host and its posterior stigmata open at the level of the junction of 

 thorax and abdomen on the dorsal side. The hosts are readily recog- 

 nized bv the swollen abdomen and are very sluggish. The Pipunculid 

 larva works its way out of its host, making a rupture between two 

 abdominal segments. It enters the earth and pupates slowly. Occa- 

 sionally two larvae occur in one host, but in such cases only one 

 develops. The observers did not see the host's phagocytes attacking 

 the parasites. After the parasite emerges the host is left quite empty. 



Attention is directed to the convergence between these Pipunculid 

 larvae and those of some parasitic Hymenoptera, such as Braconids. 

 The authors note the deposition of the eggs in the abdominal cavity, the 

 delicacy of the larval cuticle, the closed stigmata and the absence of 

 tracheae in the young larvae, the presence of an anal vesicle, and the 

 absence of phagocytic cysts. 



The apneustic condition, the absence of tracheae, and the great 

 development of the central nervous system, especially of the ventral 

 chain, are characteristic of the embryos of all the cyclorhaphous Diptera. 

 The reduction of the bucco-pharyngeal apparatus in the first larval stage 

 is to be associated with the internal oviposition and the " plasmophagous " 

 mode of nutrition. The buccal armature is like that of larval Phoridae 

 and Platypezidae. 



New Thysanoptera.* — Richard S. Bagnall describes Homothrips 

 distinctus, g. et sp. n., from Cape Town, differing from all genera except 

 Rhampothrips in its three- jointed antennal style ; Megalurothrips typicus, 

 g. et sp. n., from Sarawak, allied to Physothrips ; Isoneurothrips aus- 

 tral is, g. et sp. n., from W. Australia, with all the characters of Thrips 

 ( + Bagnallia), but having the whole of the upper-vein of the forewing 

 regularly set with setae as well as the lower ; Tetracanthrothrips 

 borneensis, g. et sp. n., from W. Sarawak, belonging to the Trichothrips 

 group ; and various new species, e.g., of Ecacanthothrips. 



8. Myriopoda. 



Symphyla from Algeria.! — Richard S. Bagnall reports on a small 

 collection containing Scutigerella a rum to. S. immaculata, S. spinipes 

 (previously recorded from the north of England), and Symphylella 

 vulgaris.

Peripatus from Abor Country .J— Stanley Kemp gives a full 

 account of Typhloperipatus ivilliamsoni Kemp, already referred to in 

 this Journal. § It was first found by the late Mr. Williamson on a 

 plateau above the Dihang River in the Abor country. No member of 

 the Onychophora has been hitherto known to occur within the limits 

 of the Indian Empire. No trace of the eye is visible externally, but
