Lysiphragma howesii (mixochlora). Not uncommon. Its pupal cocoons may be found in similar situations to those of epixyla, but are not so conspicuous, being often almost hidden in the substance of the bark. Mr. Ambrose Quail described this insect as howesii, but Mr. E. Meyrick's description of mixochlora seems to me to fit it very well, and I have some doubts of its distinctness. Porina dinodes. I took about a dozen examples of this handsome moth at light in March, 1902. The larvæ live on the roots of grasses, and inhabit deep tunnels lined with silk. When full-grown they are nearly 4 in. long, and much lighter in colour than the larvæ of despecta or cervinata, being whitish-ochreous, with paler neutral surface and darker thoracic segments. The head is bright brownish-red. The tunnels are driven in rather an oblique direction to a depth of from 15 in. to 20 in. Three examples which I tried to rear pupated about the middle of August, but failed to emerge from that state. I am strongly of opinion that the larva of this moth is the “vegetable caterpillar.” No other moth in this district known to me is large enough to warrant the assumption that its larva may be the host of the fungus. I have several times found the fungus-attacked larvæ here, and, as far as a comparison between these and the living larvæ of P. dinodes can be trusted, I think it bears out my opinion. P. cervinata. In November, 1900, I was successful in taking for the first, time females of this species. They are very rare in comparison with the males, and are duller in colour, with fewer markings.

Art. XIX.—Notes on an Insect found in some Hot Springs at Taupo. By J. W. Poynton. [Read before the Wellington Philosophical Society, 2nd September, 1903.] About a mile from Lake Taupo, close to the Taupo-Napier Road, are the well-known hot springs locally named the “Black Terraces,” from the terrace-formations of dark colour formed by the principal springs. The terraces are of the usual kind. There is a pool of water confined by a rim of siliceous deposit. The hot water flows over this rim at the lowest part and falls into another basin below. There are perhaps a dozen of these small
