 brassica, W. Custer Co. ; Formica fusca, L., Swift Creek, Custer Co. ; Metrocampa 

 perlata, Guen., Swift Creek, Custer Co., this is considered to be margaritata by some 

 authors, it seems to me at least a good variety. Qlaucopteryx casiata, Bork., 

 Wellsville, Fremont Co. ; Salebria fusca, Haw., Badger Creek, Fremont Co. ; 

 Menopon pallidum, Nitzsch, W. Custer Co.; Aspidiotus nerii, Bouche (on imported 

 lemons), Silver Cliff, Custer Co. ; Aphis brassiccB, L., W. Custer Co. Of course a 

 large number of other species have been recorded by others ; I learn from 

 Dr. Hamilton that the Coleoptera common to Europe and recorded from Colorado 

 are especially numerous. Many of our species may be termed representative ; for 

 instance, in W. Custer Co. we have Arctia parthenos, a Caia-\i\e species of great 

 interest, in which the ground-colour of the secondaries is ochreous-yellowjjmuch like 

 some aberrations of caia ; and Smerinfhus Astarte, Streck. (which is said to = ceriysi, 

 Kirby), taking the place of ocellatus. I have found what must be its larva on 

 Populus tremulo'ides, but have not yet bred it, though I have obtained the perfect 

 insect. The larva is apple-green, with the usual markings of a Smerinthus larva 

 indicated in pale yellow. The anal horn is blue at the base above, but otherwise 

 purplish inclining to pink, and with a black tip. — T. D. A. Cockekell, West Cliff,

Two new species of Hemiptera on mistletoe. — In the " Revue d'Entomologie," 

 Tome vii, pp. 365, 366 (1888), Dr. A. Puton has described the undermentioned two 

 species of Hemiptera- Heteropter a taken on mistletoe (Viscum album) in the environs 

 of Paris. These should be of special interest to British collectors, for it is not at 

 all improbable that both may be found in England. The mistletoe is not common' 

 near London, but it abounds in Herefordshire, and occurs frequently in other 

 counties ; it has been but little visited by Hemipterists, and an investigation of it in 

 July and August would be very likely to add these two species to the British list. 

 The following notes present the chief prima facie characters of the species, and if 

 any one is fortunate enough to obtain from the mistletoe Capsidce at all accordant 

 with these indications, further information as to details can be had by reference to 

 the full descriptions, I. c. : — 



Lygus viscicola, Puton. — Oval, pale yellowish ; elytra covered with short, 

 depressed, silvery pubescence, and crossed by two black-brown bands ; membrane 

 blackish with red nervures, and with four white spots. Length, 4 mm. 



Resembles Lygus limbatus, Fall., and L. adustus, Jak., but is smaller, and 

 without silky hairs and black points on the tibiae ; ranges best in the group of 

 campestris. 



Sthenarus visci, Puton. — Oval, almost truncate at the extremities. Above 

 opaque-black, covered with scaly, silvery, pubescence ; cuneus very declivous, the 

 margin red ; membrane black with gi'ey nervures ; wings shaded blue, iridescent. 

 Length, 3 mm. 



Has somewhat of the aspect of Charagochilas Gyllenhali, but belongs to quite 

 another group, near Agalliastes. — J. W. Douglas, 8, Beaufort Gardens, Lewisham: 

 March Uih, 1889.
