are longer, those of the female shorter than the hody. Southern States. Judging 

 from a drawing, this isHebesiola nehulosa (Dej. Cat.) which Erichson (Schomburghk's 

 Reisen) considers as Saperda annulata Fabr. (Syst. El.)

Oculi emarginati.

Femora modice clavata. 



Ungues integri. 



Tarsi postici articulo 1"'" longiore. 



The body cylindrical, the thorax subquadrate, with a very slight spine on the 

 middle of the side, elytra rounded at tip. From Ezocenti'us (Muls.) this genus differs 

 by the structure of the antennae, and from DemipJiora (Serv.) by its clavate femora. 

 It is difficult to conceive what Serville means when he says " yeux entiers " in the 

 description of Desmiphora, Pogonocherus, and allied genera. 



1. E. TOMENTOSUS, castaneo-testaceus, fusco-pubescens, pilis erectis cinereis vestitus, tborace subtransverso, 



dense punctato, spina laterali distincta, elytris nitidis lineis transversis irregularibus ochreo-pubescentibus, 

 parce punctatis, punctis apice minoribus. Long. 'SI. 

 Desmipliora tomentosa Hald. 50. 



Middle and Southern States, the shining elytra, with the punctures much smaller 

 at the apex, easily distinguish this species. 



2. E. PAUPER, piceus, subtiliter sordide-pubescens, pilis erectis cinereis vestitus, thorace non transverso, 



densissime punctato, spina laterali minima, vix conspicua, elytris lineis transversis densius pubescentibus, 

 subseriatim-punctatis, punctis postice paulo minoribus. Long. '28. 



One specimen, Pennsylvania. 



3. E. VESTITUS, piceus, undique dense fusco-pubescens, pilis erectis cinereis vestitus, thorace confertissirae

Southern and Western States. Inasmuch as Haldeman has changed the name 

 neither of this nor the other Saperda vestita (Say,) but has placed them in different 

 genera, I continue the names adopted by him ; but I cannot help observing, that the 

 precedent is a very bad one, and that the careless use of the same name, by the same 

 individual, for two different objects, should always be followed by the change of the 

 name of the latter of them.
