102 South African Beetles 
separable from Drypta ru/ficollis, Desj., but its pectinated claws 
demonstrate its arboreal habits and differentiate it from all the 
species of Drypta. 
Eunostus @uENzII, Chaud. 
This is another rare insect, and I have only obtained it on two 
occasions, each time at light, viz., at Lower Umkomaas in November, 
1898, and at Malvern on 30th December, 1901. Only one other 
species of this genus, H. Jatreil/ei, Casteln. from Madagascar, has so 
far been recorded, and nothing I believe is known of its habits beyond 
what may be surmised from its simple claws, 
Tring HELLUONINI. 
MACROCHILUS APPROXIMUS, Pér. and M. porsatis, Klug. 
These are closely allied species, doubtfully distinct from one another. 
The example of M/. approximus in my collection is larger than J. 
dorsalis, agreeing in this respect with the dimensions given by 
Dr. Péringuey in “Catalogue of Coleoptera of S. Africa” (1896)*, page 
167. M. dorsalis, Klug. is there recorded from Cape Town only. In 
the Munich Catalogue its habitat is given as Jndia orientalis, which 
Dr. Péringuey considers erroneous. The two examples (one of each 
species) were taken at Malvern, Natal; JM. dorsalis at light in 
October, 1913, and J. approximus under stone on 16th October, 1908. 
Many species of this genus appear to have a wide range, but to the 
best of my knowledge are infrequently met with. 
MACROCHILUS VARIANS, Pér., var. ? 
A single example received from the Rev. J. A. O’Neil, on loan, who 
captured it at Salisbury, Rhodesia, 22nd December, 1917. It agrees 
in all essential points of shape and sculpture with Dr. Péringuey’s 
description, except that no mention is made of the broad medial 
longitudinal groove to the prothorax, and its very fine central line. 
In details of coloration the species shows considerable differentiation. 
Dr. Péringuey mentions having two examples before him “in one of 
which the elytra are concolorous and in the other there is a yellowish 
red band beginning near the base and extending, on the fourth and fifth 
intervals, to a short distance from the median part of the disk.” The
