in the abdominal region in close association with the heart in various 

 Orthoptera (Gryllus, Nemolius, GryllotaJpa, Bracliytrypus, Gymno- 

 grilhts). He believes that these organs — two pairs in Gryllus and 

 Nemobius, four pairs in GrgUotalpa, and so on — are homologous struc- 

 tures in Orthoptera. 



New Copeognatha.* — Giinther Enderlein reports on some forms of 

 these remarkable insects, collected by Fr. Dahl in the Bismarck Archi- 

 pelago, e.g. the new genus \Soa, in the family Lepidopsochidas. He also 

 notes that the function of the so-called " stigma-sac " on the under side 

 of the anterior wing of all Copeognatha is to hold the wings together in 

 the resting position. 



New Mallophaga.f — Vernon L. Kellogg gives an analytical key to 

 the two sub-orders and the genera of this interesting but little studied 

 order of parasitic insects. In the order, as at present known, there are 

 about 1500 species, comprising 23 genera. The small number of genera 

 is striking in itself, but it is made more amazing when it is remembered 

 that eleven of the genera comprise but thirty of the species, leaving 

 nearly the whole bulk of the species in the twelve remaining genera. 

 The addition of two new genera— Philoceanus from Procellaria tethys, 

 and Nesiotinas from Aptenodytes longirostris, is therefore rather notable 

 in the development of our knowledge of this order. 



Mallophaga from Hawaiian Islands.! — Y. L. Kellogg and B. L. 

 Chapman report on a collection of twenty species of biting lice obtained 

 by R. C. MacGregor, from twelve species of birds shot in the Hawaiian 

 islands. We note the paper because it reports on the first collection of 

 Mallophaga from this area. Of the twenty species fourteen are named 

 and described as new, four are named and described as varieties of pre- 

 viously known species, while but two can be considered typical repre- 

 sentatives of already known species. Of the twelve hosts, four are 

 peculiar to the Hawaiian islands, and the parasites of these birds are all 

 new species, except the two taken from the Hawaiian coot, Fulica alai. 



Thanasimus in the Himalayas.§ — E. P. Stebbing reports the dis- 

 covery of Thanasimus (near T. nigricottis) in the north-west Himalayas, 

 a beetle belonging to the family Clerida?, which is of great importance 

 because it is predaceous upon several ^wood-boring and bark-boring 

 Scolytidae, detrimental to the coniferous forests of the north-west 

 Himalayan area. 



/3. Myriopoda. 



Sense of Smell in Myriopods.|| — C. Hennings finds that the 

 antenna?, and these alone, function as organs of smell. The strength of 

 this sense varies noticeably in different forms ; it stands in no visible 

 connection with the length of the animals, but more probably has
