CLASvSIFICATION" OF THE ASCALAPHID^B. 247 



Burtn. Handb. 1001 {teste Hagen). — U. senex, Ramb. N6}rop. 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. Maclenyanus, Guilding, Trans. 

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

 Hab. St. Vincent (Guilding). 



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

 Oxford Museum (with larvse); 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. Tlie 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. auADKipuNCTATA, Burmeistcr. (Ascal. 4-punctatus, Burm. 



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



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



Mus, Neurop. p. 439 {nee Fab. ? ?). — A. Macleayanus, Walk. op. cit. 



p. 436 (nee Guild.-?).) 

 Hab. United States ; Jamaica ? ? 



Walker's surinamensis cannot be a form of limhafa, 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 4i-puncfafus. 



v/5. U. MiCROCBPHALA, Rumbur. (U. microcephala, Ramb. N4vrop, 

 p. 359.) 

 Hab. Havana; Brazil? 



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

 seem to agree with Kambur's desci'iption, the head being certainly 

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

 to E-ambur's type of his senex. 



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



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

 Hab. Cayenne (Fabricius).
