fuscis, haucl bene determinatis, ad suturam conniventibus, 

 WW formantibus ; ultima valde dilatata : pedes longitudine 

 mediocres, femoribus paullo tumidis. (Corj). long. •2125 unc. 

 lat. -065 unc.) 



Inhabits North America. A single specimen, taken by Mr. E. 

 Doubleday at St. John's BlufF, in East Florida, is in the cabinet of 

 the Entomological Club. This little insect will not range with Calli- 

 dium, Clytus, Gracilia, Obriiun or Cartallum, as these genera are at 

 present constituted : I am therefore inclined to raise it to the rank of 

 a genus, and would propose calling it Phytori limum. 



Family. — Necydalid.e, Newman. 



In tliis family I would propose to include Necydalis of Linneus, 

 Stenopterus of lUiger, Odontocera, Acyphodcres, Tomopterus and 

 Colobus of Serville, Glaphyra, Sphecomorpha, Charis, Hesthesis and 

 Heliomanes of Newman, and many other small longicorns which 1 

 have never yet been able to examine. They are to be distinguished 

 by the possession of abbreviated elytra, which are either truncate and 

 quadrate, or attenuated and pointed at the apex. All the species of 

 which we have any knowledge when living, are very active and fly with 

 great ease, and always in the day-time, frequenting flowers and the 

 leaves of trees. It is certainly questionable whether a group possess- 

 ing but one structural character in common can be considered strictly 

 natural, but the convenience of so ob^dous a distinction is beyond dis- 

 pute. The genera may be arranged in the following order. 



Genus. — Glaphyra, Newman. 



Caput fere pronum, prothorace haud angustius ; antennae vix dimi- 

 dio corporis longiores, ll-articulatae, articulis ultra 6um brevioribus, 

 crassioribus : prothorax dorso complanatus, lateribus paullo convex- 

 us, nullo modo armatus : elytra valde abbreviata, apice rotundata, 

 nuUo modo metalas tegeitna : pedes mediocres, femoribus pedetentim 

 tumidis, tibiis paullo incrassatis, hirsutis, tarsis brevibus. 



Glaph. semiusta. Castanea: prothorax et elytra profunde puncta: 

 color castaneus, abdominis segmentis apicalibus nigen-imis. — 

 (Coi-p. long. \7b unc. lat. "0225 unc.) 



Inhabits North America. A single specimen, taken by Mr. Foster 

 at St. John's Bluff in East Florida, is in the cabinet of the Entomolo- 

 gical Club.
