28*^' August, 1889. — 1) Botanical. — 2) Pielus hijalinatus and its 

 Allies: a Rejoinder. By A. Sidney Olliff, F.E.S. In this note Mr. OllifF 

 re- asserts his opinion as to the distinctness of Pielus imperialis and P. hya- 

 linattis, and makes some remarks with regard to the distribution of these 

 species and their allies, which he thinks may be conveniently divided into 

 two groups according to the unipectinate [Pielus) or tripectinate [Pstudupielus) 

 structure of the antennae. — 3) New species of Lampyridae, including a 

 Notice of the Mt. Wilson Fire-fly, By A. Sidney Olliff, F.E.S. A short 

 paper containing a review of the Australian Lampyridae with special refe- 

 rence to the luminous species. The 'Mt. Wilson species is described under 

 the name Cratomorphus lynchus, and some observations are made concerning 

 its light, which is stated to be intermittent and to some extent under the in- 

 sects' control. It is conjectured that this particular fire-fly, or an allied form 

 regarded in this paper as the C. licolor, Fabr., is the ,,New Holland 

 species", which Carus, as long ago as 1824, stated, on the authority of 

 Long, to be possessed of a light which varies in intensity in ,, rhythmical 

 vibrations". — Mr. Skuse exhibited specimens, both pupae and flies, of 

 a new species of Cecidomyia, together with the galls formed by the insects 

 upon the branches of Acacia lonyifolia. The galls are cylindrical, from 12 to 

 18 mm long, and occur in closely packed bunches of from two to twenty or 

 thirty tubes. When found at the beginning of August, each tube contained 

 a full-grown pupa inclosed in a white cocoon at the bottom of the tube. 

 Also, specimens of a minute Hymenopterous insect belonging to the genus 

 Plutygaster, some small beetles belonging to the Mycetophagidae, and a small 

 moth, all likewise bred from the above-mentioned galls. — Mr. A. Sidney 

 Olliff exhibited the Fire-flies described in his paper. He also showed a 

 finely coloured male specimen of Pielus iinperialis, O. & P., caught early in 

 July on a lamp post at the North Shore, Sydney, by Mr. M. V. Miller. — 

 Dr. Read showed a specimen of the Frigate or Boatswain Bird in its first 

 plumage, from Lord Howe Island.
