apice acutas, paullo incurvse, haud dentate : maxillarum lacinia 

 obtusa, apice membranacea, intus pilosa ; galea tenuis, lacini^ vix 

 brevior ; maxipalpi 5-articulati articvilo 1°. 2".que brevissimis, 

 caeteris longioribus subsequalibus ; maxilla extus setis rigidis in- 

 structa ; labium membranaceum, exemplario meo rugosum quasi 

 desiccatum; labipalpi 3-articulati, articuli breves, subsequales : 

 prothorax transversus brevis, capita latior ; mesothorax fere qua- 

 dratum, metathorax latitudine brevior; abdomen breve, obesum, 

 hirsutum : alae amplae, longitudinaliter sinuatse, quasi plicatiles, 

 magnitudine subsequales : tarsi 5-articulati. 



Itho. fusca. Fiisca, setosa, subtus dilutior et paidlb Jlavescens ; 

 alee fuscescentes, nervurce longitudinales setis tectce, trmisversee 

 nisi supracostales nudce. (Corp. long. '55 unc. ; alar, dilat. 

 1*65 unc.) 



Entirely brown on the upper surface, but paler beneath, and in some 

 parts approaching to yellow : the wings brown and scarcely trans- 

 parent, ample, and somewhat folded longitudinally ; the nervures 

 are numerous, all the longitudinal ones, and also those above the 

 costa, are clothed with hairs, while the transverse nervures are 

 quite naked : in size and in habit, this insect is intermediate 

 between Chauliodes and Sialis.

TO THE EDITOR OF THE ENTOMOLOGICAL MAGAZINE. 



Sir, — As you were so good as to give my former specimen 

 a place in your Cabinet, I have ventured to send you two more ; 

 but should much prefer your not amputating the two last feet, 

 {joi7its of the tarsi f) as they constitute one of the characters 

 of my new species, or rather variety. Possibly, being so 

 much immersed in Latin, you were unable to make out the 

 English metre.
