General Topics. GLOVERIA. By Dr. M. Draudt. 
does not agree with the general opinion that the old silk only originates from G. psidii, but supposes that parti¬ 
cularly also Saturnidae such as Gallosamia, Telea and Attacus are to be taken into consideration for it. The larva 
of psidii has hair which, like that of the larva of rubi, cause disagreeable burning sensations on the skin, 
especially on the back of the hand. Biologically interesting are also their enormously large nests ,,being parti 
cularly before the beginning of the rainy season of a glary white colour and often attaining a length of one 
meter“. The silk of psidii cannot be reeled off, but only combed. 
The systematisation of the American Lasiocanipidae does not cause the difficulties of other faunal 
regions, because there are fewer genera, part of which at least exhibit such a characteristic exterior that the 
enlisting of a species is mostly made rather easy. For this reason an analytical division of genera is also unne¬ 
cessary, for the few principal groups are quickly and clearly identified. It is only difficult in certain cases 
to define Tolype from Titya, as well as Nesara (Ocha ) from Euglyphis. In America only the subordinate 
groups of the Lasiocampinae and Malacosomatinae in Aurivillius’ sense are represented. 
Much more difficult, however, than the systematisation of the genera is the distinction of many species. 
This is chiefly due to the rareness of many species which are only known from single specimens and are often 
extraordinarily alike, and above all to the wrong identification of the types. The majority of the Lasiocampid 
types is now in the National Museum of Washington, after the Collection Dognin had been annexed to it, and 
chiefly owing to the great obligingness of Mi'. W. Schaus we succeeded to some extent in putting this difficult 
group in order. Kirby, in his Catalogue, combined a great medley of insects that did not belong at all to 
the Lasiocampidae. A number of Walker’s and Felder’s types do not exist any more, so that.we shall never 
succeed in perfectly clearing up all the questions. Mr. Schaus greatly facilitated our task by grouping for us 
a synonymic list of the species contained in the Washington Museum, which afforded great difficulties, as well 
as by having a great number of species most perfectly painted for our plates by Mr. Francis H. Noyes, so 
that we are able to figure such a great material as has never yet been put together. Mr. W. H. T. Tams, 
in London, by examining the genital armature of doubtful species of Prorifrons, has contributed a great deal 
to clearing up this genus. All these facts prove that the American Lasiocampidae are still very inaccurately 
known and that by further examinations of the genital organs many questions must yet be solved, before we 
shall be able to specifically define numerous forms to a certainty. Then only a satisfactory grouping will be 
possible, which we must therefore leave to the future. 
The Lasiocampidae are species of very large to small sizes, without a proboscis, with mostly short palpi, 
a hairy abdomen which is often very long in the 33- The broad lobate projection of the costal margin of the 
hindwing often occurring in other faunae, is mostly quite absent in the American species. The discal cells of 
both wings are mostly narrow and short, the cross-vein of the hindwing is often very oblique. In both wings 
vein 5 rises from the lower cell-angles, vein 6 from the upper ones. The ,,basal cell“ being formed by 8 anastomo¬ 
sing with 7 on the hindwing is mostly very small or rudimentary. 
1. Genus: Ciloveria Pack. 
Well characterised by remarkably little, hairy eyes, short porrect palpi, and in both sexes pectinate 
antennae, in the female with short pinnae. The abdomen is long, in the 3 with a parted anal tuft. The veins 
exhibit few differences in all these large Lasiocampidae ; on the forewing the cell is relatively narrow and short, 
9 and 10 are stalked, 6 rises on a short stalk with 7 from the upper cell-angle, 4 and 5 from the lower cell- 
angle, 2 and 3 rise at about equal distances between the base and the cell-angle. On the hindwing 7 and 8 
rise from a strongly developed basal noose, 4 and 5 on a rather long stalk rise together with 3 from the lower 
cell-angle. Both sexes are dissimilar, the 3 is often scantily scaled in the disc. 
The large Lasiocampid species have been carefully examined by Barnes and McDunnough, whereby 
they had to be divided into various genera, the arrangement of which was fundamental for our work. 
Type: G. arizonensis Pack. 
arizonensis. G. arizonensis Pack. (76 a) is easily recognisable by the strong black neuration and the extraordinarily 
strongly notched subterminal line; both the transverse lines are rather distinct, particularly the posterior line 
which is pointedly inwardly dentate on the veins and between them projects feebly rounded distally; discal 
dolores. and marginal areas usually darkened, in the former a distinct white discal spot. — f. dolores N. &. D. is based 
upon specimens in which the subterminal line is not uniformly parallel to the margin, but is bent towards 
the base above the anal angle and between the radials. Nothing has yet been published about the larva, although 
the species has already been bred. Colorado, Arizona, South California.
