EIGHTH WEEK 



In this and the three succeeding weeks twelve species are to be de- 

 termined as nearly as may be with the available literature. This 

 twelve must include at least one of each of the following orders: Hy- 

 menoptera,Lepidoptera, Diptera, Coleoptera, Hemiptera and Orthofftera. 

 Make notes and drawings freely while making the determinations, and 

 note particularly the publications used and the results obtained. 



HYMENOPTERA. Cresson's Synopsis is the basis for determina- 

 tions in this order. Consult also manuscript synopses of particular 

 groups. For a reference to the described species compare Cresson's 

 Catalogue of the species of Hymenoptera. 



LEPIDOPTERA. Use Morris' Synopsis of Lepidoptera for the groups 

 represented therein. Consult Smith's List of Lepidoptera and also 

 manuscript synopses and lists. 



DIPTERA. Williston's Synopsis of Diptera. For the genera of 

 Orthorapha not in Williston see manuscript synopsis. For Cyclorapha 

 use Schiner's Fauna Austraica. For species consult Osten Sacken's 

 Catalogue of Diptera and manuscript additions. 



NEUROPTERA. Use Hagen's Synopsis of Neuroptera. 



COLEOPTERA. For genera use LeConte and Horn's Classification 

 of Coleoptera and for species compare Henshaw's Lists of Synopses and 

 his Checklist. 



HEMIPTERA AND PHYSOPODA. Use synopsis in Comstock's In- 

 troduction to Entomology and also manuscript synopses and lists. 

 Compare Uhler's Checklist of Heteroptera and manuscript list of Hom- 

 optera. 



ORTHOPTERA. Use synopsis in Comstock's Introduction to En- 

 tomology and manuscript synopses and lists. 



PSEUDONEUROPTERA. Use Hagen's Synopsis of Neuroptera. 



THRYSANURA. Use synopsis in Comstock's Introduction to En- 

 tomology. 



ELECTIVE WORK. Determination. 



The twelfth to sixteenth weeks may be partly or wholly used for 

 further determinations. It is recommended that the student devote him- 

 self to as small a group as possible. Three species should represent 

 each week's work.
