example labeled "Md., June rSth, on Willow," and two small brown 

 males from Nevada. 



2. Pediopsis basalis, n. sp. 



Form of/", nassata Germ. Ferruginous ; abdomen olive green ; elytra pellucid, 

 slightly clouded at base and npex, a dark piceous band on tlie base bordering the 

 scutellum. Length, 5 mm., 9- 



Head pale below ; face finely and obscurely punctured, above with the central 

 smooth line and radiatini^ rugre almost obsolete ; eyes and ocelli black. Pronotum 

 finely wrinkled ; central smooth line nearly obsolete ; posterior edge broadly, not 

 angularly, concave. vScutellum finely punctured, darker at the basal angles. Elytra 

 thickened and distinctly wrinkled on the base of the clavus, which is marked with a 

 broad piceous band contiguous to' the scutellar margin ; base of the corium and apex 

 broadly suffused with pale yellowish brown. Abdomen dirty olive green, the edge 

 of the segments paler. Valves yellow, tipped with green. Tip of the tarsi brownish. 



Described from a single female specimen, taken near Muskoka Lake, 

 about the first of August, 1888. This large distinctly marked form can 

 not be confounded with any other described species. 



3. Pediopsis ferrugineoides n. sp. 



Form broad and stout. Color I'errugmous, lower half of the face and all beneath 

 yellow, apex of the elytra and a transverse band beyond the middle subhyaline ; pro- 

 pleiua with a black spot. Length, 5'- — 6 mm., width of pronotum about 2 mm. 



Vertex viewed from above very narrow ; face broad and short, with coarse, 

 shallow, not very distinct rugse and punctures ; frontal suture almost obsolete ; lorce 

 narrow, inconspicuous, quite widely margined by the cheeks ; clypeus broad and 

 short, scarcely projecting beyond the lorse, surlace broadly impressed before the tip 

 which IS rounded, base tumid with a central depression ; tip of the rostrum black. 

 Pronotum darker on the disk ; an elongated yellow spot behind the eye, more or less 

 distinct, and a trace of the same color at the apex ; rugae distinct but not conspicuous; 

 posterior margin rather deeply concave. Scutellum coarsely punctured with five 

 yellow spots, two placed within the basal angles, two smaller ones on the middle of 

 the lateral margins, and an abbreviated longitudinal line on the middle of the base ; 

 apex yellowish. Legs pale yellow. Abdomen bright fulvous, the venter paler. 

 Elytra ferruginous, paler towards the apex ; a transverse band near the tip of the 

 clavus and the apex more or less distinctly subhyaline, the included ferruginous band 

 may be reduced to a spot on the apex of the sutural margin by the costal coalescence 

 of the clear bands, veins concolorous. Wings milky transparent, veins white. 



Montana. Two examples, both females, -received from ]\Ir. Uhler. 

 One, a pale individual, evidently immature, exhibits but traces of the 

 yellow markings on the pronotum and scutellum. This is the largest 

 species of /'^^//o/i^?^ that has come under my observation. It is well 

 distinguished from all our other species by its short tumid clypeus and 

 depressed lorte. 



4. Pediopsis insignis n. sp. 



Dull yellowish brown O, or blackish brown (^ ; covered with a white bloom 

 when fresh ; elytra with a small pale spot beyond the middle ; pronotal rugre very 

 distinct. Length, 1^, 4 mm.; ^, 4^ — 5 mm.
