I40 Annals Entomological Society of America [Vol.1, 



Abdomen but little wider than pronotum. Genitalia pretty much as in 

 scutatus, though the entire sixth segment of the female is relatively shorter, and 

 the ventral pla'te in the male is not so narrow at its middle point. Wings a little 

 longer than abdomen. Whole insect covered with rather dense hair. 



'^ Color, reddish brown with no distinctive markings. The pronotum is 

 sometimes irregularly blotched with black, and its posterior border, with the 

 base of the scutellum may be dark or almost black. Beneath the color is lighter, 

 often tinged with yellow and minutely spotted with red. Sternum black, and 

 often a dark brown line on either side of abdomen below, near the borders. The 

 first and second segments of disk of abdomen are black, and the remaining four 

 may be black also, but usually are brown. The third has two small spots on 

 anterior margin and the fourth a rather large oval spot at its center; the fifth 

 has tAvo smaller oblique spots at its anterior margin and several small round 

 spots below these ; the sixth with the conventional yellow lateral stripes and the 

 long black spot between them. Connexivum alternating dark and fight, some- 

 times one predominating and at others the other. The dark portions are fre- 

 quently ornamented with one or more small round spots of a lighter color. The 

 legs are reddish yellow spotted with brown. Wing veins with a few brown spots. 

 Membrane with'a slight reddish tinge. 



This also is a western species, and was recognized as new by 

 Uhler who proposed for it the name indentatus, but never pub- 

 lished a description. Specimens are at hand from British Col- 

 umbia, Washington, Oregon, California, Wyoming and Colorado. 

 Corizus tuberculatus n. sp. 



]\Iedium in size, with antenniferous tubercles abnormally 

 long. Rather yellowish in color. Length of female, 6 mm., 

 width 2.7 mm. 



Head: Antenniferous tubercles very long, reaching almost to the apex 

 of the head and diverging widely. Rostral lobes small but distinct. First seg- 

 ment of antennae passing the apex of head. 



Pronotum: Transverse suture bordered anteriorly bV a tubercular ridge. 

 Anterior angles not prominent. Scutellum broad at the apex, rounded and 

 excavated. 



Abdomen not much wider than thorax and sides nearly parallel. Genitalia 

 of female very similar to scutatus. Wings equal to abdomen in length. Pubes- 

 cence slight. Punctuations prominent. 



Color: Reddish yello-w, a little darker above than below. Head a fittle 

 more tinged with red. Eyes dark. Small black spots between ocelli and eyes. 

 Posterior angles of pronotum darker. Scutellum light, unspotted. Disk of 

 abdomen black with a small elhptical spot at its center and six smaller ones 

 surrounding, and at some distance from it. Several other very small round spots 

 are scattered over the surface. The posterior border of the fifth and all of the 

 sixth segments fight. The latter has a darker portion at its middle. This spot 

 has the same form as the black stripe that is so common in this genus but is not 

 black as is usually the case. Beneath, the insect is unspotted except the ster- 

 num which is black. 



This insect is described from two females taken by Mr. Hei- 



demann at Pullman, Washington.
