160 ENTOMOLOGICAL NEWS. [May, 06 



joint fusco-testaceous ; a faint dark testaceous margin in front of the eye, 

 and a small spot anteriorly on the lateral lobe of the pronotum ; abdomen 

 above with gray spots in the usual pattern. Tegmina as long as head 

 and pronotum, rounded and slightly oblique at tip, longitudinal veins 

 prominent, cross-veins very feeble, lateral fields black, dorsal dark fus- 

 cous, a fine yellow line on vein at lateral margin of dorsal field, con- 

 tinued along apical margin of lateral field. Legs black, tibiae with 

 testaceous interrupted line on upper face, first tarsal joint dark testa- 

 ceous, black at tip ; spines of hind tibiaas testaceous at base and tip. 

 Cerci fuscous ; ovipositor short, black, nearly straight, distinctly denticu- 

 late, slightly exceeding cerci. Body 7.5 mm. long. Ovipositor 3.5 mm.; 

 hind femora, 5.5 mm.; tegmina, 2.6 mm. Type in coll. I. S. L. N. H. 



N. mexicanus Walk. C., i. 



N. carolinus Scudd. B., i ; H., i adult, i nymph. 



Gryllus americanus Blatchl. B., i ; C. (Coll. I. S. L. N. H.). From 

 what I have seen of this in Illinois, I should think it was clearly distinct. 

 Scudder's description of neglectus is right ior pennsyfvanicus, but not for 

 americanus. 



G. pennsylvanicus Burm. G., 9 ; B., Mar. 22 (Coll. I. S. L. N. H.). 

 Tfegmina longer than in Illinois specimens, in the females fully reaching 

 tip of abdomen. The B. specimen is long-winged. Of a large number 

 of nymphs from under boards at C. and B., the majority are probably 

 this species. 



(Ecanthus pint Beut. C. Coll. I. S. L. N. H.). This is the form near 

 4-punclatns, but with a transverse bar on the basal antennal joint in place 

 of the black dot, and assigned to the above species by Titus.*

There is perhaps no genus of North American Buprestidee 

 concerning which so little is positively known as the one here 

 named. Specimens are very rare in collections, our literature 

 is almost bare of allusions to them, and foreign literature of- 

 fers little more to the inquiring student. The genus was de- 

 scribed in 1865 by Marseul, who based it upon a single speci- 

 men, said to have been found in the Custom House at Paris, 

 emerging from a cedar of Lebanon (" Sortant d'un cedre du 

 Liban"), by M. Blondel.
