6 INDEX TO MISSOURI ENTOMOLOGICAL REPORTS. 



geiit cultivator of the soil rather than to the naturalist, is set forth in 

 the following passage from the introduction to the first : 



Fully aware that I write for those who, as a rule, are unversed in entomology, I 

 have endeavored to treat of each insect with as little of the nomenclature of science 

 as is consistent with clearness of expression. Yet, as much that is of scientific inter- 

 est, such as descriptions of new species, must necessarily be inserted, I have had such 

 descriptions printed in a type of smaller size than the text, so that it can be skipped 

 jf desirable, at the time of reading, and easily referred to for comparison, with speci- 

 mens which one is desirous of naming,, I have also endeavored to illustrate, as far as 

 possible, the insects of which this report treats, believing that good illustration forms 

 the basis of successful teaching in a science with which the general husbandman is 

 not expected to be acquainted ; for the eye conveys to the mind, in an instant, what 

 the ear would fail to do in an hour. The practical man cares little to what genus or 

 family an insect belongs, so long as he can tell whether it be friend or foe. He must 

 become familiarized with the insects about him without having necessarily to over- 

 come scientific detail and technicality. 



I have made no effort at a systematic arrangement of the insects treated of. Indeed, 

 that were useless for the purpose in view ; but, in order that the reader may refer the 

 more readily to any particular insect which interests him, I have separated them into 

 three series Noxious, BENEFICIAL, and INXOXIOUS and attached a very full index. 

 For the benefit of those who are making a study of entomology, I have also given, 

 with each species, the Order and Family to which it belongs, in parenthesis under 

 each heading. 



So far as possible, I have used a common name for each insect, knowing that the 

 scientific name is remembered with greater difficulty, and is, consequently, distasteful 

 to many. But as popular names are very loosely applied, and the same name often 

 refers to different insects, in different localities, a great deal of confusion would ensue 

 without the scientific name, which is, therefore, invariably added, for the most part, 

 in parentheses, so that it may be skipped without interfering in any way with the sense 

 of the text. 



In order to add value to this general index, I have brought together 

 tables of contents of the nine volumes and given corrections and some 

 notes and additions. I have also reproduced the descriptions of new 

 species, and added a list of descriptions of adolescent states, of descrip- 

 tions of species not new, of illustrations by reports, of illustrations by 

 classification, and of food-plants. 



The Reports were independently paginated, and the separate copies 

 were often distributed before the Agricultural Report was off the press. 

 The date of publication and distribution is given for each in the tables 

 of contents. The nomenclature of the Reports is retained in this Bulle- 

 tin, the synonomy being indicated in the notes and additions and with 

 the reproduced descriptions. The name of the author of the species 

 and not of the genus was always given as authority, and in the later 

 Reports I endeavored to indicate whether or not the insect was described 

 under the generic name which it bears, by adding the authority without 

 a comma when the specific name is coupled with the generic name un- 

 der which it was first published c . </., Plnjcita nebulo Walsh but placed 

 it in parentheses when a different generic name was used than that under 

 which the insect was first described c. #., Acrobasis nebulo (Walsh) 

 except where the whole name was already in parentheses when a comma
