F. Low notices his having reared the following species of this group from 
plants not recorded for them by Schiner, namely: — Trypeta colon (Meig.) and 
Urophora solstitialis (Linn.) from Ceniaurm panicxilatum^ Urophora conyrna 
(Low) from Lappa commimisy Tepliritis eluta (Meig.) from Cirsium lanceo-

Calohata. The following 6 new species are described by Loew (Berl. ent. 
Zeits. 1866) : — C. platycncma and C. angnlata (p. 47), from New Granada; C. 
maculosa (p. 48) and C. placida (p. 49), from Cuba ; and C. nchtdosa (p. 48), 
from Florida. 
Psilides. 
Eugene Faulconnier notices the occurrence of a species of Piojdiila in great 
numbers in hermetically closed cavities in blocks of stone, containing the 
remains of toads, enclosed alive for the purpose of experiment by Aug. 
Dumeril. Bull. Soc. Ent. Fr. 1866, pp. Ixviii-lxix. 
Osemides. 
Chlorops. Loew (Zeitschr. ges. Naturw. xxiv. pp. 396-396) refers to several 
species of this genus, namely: — C. spcciosa (Meig.), to which he refers C. nasxda 
(Zett.) except some of its varieties; C. tamiopus (Meig.), to which he thinks the 
statements of former authors with regard to C. lineatus refer ; C. messoria forms 
a distinct genus, Eiplotoxa (Loew) ; C. cereris includes 3 species differing from 
the other species of Chlorops in the general structure of the body, and in the 
absence of a curved spur at the apex of the intermediate tibia, so that they 
may form a distinct genus, Centor (Loew) ; C. tarsata (Meig.) = divergens 
(Loew) ; C. alhitarsis (Meig.) = tarsata (Fall., Zett.). 
Chlorops tamiopus (Meig.). Cohn (.Jahrosber. schles. Gcsellsch. fiir vaterl. 
Cultur, 1866, pp. 71-79) describes the natural history of this species, which 
since 1863 has made its appearance in Silesia as an injurious insect to wheat 
and barley. He also discusses the nature of the effect produced upon the 
plants by the attacks of the larva.
