior angle very slightly notched, humeral 

 angle obtuse, not prominent; margins of the scutellum with small, 

 sliining, and slightly elevated i^ale spots. Elytra with a small impunc- 

 tate portion in the middle of the disk, lateral margins occasionally with 

 pale spots like those of the margin of the scutellum. Membrane reach- 

 ing the extremity of the body, concolorous, with the body and with the 

 nervures very slightly apparent. Connexivum separated from the elytra, 

 concolorous and densely punctured; the segmental sutures slightly 

 elevated. Rostrum brownish red, reacliing the posterior coxaj. Ex- 

 tremity of the femora and of the tibia) and tarsi more or less reddish 

 brown. 



Male and female: Length, 5 to 6"""; width, 3 J to 3f""». Found upon 

 rhnis monophylla in the Argus Mountains, Oal. Collection of the U. 

 S. National Museum and my own. 



The genus Dendrocoris Bergroth (Revue d'Entouiologie, 1891, p. 228) 

 has been substituted for the genus Liotropis Uhler, preoccupied. 



I am of the same opinion as Prof. Bergroth, who says that this genus 

 should not be placed in the subfamily Asopina, in which Prof. Uhler 

 has put it, and it evidently belongs to the subfamily Pentatomina, 

 near the genus Lopadusa Stal. 



The new species just described is easily distinguishable from the two 

 which are recorded in this genus, 7>. humeraUs Uhler and D. frnficieola 

 Bergroth, by its smaller dimensicms, the latei-al obtuse angle of the 

 pronotum not prominent, and the pale color of the body with con- 

 colorous punctures. 



Sinea Rileyi Montandon. 



Ferruginous brownisli with a grayish i^ubescence, very short and not 

 so dense upon the elytra, denser beneath, especially on the breast. 

 Posterior and mitklle femora in the middle and all tibise in the middle 

 l)aler than the body. Head a little shorter than the pronotum, with a 

 double row of tliree sliort s[)in('s before the eyes, the anterior si)ines 

 longer than the posterior, and behind the eyes on each «ide two
