species, originally collected by Mr. Koebele near Sydney, New Sonth 

 Wales (see Bull. No. 21, Division of Entomology, p. 24), turned up the 

 present year in a rather amusing way. In the March number of 

 Entomological Xeirs (vol. iii, 1892, p. 51), Dr. F. E. Blaisdell describes 

 a new Californian Scymnus under the name of 8. lophaniJuv. He found 

 it preying on the San Jose Scale {Aspidiofics perniciosus), wliich infested 

 the limbs of Acdcia lophanthw at the Coronado Parks, near San Diego 

 in southern California. It is a very incousi)icuous species of reddish 

 color, the thorax often having an iudeflnite dark spot on the disk, and 

 the elytra being of a blackish bronze color. The last-mentioned char- 

 acter is foreign to our native species of Scymnus, which never show any 

 trace of metallic color, and, for this reason, I at once susi)ected, upon 

 reading the description, that *S'. lophuithw was one of the species in- 

 troduced from Australia. Upon comparing Dr. Blaisdell's description 

 with the sample specimens sent by Mr. Koebele from his first and 

 second trips to Australia, I had no difficulty in identifying ;S'. Jophanthcc 

 with the species from Sydney mentioned above. Subsecpiently Mr. 

 D. \V. Coquillett sent me a specimen, recently captured near Los 

 Angeles, which fully confirmed this identification. Whether or not the 

 species has l)een previously described from Australia I have no sj^ecial 

 means of knowing, but it does not ai)pear to be among tliose described 

 by jNIr. Blackburn in ]8o9. (Trans., etc., Eoyal Soc. South Australia, vol. 

 XI, pp. 191-198.) It is closely allied to H.fuyus Brown, from New Zea- 

 land, and distinguished therefrom only by its finer and sparser elytral 

 punctations and the greater extent of the pale thoracic color. 



Dr. Blaisdell does not mention in liis description the structural char- 

 acters of the species, the more important of wliich are as follows : 

 Prosternal lines long, straight, and slightly converging anteriorly; 

 post-mesocoxal line slightly reascending externally; post-metacoxal 

 line complete, almost reaching the first abdominal suture; elytral 

 epipleurie horizontal, reaching beyond third abdondnal segment, 

 slightly concave; inner marginal line not leaving the margin. 



The beetle and its larva are quite abundant in the Coronado i)arks, 

 according to Dr. Blaisdell; and since it also occurs near Los Angeles, 

 there can be no doubt that this useful little Coccinellid has fully es- 

 tablished itself in southern California. 



This was followed by a short paper, being —

In Insect Life (vol. iv, p. 348) are given some observations of mine 

 relative to the destruction of Aphides by this mollusk. While the con- 

 clusions there reached, viz, " that the instance observed was excep- 

 tional and probably does not promise any particular benefit," are per- 

 haps correct, yet some further observations may place the matter in a
