584 NEUROPTERA. 



It is a rather large insect, the head and mouth-parts measur- 

 ing thirty-nine millimetres, the three thoracic rings twenty- 

 eight millimetres, and the part preserved of the right upper 

 wing forty-four millimetres, and of the right under Aving fifty- 

 one millimetres. The antenna? are long and thread-like, as in 

 Panorpa, and the venation of the wings are of the Neuropter- 

 ous type, while the elongated mouth-parts are Hemipterous in 

 appearance, though the labial palpi (Ae) are well developed, 

 being usually absent in the Hemiptera. It is the most puz- 

 zling form yet brought to light, and has been compared by 

 Dr. Dohrn to the fossil Archseopteryx of the Solenhofen slates, 

 referred by some natui'alists to the birds, and by others to the 

 reptiles. 



We have shown elsewhere* that the IVeuropterous families, 

 except the most typical, i.e.^ the Ephemeridm and Lihellu- 

 lidce, mimic every other suborder of insects. They are in 

 fact comprehensive or synthetic types, combining, as do all 

 decephalized, embiyonic forms, the structures of the other sub- 

 orders of insects, and thus presenting, in advance, features 

 which remind us of characters more fully wrought out in higher 

 and more compactly finished groups of insects. 



As regards the preservation of the dragon-flies, Mr. Uhler 

 states that "the large, brilliant green dragon-flies (Cordn- 

 lina), as well as the yellow, brown-striped Gomphina, having 

 the eyes Avide apart, will furnish new species in almost all parts 

 of the countr}'. In order to preserve specimens in the neatest 

 manner it is Avell to slip them immediately, when caught, into 

 paper bags of suitable size ; first taking care to laj back the 

 wings so that they will be applied together, to prevent mutila- 

 tion. These paper bags may be placed loosely in a box carried 

 for the purpose. They can thus be taken out at leisure, killed 

 by applying a camel's hair pencil, dipped in sulphuric ether, 

 chloroform, or benzine, to the under side of the bod}^, and then 

 have the Avings spread by placing them upon the setting 



to tlie Ortlioptera, aud -which serve to unite the two suborders more intimately 

 than ever. Indeed entomologists in the future may unite the Orthoptera and 

 Neuroptera (in the Linnajan sense) into a single siiborder equivalent to the Coleop- 

 tei"a or Ilymenoptera, and these two groups may stand as two subordinate divi- 

 sions just as the "Homoptera" aud "Hemiptera" are siibdivisions of the Lin- 

 njean group of Hemiptera.
