INSECTA, HYMENOPTERA.
MAYR (Verh. zool.-bot. Ges. Wien, xx. p. 940) quotes and partially confirms
Emery's observation that Colobopsis tnmcata is the male and C. fuscipes the
worker of one and the same species. He thinks it probable that all species of
Colobopsis have males and workers, and considers in that case that this genus
has the same relation to Camponotus as Pheidole to Pheidologeton. At p. 941
he tabulates the known Asiatic and Australian species of Colobopsis; and at
p. 944 describes an insect from Tonga, apparently referable as worker to C.
mfifrons, Smith, though in certain points so different from that species as
likely to suggest the formation of a new genus for its reception.
Prenolepis lasioides, Emery, being a true Lasius, is renamed fumatus:
Emery, I. c. p. 194.
Mayr (1. c. p. 947) tabulates the workers only of 9 species of Prenolepis (including
2 new species), and remarks that the Prenolepis from the Taurus, in
nests of which Lederer found a Paussus, is identical with the S.-American
P. fulva. At p. 949 he records P. vividula, Nyl, from Tonga and other islands
of Oceania, with variations of colour &c.; and considers it probable that P.
obscuva, from Sydney, is the type form of this insect.
Mayr (/. c. p. 950) describes worker and cf of Lasius claviger, Rog, from
Connecticut and N. York.
Formica. Map- (I. c. p. 950) compares this genus and Lasius; notices the
affinities of European and N.-American species of the former, especially referring'
to F. ctnicularia, Latr, from Connecticut, and F. cinerea, Mayr, from
California. He names obscuriveutvis a var. of F. tvuncicola, Nyl, from Connecticut,
and indicates a new species near F. Integra, Nyl, from California.
He also mentions workers from N. York and other localities intermediate between
F. fusca, L, and gagates, Latr, and states that only F. schaufussi,
Mayr, is in any marked degree separable from the European species. The
author speaks slightingly of Buckley's ' Descriptions of new species of North-
American Fomricidoe.'
Mayr (I. c. p. 952) describes Spanish specimens of Catagvyphis albicans,
Rog.
llypoclinea. Mayr (/. c. p. 953 et seq.) remarks generally upon the relations
of this genus and of Iridomyrme.r, Doliehodevus, Tapinoma, and Bothryomyrmcx;
divides the workers of llypoclinea into five groups, with observations
upon the geographical distribution of that genus, and fp. 955) tabulates all
the known species. Aceinlholepis kirbii, Lowne, is a llypoclinea, and a good
species ; Formica itinerans, gracilis, and rufmigra, Lowne, and Acaniholepis
mantdlatus, Lowne, are also to be referred to llypoclinea, though with some
doubts as to their specific value; Formica smithii, Lowne, =//. purpurea
Sin.; Acuntholepis tuberculatus, Lowne, =11. nitida, Mayr ; Polyrhachisfoveolafus,howne,
= H. seabvida, Rog.; Polyrhachis cuspidatus, Sm, is & llypoclinea.
Mayr, /. c. p. 054 et seq.
The workers of Liomelopum, Mayr, are to be distinguished from those
of llijpoeUnea by their possessing ocelli, and their longitudinally convex
non-constricted thorax. L. xanthocroum, Rog. (= Iridomyrmex xanthocrom
and I. sericeus, Mayr), however, seems an oscillating form. Mayr, I. c.
Polyergus vufescens. Forel (I. c. p. 306) proves the non-existence of a
sting in this species, which had hitherto been considered the sole aculeate
member of the Formicides. The Formicidce are thus easily sepa-
