hind, and with a circle of minute prominences (probably micropylar) in front. In hat- 

 ching the egg-shell ia split longitudinally in front, but no cap nor any other part is 

 cast oif. The egg-stage lasted 3 weeks, and the ist, 2^^, 3rd^ and 4tii instars lasted re- 

 spectively about 7, 9, 6 and 3 days: the insects died before reaching maturity. In the 

 Ist instar the insect posaesses certain special tubevcles and hairs which are all got rid of at 

 the first moult: the wing-pads appeared at the third ecdysis. Tlie insects were fed on 

 grass, into the green parts of which they plunged the rostrum, sometimes keeping it 

 inserted for some hours. Their curious attitudes while feeding and resting are described.

 cing Psyllid from Syria, In: Ann. Mag. Nat. Hist., Bd. 2, No. 63, S. 306 

 —308, Taf. 7, 1913. 



A giant gall is described, measuring 180 mm in lengtli and 5 — 26 mm in 

 width, roughly cylindrical, and pointed at the tip. When found it contained im- 

 mense numbers of immature Psyllidae, probably a species of Triozinae. The in- 

 sects are described, but cannot be determined owing to their immaturity. The 

 gall is probably the largest Psyllid-gall known. H. Scott (Cambridge).

This is a report on the material collected by the Percy Sladen Trust Expedition 

 to the Indian Oceau. It deals with 58 spjj., niost of which are new, and includes de- 

 scriptions of 2 new genera of Ephydridae. The few spp. which are not new have wide 

 and curious distributions, beiug known in one case from the Mediterranean Region; in 

 another case from S. Europe, Egypt, and Natal; in another from Madeira; in another 

 from the East Indiea. H. Scott (Cambridge).

 which occur in certain characters of Änopheles larvae in the course 

 of their growth. In: Bull. Ent. Research, Bd. 3, Heft 4, S.387— 391, 6 Text- 

 fig., 1912. 



The determination of the spp. of AnopJieles from an examination of the lar- 

 vae has been hampered by the apparent variability of important larval charac- 

 ters in different larvae of the same sp. In the Malay Peninsula the writer has 

 bred out certain spp. from the egg and studied the larvae in their successive 

 stages. He considers that the supposed variations of the larva of a sp. may re- 

 ally be "changes of a constant kind associated with successive phases of deve- 

 lopment". Certain changes observed during the growth of the larva of Anoplieles 

 albirostris are described in detail and illustrated. In the newly-hatched larva of 

 this sp. the clypeal hairs are simple bristles and the dorsal "palmate" hairs are 

 represented by simple lanceolate leaflets. During growth and at successive ec- 

 dysis gradual changes occur, so that finally in the mature larva the clypeal hairs 

 are much feathered (and the position of the posterior ones is different from what 

 it was), and the simple leaflets are replaced by the whorls of leaflets forming 

 the palmate hairs. The newly hatched larva of this Änopheles approximates in 

 several of its characters to mature CwZfic-larvae. H. Scott (Cambridge).
