NEURONIA. 249 



Museum, and a male and female in my own collection ; it is not 

 extant in the American collections (teste Osten Sacken), excepting 

 a unique female in that of Dr. Asa Fitch. The genus and species 

 is very singular and abnormal; perhaps the most remarkable of all 

 hitherto known Neuroptera. It certainly belongs to the Panor- 

 liina. 



Fam. X. FHRYGANINA. 



Body compressed; head exserted ; antennte long, setiform; 

 mouth connate, imperfect; labial palpi triarticulate ; pro- 

 thorax small;, wings longer than the body, transverse veins 

 rather few; posterior wings with the anal space large, 

 plicated (rarely absent); tarsi with 5 articulations. Larva 

 aquatic ; living in a tube-like case. 



I. Maxillary palpi differing in the sexes. 

 Sub-Family PHKYGANIDES. 



Spurs arranged 2, 4, 4; maxillary palpi in the males 4-jointed, 

 in the females 5-jointed ; three ocelli. 



NEURONIA Leach. 



Autennffi shorter than the wings ; wings rather broad, the apex 

 ovate, naked or almost naked. 



1. N. irrorata ! 



Phryganca irrorata Fab.! Sp. Ins. I, 389, 9; Mantis. Ins. I, 245, 10; En- 

 tom. Syst. II, 77, 11. — Neuroma concatenata Walk.! Catal. 8, 4. 



Rufous, shining; antennae blackish-piceous, the basal article ru- 

 fous within ; head and thorax clothed with white hair; feet luteous, 

 with black spines ; abdomen testaceous ; anterior wings whitish- 

 hyaline, densely, transversely irrorated with fuscous ; posterior 

 wings hyaline, the apex spotted with fuscous, the anterior margin 

 with a medial, larger, fuscous spot. (Female.) 



Length to tip of wings 18 millim. Alar expanse 32 millim. 



Bah. St. John's Bluff, East Florida; N. Red River (Kennicott). 



The insect does not altogether agree with the description of 

 Fabricius ; the type in the collection of Banks is to be examined 

 again.
