caps a saltitans, Westw.). — Prof. Poulton exhibited the 

 moth and pupa-case, as well as the Euphorbiaceous seed 

 from which both had emerged, having pushed open the hinged 

 lid prepared by the larva. Another seed containing a dead 

 larva, but nevertheless prepared for emergence, was also 

 exhibited. 



Mr. Durrant remarked on the extraordinary number of 

 current errors in connection with this insect. Both generic 

 and specific names were incorrect — indeed saltitans, Westw., 

 did not even exist. Errors were also current with regard to 

 the habitat, the food-plant, and the native name, and even 

 the genus, of the latter. 



Larval hairs of Anergates atratulus. — Mr. W. C. 

 Crawley exhibited drawings of five different varieties of 

 hairs on the larva of the parasitic ant Anergates atratulus, 

 comprising small bush-like hairs with truncate points ; similar 

 ones but with fewer branches and acuminate points ; longer 

 ones with a bunch of points at the apex; still larger ones, 

 straight with one or two sharp lateral spikes ; and longest of 

 all, curved spring-like hairs with anchor-shaped tips. A 

 single bush-hair of Tetramorium caespitum (the host) larva 

 was given for comparison. It was similar, but much less 

 developed than in Anergates. (See PI. A.) 



Mr. Crawley enquired whether similar hairs were known 

 to exist in other larvae, and though such extremely ramose 

 hairs appeared not to be known, the Rev. F. D. Morice 

 said that ramose hairs occur in the larvae of two genera of 

 Sawflies, and in the imago of most bees. Dr. Chapman 

 observed that branched hairs occur in the larvae of many 

 Lycaenids, and Dr. Gahan added that they occur also in some 

 coleopterous larvae.
