Antardia Beanii, v. ficscosa. 



A beautiful variation in which the primaries in ^ and 9 ^•re nearly 

 uniformly brownish-black from base to exterior margin. The triangular 

 spot at costa as well as the mesian line being slightly indicated. 



Types coll. B. Neumoegen. 



It seems to me that Arctia Brucei, Hy. Edw. (Entom. Amer., Vol. 

 III., p. I S3), is not a true Arctia, but very closely related to A. Beanii. 

 Excepting the slight differences of structure in the 9 ? > these insects 

 show conclusively how near our genus Antarctia, Hb., comes to 

 Lederer's genus Oaiogyna. 



All the specimens of ^, Beanii, including its var. y^^j^^^a, having been 

 raised by Mr. Thos. E. Bean, I asked him for some data about the larvse 

 and their life habits, to which he kindly acceded. I publish them here- 

 with in his own words : 



" All specimens are bred from larvse taken (when in or near final stage) 

 near Laggan. Only one imago has been found in the four seasons I have 

 collected here. One $ bred in 1886 from an estray larva was the first 

 seen. In 1888 the imago above mentioned was found. (July 2, a (^.) 

 In 1889, 2 (? c? ) I 9 were bred from estray caterpillars. So up to i8go 

 only six were seen, though I often searched for them. But in June, 1890, 

 I found them more frequent in one limited tract of about two acres — 

 elsewhere none to be found. Larva feeds on willow exclusively, I think. 

 At any rate all I have found feeding were on willow. The imagines bred 

 in 1890 came from pupa chiefly between July 4th and 21st, though one 

 $ delayed until Aug. 4 ; 1890 was a late season. Those bred in 1889 

 emerged June 8 and 24 (2 $ $), June 26 (i 9)- Males and females 

 equally numerous. The $ $ are noticeably larger than the 9 ? > as an 

 average. As to extremes of size, the 9 9 vary most ; there are more 

 extra small 9 9 than $ $ . The $ $ average decidedly darker than 

 9 9 ' Occasional 9 9 a-re extremely dark. This species occurs at an 

 elevation ranging from 4,800-5,000 feet, so far as observed. The mature 

 larva is about 24 mm. long. Ventral and basal lateral region clothed 

 with rust-red hairs. Dorsal and upper lateral region usually has jet black 

 hair, but sometimes some of the hairs are whitish. Hair of median lateral 

 region sometimes black, sometimes whitish." 



Heterocampa nivea, n. sp. 



Antennae slightly pectinated, white above, black below. Head, thorax, 

 abdomen, legs, and both wings white. Thorax and abdomen heavily
