second joint more slender and longer; third 

 joint subcylindrical, thicker at the base 

 than the apex, which is beset with minute 

 points. Labium subquadrate, broader at the 

 apex than the base. Labial palpi two- 

 jointed; first joint thick, cylindrical ; second 

 joint slender, rounded at apex. Body corne- 

 ous, highly polished, minutely punctured,

 tuberances curved upward. Over the body 

 are scattered a few light brown hairs. Color : 

 head and body testaceous. Body beneath 

 somewhat paler. Length about 25 mm.

. Pupa sordid white, elongated, with each of 

 the abdominal segments at the sides pro- 

 vided with a flat, quadrate process. Anal 

 segment with two rather long processes at 

 the extremity. Thorax subquadrate, sides 

 rounded. Head bent downward; wings 

 folded around the sides of the body. Length

A New Introduction to Entomology.* 

 — We have here a novel and suggestive book, 

 in which the interrelationships of insects 

 are worked out on independent lines. Neither 

 Professor Hyatt, a zoologist and paleon- 

 tologist of the very highest repute, nor 

 his associate Miss Arms, has ever before 

 claimed a hearing in the entomological world, 

 and they have approached the subject quite 

 untrammelled by tradition or authority, but 

 with experience as successful teachers and 

 thoroughly imbued with the principles which 

 guide modern science. It is not a text book 

 for scholars, but precisely what its title indi- 

 cates, a guide for teachers. It abounds with 

 novel suggestions, and is interspersed with 

 cautions of the utmost importance to teach-

ers. We have room here for only one pas- 

 sage, in which the limitations of the 

 Darwinian theory are enforced : 



"It is very important that teachers should 

 be cautious in allowing themselves the free 

 use of explanations which the doctrine of 

 Natural Selection seems to furnish. The 

 danger lies in the fascination of the logical 

 form presented by this doctrine, the ease 

 with which it seems to explain even the most 

 complicated relations of organic beings, and 

 the general although unfounded belief that it 

 is universally accepted and believed in by nat- 

 uralists. They will find . . . that this doctrine 

 is not used by any investigators in account- 

 ing for the origin of structures and their 

 modifications, and only to a limited extent 

 by those quoted above and others of the 

 same school [the so-called Neo-Lamarcki- 

 ans], in explaining the preservation of struc- 

 tures and modifications after they have been 

 originated by the action of physical and other 

 causes." 



A diagrammatic scheme for illustrating the 

 authors' views of the ph ylogeny of insects is 

 given on a preceding page of this number, 

 and we hope to print at an early date their 

 concluding general remarks, after a survey 

 of the whole field. 



Recent English publications. — The 

 fourth part of Buckton's Monograph of the 

 British Cicadae or Tettigidae, just issued, 

 completes the first of the two volumes of 

 which the work will be composed. The first 

 volume contains 41 plates and 211 pages of 

 text, 78 of the latter given up to the Intro- 

 duction. The remaining volume will treat 

 of the Jassides, Deltocephalides and Typhlo- 

 cybides of the classification adopted by him. 

 The fourth part of Moore's Lepidoptera 

 Indica is of less interest than the preceding. 

 The plates are still concerned with the Eu- 

 ploeinae but only with species of very sim- 

 ilar appearance having a dull brown ground 

 color, and of which the early stages are not 

 known. The modification of the hind mar-
