19 2 Mosquitoes 



Dr. Smith thinks the individual life to be about three 

 months. The eggs would indicate that hibernation 

 takes place in that stage. The adults were always 

 found with canadensis, they had the same flight habits 

 and bit readily, not, however, being noticeably greedy. 

 They are never found outside of the woods, and the 

 infrequency of their occurrence makes them of little 

 economic importance. 



The occurrence of a number of species of which 

 little is known and which are not, as a rule, common 

 or troublesome, is as follows. 



In the south we have McgarJiinus rutilus and scp- 

 tentrionalis (Fig. 7, page 37), gigantic and gorgeous 

 mosquitoes, easily distinguished by their size and 

 curved probosces. The latter was taken in Louisiana, 

 near New Orleans, but not at Baton Rouge. M. 

 rutilus occurs in Florida, M. scptentrionalis from Ohio 

 south to the Gulf and westward to Missouri. Other 

 southern forms are Lcpidosia cyanescens, ranging from 

 southern Alabama to Texas ; O. bracteatns in the 

 southern portion of the United States east of Texas ; 

 O. mitchellcB in Florida, where also occurs Deinocerites 

 cancer, which has a most curious larva that lives in 

 the crab holes ; GrabJiamia signipennis in Texas. In 

 the north are found O.spenceri, north-western United 

 States and Canada; O. fictcJicri, and O. vittatus, 

 generally over the west ; C. tarsalis, Illinois westward 

 to the Pacific ; O. cinereoborealis, a wood species, as 

 are also lazarensis and inconspicuus, the latter being 

 a New Jersey species, the former ranging over the 

 eastern United States. O. impiger is found in the 

 eastern United States; Culicella dyari, from New
