about four in 7$n of the margin ; vasiforrn orifice about 25 /i broad, short 

 and rounded, wiili the broad entire margined oi>crcuIum practically filling 

 the orifice?. In the table by Mrs. Hemis (Proc. U. S. Nat. Mus., XXVII, 

 p. 485), this runs to A. nigratts, but differs in the regularly oval shape ; 

 the adult also is (]uite difTerenl. 



Adult about 1 140 /' long ; body above blackish, covered with white 

 meal, the base and sides of abdomen white, the extreme base of wings 

 yellow ; beneath, the abdomen is light yellow, with the last two segment s 

 gray ; eyes black, completely divided ; wings white, each with a small 

 dusky spot in the apical field, and also two very faint slightly iridescent 

 clouds above the principal vein, one from the dusky spot toward the apex, 

 the other apparently marking the place of the lost upper branch. 



Nearest, I think, to A. Dorseyi Kirkaldy, but the dorsal area of the 

 juipa is nmrh more obtuse posteriorly than in that species, which occurs 

 on Khainims in Cilifoinia. The adult oi A. Dorseyi is unknown.

Pai'KK X. — Nkw Species of Kmpria. 

 Lcpelctier in iSjS (Kncytl. Method, X (2), p. 57 i ), described his 

 genus Empria, and included three species, the first of which, Dolerus 

 ( Empiia) pallimacula Lepcletier, was named as the type by Hrulle (Hist. 

 Nat. Ins. H)ni. I\'. pp. 666, 1S46). 



In 1835 D.ihlbom, in his Conspect. Tenlhrd. Scandin., p. 13, No. 

 VIII, founded the genus /\rci/ostoiita for Tent/noio !;iittatiiin Fallen. 

 Thomson, in 1.S71 (.Scand. llym. I, p. 2^7), changed the spelling of 

 1 )ahll)om's genus, Pivcilostoma, to Ptriilosomti. 



Dr. Ashmead, in his tables in the Canadian KntomoU)C.ist for 1S98 

 (p. 256), made Haripiphorui niaculatus Norton, the type of a new genus, 

 Pctcilostoinithn .nnd .\f,ytio^tf[^ia it^notd Norton, ll:e Ivpc of I'ftt atufut a 

 Ashmead. 



Dolftui (I'.mptia) palltmaiulata I.epeletier, is the same as 

 Tenthredo i^uttittum Fallen, and Haripiphorus maculiUui Norton and 

 Monosttj^iii if^nota Norton, are congeneric with Tenthitiio t^uttatum. so 

 the synonymy of the genus Empria is :
