lad of end of abdomen; membrane ample without spines, delicate, 

 hyaline ; ostiole minute, at apex of short recurved, rather blunt ostio- 

 lar process; beak somewhat surpassing middle coxae; rostral sulcus 

 first evident on mesosternum where it is broad, rather shallow and 

 bounded by the tumid lateral portions of the sclerite, narrowed be- 

 tween middle coxae, then almost regaining its width on metasternum, 

 deep, distinctly margined; broader, rather deep and definitely mar- 

 gined on first abdominal segment; venter with rows of tubercles and 

 small spines across segments. 



Genotype, Saurocoris instans new species. 

 Saurocoris instans new species. 



Structural characters as noted in keys and in description of genus. Gen- 

 eral color stramineous, some specimens almost wholly so, others with head 

 except antennal insertions, and region back of ocelli and anterior lobe of 

 thorax except disk, black ; antennas and legs copiously annulate (bands over 

 expanded portions broader) with fuscous to black; terminal joint of former 

 and tarsi black; venter stramineous. Length 3—3 J^ mm. 



Nymphs, apparently in the last instar have the antennae and legs marked 

 as in adults, the general color shining reddish stramineous. The median 

 series of large spines on head is about as in adult, but remainder of head and 

 upper surface with numerous round tipped spines, in strong rows across 

 dorsal surface of abdomen. 



Type from California, probably Los Angeles Co., collected by D. 

 W. Coquillett. Other specimens are from that county, April (nymphs 

 and adult) ; and Folsom, Calif., July 8, 1885. All in U. S. National 

 Museum.

Head with five antrorse curved spines along median line, de- 

 creasing in size anteriorly, the foremost strongly projecting over 

 base of beak; tubercles and spinules elsewhere, a prominent one 

 behind each antenna, and low, continuous carinae both behind and 

 above eyes; thorax with strong spines on front and lateral margins 

 and in three lines on disk, the tendency of all the spines being to 

 project away from the center; mesosternum not at all swollen, meso- 

 thorax very coarsely punctured; sides of head, basal joint of beak 

 and pleurae more or less bristly spinose ; scutellum with a long, sharp,
