It is, however, sin:iller, and at once distinijuislied from Say's species 

 by the broader head, pro])ortionately narrower thorax, and broader 

 first segment of al)domen. There are two, instead of four, pale S230ts 

 on tlie second segment, and altliough this is tlie case also with a va- 

 riety of quadrif/ntfata, the spots in wickhanii are placed much further 

 apart than the corresponding (viz. posterior) spots in that species. 

 Tlie metathorax is also m(jre rounded posteriorly in urickhavii than 

 in qaadrigattata. The quadrujuttata used for comparison is from 

 Lincoln, Neb. (Shiniek), sent by Mr. Wickham. 



Siilia^i'oplilliiilina .»>ea*voIella n. sp. 9 • — About 5 mm. long. Head 

 very largo, quadrate, wider tliau thorax, ferruginous, elothed above with appressed 

 shining pale golden hairs, with some erect hairs interspersed. Anteiuise ferru- 

 ginous, with the ti])S l)ecoining fuscous; tips of mandibles black. Thorax small, 

 scarcely longer than the transverse' diameter of the head, ferruginous, rugose, 

 with scattered, erect, pale hairs ; sides excavate, the excavation smooth and shiny ; 

 metathorax obliquely truncate, the hairs on it longer than other parts of thorax. 

 Legs ferruginous, sparsely hairy. Abdomen pyriform, ferruginous, with spai-se. 

 shining, whitish pubescence, both ei-ect and appressed ; first segment gradually 

 widening, broadly sessile with second ; second segment with its posterior (caudad) 

 half blackish, the blacki&h coloration extending forward in a suffused manner 

 on mid-dorsnm, but interrupted on each side by a large, whitish patch or spot 

 situated about the middle of the segment; these spots owe their whiteness to 

 appressed shiny white hairs, situated on a pale ferruginous ground, which is 

 easily seen between them ; last segment subfuscous.

Judging from the description, this may be the western represen- 

 tative of the eastern S. sccevola Blake, but, as will be seen on com- 

 ])tiring the descrii)tions, it is smaller and differs in color. In its type 

 of eohjration it stands somewhat between ferrugata and qnadnguttatu, 

 though very difierent from either. 



[NoTK. — Scievulella is not related to scsevola, as it approaches .'^..mliiuHssima and 

 cdwuleims. species of a widely differing group. It is most closely related to 

 minntisshna, being somewhivt larger, the hind angles of head not so sharp and the 

 metathorax is not denticulated. — W. J. F.J 



Spliteroplitlialina rulbsufriiJ^M n. sp. 9- — About 12 mm. long. Head 

 rounded, reddisli brown, btcoming l)hickish on cheeks and occiput, covered with 

 dense, coarse, appressed golden hairs, with a few erect black hairs interspersed ; 

 scape of antennae with golden hairs, flagellum black; mandibles huig, blackish 

 with brown bases, with the denticle about twice as far from the tip as in wickhami ; 

 eves large, more precisely circular than in wickhami. Thorax about as broad as 

 head, pyriform seen from above, quadrate seen from the side, reddish brown, 

 rugoso-punctate, reticulate on metathorax ; sides little constricted ; pubescence 

 of dorsum of thorax taking the form of three broad transverse bauds, the first 

 black, the second golden, the third (more sparse) black ; all these colors being 

 modified somewhat by the rufous dermis showing between the hairs. The ante- 

 rior edge of the golden band is practically straight, whereas its posterior edge is 

 convex. Legs rufous, with sparse, long, pale yellowish hairs; coxfe, ends of 

 femora and tibiie, and tibial spines black, or nearly so : tibial spurs finely serrate.
