the latter collection. The specimen in the Brussels Museum is some- 

 what doubtfully referred to this species, and the same is true of 

 B 19982, which lacks the antennal funiculi. 



JPlagiolepis squamifera Mayr.

The worher of this form differs from that of klinsmanni in the 

 shape of the thorax and petiole, the mesoepinotal constriction being 

 deeper and the epinotum more cuboidal and less rounded and the 

 petiolar node much compressed anteroposteriorly so that it is high, thin 

 and transverse, with a sharp border, which is feebly emarginate in the 

 the middle. Joints 2 — 5 of the funiculi are about as long as broad. 

 The pilosity is much as in Minsfnanni, but the hairs seem to be a little 

 finer and sparser. 



Four specimens are referable to this species, 3 in the G-eolog. Inst, 

 Koenigsberg Coll, (B 5199, and 2 without numbers) and one in the 

 Klebs Coll. (K 905). The last is very defective as it lacks large portions 

 of the legs and antenna?. Mayr's type (7521/235) in the Geolog. Inst. 

 Koenigsberg Coll. is still in a fine state of preservation and in excellent 

 position.

Mayr based this species on a single female specimen in the Menge 

 Coll. It might be regarded as the female of P. klinsmanni notwithstand- 

 ing its length of about 5,7 mm, since the females of the recent species of 

 Plagiolepis are often considerably larger than their workers, were it not 

 that the pilosity is much less abundant and joints 3 — 5 of the antennal 

 funiculi are much broader than long, I have not been able to find any 

 specimens of this species in the collections I have studied. It is also 

 possible that it is a species of Drymomyrmex (vide infra).

This species was based by Mayr on a single male in the Coll. 

 Menge. He admits that it may belong to one of the preceding species
