Why did no larva pupate? The environment w:is not abnormal. 

 unless, perhaps, the food .supply was scanty. Perhaps the reison 

 lies iu the condilions of the " boruinjr ' These slow -gro win g, long- 

 lived, non-pupating wrigglers issued from eggs which were laid by 

 a virgin female The female issued from it.s pupal case and almost 

 immediately laid eggs. There was no other mosquito in the jar. 

 and there was certainly no mating. Perhaps parthenogenesis is not 

 unknown among mosquitoes. I do know that it is known. l>ul it'

Tin; ODONATA <>i TIII: ''BiOLOGiA CENTKALI- AMERICANA." - Hav- 

 ing recently been asked by Mr. F. D. G-odmau, of London, to under- 

 take the preparation of the part of this work relating to the Odonata, 

 and having accepted this offer. I desire to make this part as complete 

 as possible. As the " Biologia" aims to embrace all Mexican and 

 Central American specie?, whether include! in the joint collections 

 of Mr. Godmau and the late Mr. Silviu or not. 1 shall be great lv 

 indebted to any persons who will loan me Odomta (" drogonflies," 

 " darning-needles") from those countries for examination, the re- 

 sults of such study to be included in this work. In this connection 

 I will identify unnamed material for a very moderate return in 

 duplicates. As some recent collectors have distributed specimens 

 from that region quite widely, I suggest that any one willing to 

 aid me should write to me before sending the insects and let me 

 know the sources of their material, as, some time, labor and expense 

 may thereby be saved PHILIP P. CALVERT, Academy of Natural 

 Sciences, 19th and Race Streets, Philadelphia, Pa.
