thorace paulo latioribus, elongatis, subparalleli's, apice truncatis, pygidium ex 

 parte obtegente; unguiculi basi dentati. Long. 3.4 mm, (.14 inch). 



I have not seen anything corresponding with this. The locality is 

 in all probability erroneous. 



Mr. Reitter has since placed this in a new genus, Micruria, with 

 other species. 



E. Jiavescens Reitter, cited as having been collected in Chicago, 

 is from Chiapas, Mr. Salle having kindly examined the type in 

 Chevrolat's cabinet. 



I would here call the attention of those having occasion to use 

 Mr. Eeitter's descriptions, that what everybody else calls the base of 

 the thorax, he calls the apex. I have several times been confused by 

 this form of expression. 



l¥ITI»rL,A Fab. 



Antennae eleven-jointed, terminated by a suddenly formed club of 

 three joints, received in grooves beneath and in front of the eyes. 

 Labrum feebly emarginate. Maxillary palpi rather slender, the termi- 

 nal joint longest, subacute at tip. Prosternum dilated at tip, not 

 prolonged. Tarsi feebly dilated, the third joint feebly emarginate. 

 Abdominal segments 2 — 5 equal, the first very little longer. Males 

 "without accessory segment. 



This genus is allied closely to Epuraea but diflfers in the form of 

 the labrum, somewhat also in the length of the abdominal segments, 

 the rather less dilated tarsi and the sexual character. 



Three species are known in our fauna, briefly distinguished as 

 follows : 



Thorax coarsely and moderately densely punctured. 



Piceous, each elytron with discal rufous spot bipustnlata. 



Piceous, elytra uniform rufipes. 



Thorax sparsely and rather finely punctured. 



Elytra variable, often ornate with irregular paler spots ziczac. 



N. bipustulata Linn. — Oval, feebly convex, piceous, finely pubescent, 

 each elytron with rufous spot, legs rufous. Head coarsely punctured. Thorax 

 twice as wide at base as long, apex a little broader than the length, sides 

 moderately arcuate, margin moderately explanate, hind angles nearly rect- 

 angular, surface rather coarsely and moderately densely punctured. Elytra 

 longer than wide conjointly, rather sparsely and finely punctured, finely 

 pubescent. Pygidium densely punctured. Body beneath rather coarsely and 

 densely punctured. Length .16 — .20 inch; 5 — 6 mm. 



I am unable to detect any sexual differences, except that the last 

 ventral of male is a little less arcuate at apex. 



Originally desciibed from Europe, this species is now found every- 

 where in the Atlantic and Gulf States.
