CLASSIFICATION OF T LI 15 ASCAL APHID M, 



247 



Burm. Handb. 1001 (teste Hag en). — U. senex, Ramb. Ntfvrop. p. 357? 

 — A. 4-maculatus, Say, Long's Exped. ii. p. 305.) 

 Hab. Southern States ; West Indies. 



I have a series of examples from Texas which I consider to 

 belong to this species. In some of them there is a grey cloud- 

 ing in the apex of the hind wings. 



2. U. avunculus, Hagen. (Ascal. avunculus, Hag. N. Amer. Neurop. 

 p. 238.) 



Hab. Cuba. 



According to Hagen, very closely allied to hyalina. 



3. U. Macleayana, Guilding. (Ascal. Macleayanus, Guilding, Trans. 

 Linn. Sec. xiv. p. 140, tab. vii. fig. 11.) 



Hab. St. Vincent ( Guilding). 



Merged in TJ. hyalina by Hagen. Typical examples are in the 

 Oxford Museum (with larvae); and these appear to be distinct 

 from the Texan individuals that I consider to be hyalina ; they are 

 smaller, narrower-winged, and much less robust, though of the 

 same general form. The specimens from Jamaica placed under 

 the name by Walker are quite different, and are only forms of 

 his surinamensis {vide infra), wanting the apical clouding of the 

 hind wings. 



4. U. qua dri punctata, Burmeister. (Ascal. 4-punctatus, Burm. 

 Handb. ii. p. 1001 ; Hag. N. Amer. Neurop. p. 238. — A. 3-maculatus, 

 Lefebv. Guerin's Mag. 1842. — A. surinamensis, Walk. Cat. Brit. 

 Mus. Neurop. p. 439 (nec Fab. ??). — A. Macleayanus, Walk. op. cit. 

 p. 436 (nec Guild.?).) 



Hab. United States ; Jamaica ? ? 



Walker's surinamensis cannot be a form of linibata, as stated by 

 Hagen (N. Amer. Neurop. p. 239) — according to my ideas, 

 being far too large and broad- winged an insect ; but it is scarcely 

 possible that it can be identical with Burmeister' s k-punctatus. 



5. U. microcephala, Rambur. (U. microcephala, Ramb. Nevrop. 

 p. 359.) 



Hab. Havana; Brazil? 



I have examples indicated vaguely as from " Brazil," which 

 seem to agree with Bambur's description, the head being certainly 

 much smaller than in allied forms ; otherwise they are very close 

 to Bambur's type of his senex. 



6. U. cajennensis, Fabricius. (Ascal. cajennensis, Fab. Mant. Ins. 

 p. 250 ; Ent. Syst. ii. p. 96.) 



Hab. Cayenne (Fabricius).
