what the box contained pig iron or bars of lead. If the outer box is 

 strong there is no necessity for having the inner box very heavy. We 

 often get boxes here that show that the senders think that the more cot- 

 ton or excelsior they use between the boxes the greater their safety, and 

 if they had a steam hammer handy they would doubtless use that to get 

 more in. Very few people in this country seem to understand how to 

 properly pack insects for transportation. Our experience here has been 

 a sad one when we have loaned specimens for study. Our collection of 

 Sesiidce was destroyed in this way. HENRY SKINNER. 



Doings of Societies. 



A regular stated meeting of the Feldman Collecting Social 

 was held May i5th, at the residence of Mr. H. \V. \Vcn/.el, 

 1523 South 1 3th Street. President Mr. Charles W. Johnson 

 in the chair. 



Professor Smith again spoke about the mosquitoes which he 

 had previously mentioned and stated the following new facts : 

 All the specimens from the pitcher plants were sEdcs instead 

 of Culex as he first thought, and therefore all of the preceding 

 observations should be referred to sEdes. The two species 

 which he raised from his pitcher plants were /Ecdesfuscus and 

 A. sapphirinus. These are both new to New Jersey and have 

 only been found in the pitcher plants. He spoke of the larvae 

 of an sEdcs w r hich he examined, which had two anal flaps 

 showing a complete network of tracheae and which up to the 

 last stage were used in breathing. These larvae are able to 

 stay under water some time if the water is clear, but if it is 

 foul or muddy they must come to the top frequently, and if the 

 water becomes too foul the larvae die. He also spoke of 

 another lot of mosquito larvae he had received, which are only 

 found in spring holes. This one is different in all stages from 

 sEdcs, and he thought that they must have passed the winter 

 in the larva state. They are very lively, going to the bottom 

 at the least sign or shadow, this being a protection for them, as 

 they are yellow ; and when the)" go to the bottom it is difficult 

 to distinguish them from the mud which is there. They also 

 have to protect themselves from the larva of many other insects 

 which are found in these spring holes, while the larvae of 

 . I-'-des are protected by the pitcher plants in which very few
