Bagnall, R. S.: On a small collection of Thysanoptera from Hungary

THYSANOPTERA FROM HUNGARY. 373 4. Zygothrips minutus UZEL 1895 (Pl. XII. fig. 10—12). There is a single mutilated female in the collection taken by Mr. BIRO at Izsák, May 21st 1904, with M. lativentris («in arenosis »). Although the specimen is a large one (1'3 mm.) and has the antennae and the fore and intermediate legs broken off there can be little doubt as to its indentity. The wings are very clear and have the cilia rather widely separated and more than usually long. 5. Hindsiana flavicincta KARNY (Pl. XII. fig. 7 — 9). Hindsiana flavicincta, K ARNY , Mitteilungen des Naturwissenschaftlichen Vereines an der Universität Wien, VIII. Nr. 2, p. 11—12, tab. V, fig. 16—17.(1910). Forma brachyptera. The coloration of this pretty little insect is distinctive. The head, first two joints and the tip of the antennae are light brown whilst the rest of the antennae, all the legs and the thorax (excepting for a slight brownish tinge in the mesothorax) are light lemon-yellow. The species is long and linear and has heavy hypodermal pigment­ation in a line down each side of the abdomen remote from the edges and stretching lightly across some of the segments. It measures 1*5 mm. in length and is 0*22 mm. wide across the mesothorax. Though the wings are reduced there are two pairs of strong wing-retaining spines on each of the abdominal segments three to seven. The genus so far as I understand is closely approximate to the genera Anthothrips, Cephalothrips and Zygothrips. In fact I had set apart the single example herein recorded as a new species of Ceplialo­thrips some time before Mr. KARNY published his paper, and I am not at all satisfied that the species possesses characters of generic value. I feel that as yet the limitations of certain European genera in this sub-order are very imperfectly understood, and, whilst acknowledging the necessity of subdividing certain unwieldy Terebrantian genera such as Euthri])S and Thrips I feel that it would be a pity to regard as distinct though closely allied genera, several allied species that might more conveniently and more satisfactorily be grouped in one or two larger genera. As regards the present species, whilst not acknowledging its generic distinctness at the moment, I can only admit that I have seen but a single poorly preserved specimen whereas KARNY has had the oppor­tunity of studying examples of both the macropterous and brachypte­rou8 forms.
