Præanal scale rather attenuated behind, and with a straight margin. Entirely pale red; antennæ rather lighter. Legs smooth. Length, 4.3 inches. Breadth, .1 inch. Hab. Wellington and Inch Clutha. One specimen has abnormal antennæ of only 12 joints, and the 10th and 11th joints are vasiform. Himantarium morbosus, sp. nov. Fig. 2.

Latero-posterior portion of each segment with fine distant oblique striæ, which are more distinct on the anterior portion of the body than on the posterior, and are very indistinct in the young.
