230 THE CANADIAN ENTOMOLOGIST. 



SO well known that it will scarcely be contended that I have mistaken the 

 insect. I give in parallel columns the generic diagnosis of each : 



SCOLECOCAMPA. EUCALYPTERA. 



Form robust, strong ; eyes naked: Form slender, slight ; eyes naked ; 



tibiae unarmed ; legs moderate, tibiae unarmed ; legs long, slender, 



strong, densely clothed with long closely scaled, anterior coxae unus- 



hair, forming tufts in the ^ . ually large. 



Tongue moderate, spiral ; front Tongue rudimentary, obsolete ; 

 not globose, with a pointed tuft di- front globose, with a pointed tuft 

 rected downward; palpi straight, directed upward; palpi oblique, 

 projecting far beyond the head, moderately exceeding the head, 

 rather roughly clothed, the second closely scaled except at tip of 

 joint longest, much enlarged and second joint, where a tuft of scales 

 more heavily clothed at tip, the ter- creates an apparent enlargement ; 

 minal joint drooping ; the whole, terminal joint, straight, the whole 

 with the frontal tuft, forming a forming a pointed snout, but pro- 

 pointed snout. jecting upward as well as forward. 



The species bipuncta has a very close resemblance, structurally and 

 superficially, with Dory odes acutaria, and, like it, is found in salt marshes. 

 I certainly cannot be accused of an overfondness for numerous genera, but 

 I do most firmly believe that Eucalyptera and Scolecocampa can not be 

 properly united. 



TO ENTOMOLOGISTS. 



Dr. H. A. Hagen, of Cambridge, Mass., is working on a monograph of 

 the Odonata, with special regard to their early stages. He will be thankful 

 to receive material from any collector who may have such, and will duly 

 acknowledge the same. Larvae or pupae (dry or in alcohol) will be valuable 

 to him, but he especially desires reared specimens of the insects, with such 

 notes as can be furnished of the earlier stages. We trust that all who can 

 will assist this distinguished author, who has done so much to aid others 

 in their entomological studies.
