Trichoptera and be done with it. The objection that Comstock's Frenatte 

 incUides many Lepidoptera without a frenulum is somewhat paralleled 

 by the fact that some of Dr. Packard's Lepidoptera glossata (Fabricius's 

 term for the order) have no tongue. The difficulty of " combining " 

 these two systems lies in the fact that different organs are employed. Dr. 

 Packard's paper closes with a genealogical tree at which my old friend, 

 Mr. W. H. Edwards, if he is still standing on his rock and is not washed 

 away by Dyarian waves, will no doubt lift his hands in astonishment. 

 Dr. Packard has virtually abandoned the old Latreillean camp and joined 

 the ranks of the new school. 



In a far wider sense than as a correlator of contending systems, Mr. 

 Tutt merits respect for his untiring industry and his success in raising the 

 standard of scientific Lepidopterology in England ; I might almost say in 

 Europe, for the study itself has been in some danger of following the 

 objects of the study, into the useful hands of the dealers in insects. With 

 ever fresh enthusiasm and all the power of expressmg himself clearly, Mr. 

 Tutt combines both point and poetry, so that to read one of his discus- 

 sions on synonymy is a pleasant task. The student, whether objectively 

 of science, or subjectively of nature, cannot fail to be benefitted by Mr. 

 Tutt's writings.

Though nearly a twelve-month has gone by since the preceding Part 

 was noticed in our pages, we could well afford to wait with patience for 

 another issue, when our author rewards us with so much that is remark- 

 ably interesting, as well as valuable, regarding the life-histories of some 

 hitherto little known Butterflies. 



The first plate, which as usual is exquisitely drawn and coloured, 

 depicts the female of Parnassius Smijitheus, Doubl.-Hew., and both 

 sexes of the variety Hermodiir, Hy.-Edw., together with the egg, larva in 

 all its stages, chrysalis, last segments of the male butterfly, and many 

 highly magnified details. After giving a description of the various stages 

 of the insect, the author relates many most interesting facts regarding the 

 life and habits of the butterfly, which have taken expert observers in the
