mologists should take a more lively interest in Philippine insects. 

 The fauna is interesting and must really be extensive, though as yet 

 imperfectly known. A good preliminary catalogue was published in 

 1895 by Fr. Casto de Elera, entitled " Catalogo sistematico de toda 

 la fauna de Filipinas, conocida hasta el presente," printed at the 

 press of the College of Saint Thomas in Manila. It is somewhat 

 marred, from our point of view, by the inclusion of the names of 

 sundry exotic insects which happened to be in the collection of the 

 College of St. Thomas. This is explained in the preface ; but one 

 gets an exaggerated idea of the number of Philippine insects known, 

 if this matter is not kept in mind. We mention this book particu- 

 larly, as it is not generally known in America, and will be the start- 

 ing point of our future lists. The author enumerates the following 

 number of species of Arthropods : 



Class I, HEXAPODA. 



Order Hymenoptera 68, Ashmead gives 183. 



Order Coleoptera i,573 



Order Siphonaptera i 



Order Diptera 272 



Order Lepidoptera 793, Semper gives 1,626. 



Order Neuroptera 104 



Order Hemiptera 624 



Order Orthoptera 287 



Order Corrodentia 15 



Class II, MYRIAPODA 21 



Class III, ARACHNIDA 79 



Class IV, CRUSTACEA 176 



In the Lepidoptera, the butterflies listed are mainly Philippine 

 species, but a considerable proportion of the moths, 55 out of 174 

 listed, are exotic species which will never naturally occur in the 

 Philippines. The butterflies follow largely Semper's work,* but in 

 the moths this was not then published. Semper gives 907 moths as 

 against Casto de Elera' s 119, a very gratifying advance. 



With this number we have adopted the plan of classifying the ar- 

 ticles according to the classes and orders of the Arthropods, grouping 

 them under the appropriate headings. Our readers can now tell at a 

 glance whether the number contains anything in their especial fields.
