302 SUMMARY OF CURRENT RESEARCHES RELATING TO 



beetle. In the same species and sex the number increases with the size 

 of the body ; there is usually no permanent difference between the sexes, 

 but the numbers for one eye in the male and female are 2500 : 300 in 

 Lampyris splendidula, 5300 : 4850 in Melolontha vulgaris, 2200 : 1800 

 in Saperda carcliarias. The number is greater in the rapidly moving 

 active forms, smaller in the sluggish forms. It is not reduced in noc- 

 turnal forms, as the instance of Necrophorus germanicus $ , with 24,000 

 facets, shows. 



Blind Coleoptera of Australia.* — Arthur M. Lea gives notes on all 

 the known species in Australia and Tasmania. None have been taken 

 in caves ; they occur principally under stones, or at the roots of beach- 

 growing plants. The number of species is eight — probably far short of 

 the total to be obtained — and all are of small size, with the body 

 apterous, and elytra soldered together. 



Insects Injurious to Cocoanut Palm.t — Charles S. Banks describes 

 the rhinoceros beetle (Oryctes rhinoceros), the Asiatic palm weevil 

 (Rhychophorus ferrugineus), and some other weevils, discussing their 

 life-history, the damage they do, and remedial measures. 



Sensory Organs on Wings. f — G-. Noe calls attention to the presence 

 of distinct sensory -structures on the convex surface of the nervures 

 of the wings in species of the Dipterous genera Mycterotypus, Cidex, 

 ■Chironomus, Calliphora, etc. 



New York Mosquitos.§ — E. Porter Felt discusses the diversities in 

 the structure and habits of adult and larval mosquitos in the New York 

 State. He indicates the theoretical interest and practical importance of 

 these diversities, and how much still requires to be done in regard to the 

 group. The features of numerous species are beautifully illustrated. 



Blood -Sucking Muscidae. || — K. Griinberg describes Glossinella 

 schillingsi g. et sp. n., from German East Africa, and discusses the 

 genera Stomoxys, Hamiatobia, Lyperosia, Beccarimyia, Olossina, bringing 

 together in a convenient form the scattered diagnoses. He also reports 

 on some new species of Stomoxys from Africa, and on the distribution of 

 the species of tsetse fly. 



Effects of Parasites on Oocytes of Queen Termite. IT — G. Brunelli 

 calls attention to the interesting fact that in queens of Termes lucifugus 

 and Calotermes flavicollis infected with Protozoon parasites in the intes- 

 tine, there is a correlated destruction of oocytes — a sort of indirect 

 parasitic castration. 



Wing-Structure in Cicads.** — O. E. Imhof discusses the details of 

 the wings — ribs, joints, folds, etc. — and their insertions on the thorax.
