7i8 REPORT OF NEW JERSEY STATE MUSEUM. 



A. sylvicola Gross. Larvae were taken at Paterson in May, at New 

 Brunswick May and June. Adults were taken also at Westville and 

 Mount Holly, specimens occurring near New Brunswick until VII, 28. 

 This is rather a rare species, breeding only in pools in dense wood- 

 land, whose shelter the adults never leave. There is only a single 

 spring brood, the late captures representing straggling survivors. 

 This species was at first identified with "squamiger," which later 

 proved to be different in habits and early stages. 

 A. niveitarsis Coq. Larvae were found near Paterson, V, 9, 14, in a 

 rocky, mountain pool, and the adults bred from them are the types 

 of the species, no other examples of which have been since taken. 

 A. cantator Coq. Also a salt marsh breeder, occurring along the entire 

 coast line, but much more abundant in the more northern ranges. 

 It replaces "sollicitans" north of Barnegat Bay as the early spring 

 form, and from larvse which hatch in March or April the first brood 

 comes early in May. After mid-summer it is much less numerous 

 and generally replaced by "sollicitans." It has the same egg-laying 

 and migrating habits as the latter species, and like it breeds until 

 the meadows are frozen — larvae being quite generally found under 

 the ice when the pools freeze in early winter. 

 A. subcantans Felt. Occurs throughout the northern parts of the State 

 in woodland pools. There is only a single spring brood, larvse ap- 

 pearing in March and maturing in early May; but the adults linger 

 until mid-summer. Larvae have been actually found at or near 

 Elizabeth, Newark, Arlington, Cranford, Millburn, Morristown and 

 in the Great Piece Meadows. This species was at first believed to 

 be identical with the European "cantans," but has been proved 

 distinct by careful study. 

 A. abfitchii Felt. Has the same range as the preceding and much the 

 same habits. It has been found a little further south, at New Bruns- 

 wick, and the adults occurred as far north as Lake Hopatcong and 

 Swartswood Lake. Mr. Grossbeck notes that, for breeding, both this 

 and the previous species "select swampy woodland areas or hilly 

 regions scattered over with large pools — small isolated pools being 

 rarely inhabited by them." The adults are hard biters, but do not 

 leave the woodland. This species was described by Mr. Grossbeck 

 as "siphonalis" at about the same time that Dr. Felt described his 

 species, but Dr. Felt's description was first published. 

 A. fitch ii Felt. Very much like the preceding in appearance and proba- 

 bly in habit; but rare in New Jersey. Mr. Brakeley has taken larvae 

 at Lahaway and Mr. Grossbeck in the Great Piece Meadows, both 

 in April. 

 A. sylvestris Theob. Occurs throughout the State and throughout the 

 summer, sometimes in considerable numbers; but rarely attempts to 

 bite and does not enter houses. Larvae appear in woodland pools 

 early in April, but later occur in more open places — anything from 

 a lot or even a clean gutter-pool to an overgrown swamp area serving 

 to develop them.
