186 ENTOMOLOGICAL NEWS. [June, 



and Macronychus. I used a fine brass-wire sieve, lifting the stones 

 with the plants attached into the sieve; returning to the bank I had 

 a white muslin cloth spread on the ground; distributing the plants 

 on the cloth, many of the beetles left immediately, others I ob- 

 tained by pulling them from the stones and washing them in the 

 sieve; then using a lens in finding them; also picking them out 

 of crevices with the point of a small pocket knife. I found plants 

 growing on the slag, from an iron furnace, the most favorable 

 for that kind of collecting. This portion of my work was at a 

 depth of 8 1 6 inches of water. I also tried sinking pieces of 

 wood, securing them by weights, which yielded a few specimens 

 each day.

Leucarctia rickseckeri. 



Mr. L. E. Ricksecker has kindly presented to the American 

 Entomological Society a pair of the fine species named in his 

 honor by Dr. H. H. Behr in " Zoe," vol. iv, p. 247. L. rick- 

 seckeri may be described as follows : 



It is about the size of small specimens of L. acrcsa. The wings of the 

 female are immaculate, except a minute black discal spot on anterior 

 wing. Body similar to L. acrata, but with the black spots fainter, some- 

 times obsolete. In the male the thorax and anterior wings are a diffused 

 smoky color, immaculate, except the minute discal spot ; posterior wings 

 yellowish brown, with one discal and two or three submarginal spots quite 

 indistinct and nearly obsolete. Both pairs of wings are brown underneath, 

 with a few variable, obsolete, black points. 



Mr. Ricksecker speaks of the species as follows: "June n, 

 1891, I found three larvae about full grown, similar in general ap- 

 pearance to those of L. acrcea on a species of Senecia. They 

 commenced spinning cocoons June 18, and three males emerged 

 July 18, 1891. June 18, 1893, I visited the same place, and after 

 a long day's diligent search I had twelve caterpillars. June 15 

 they commenced spinning cocoons; June 20 eight cocoons (the 

 remainder escaped from the cage); July 5-12 six imagines $ 2, 

 94. Two cocoons contained parasites. Locality, Sonoma Co. , 

 Cala." (We have reproduced the above for the benefit of those
