6 RHYNCHITID^E. 



[LeConte. 



9 eyes less prominent, front wider, head broadly rounded behind the 

 eyes and more convex ; middle tibiae straight ; external apical tooth of 

 mandibles very prominent. 



Middle, Southern, and Western States to Texas. Very variable in color, 

 but with the legs usually yellow, rarely varied with fuscous.

 Nov. 188. 



Middle, Southern, and Western States, to Texas. Equally variable in 

 color, but the legs are almost always black, rarely varied with testaceous. 



Of twelve specimens before me all seem to be 9> an( i differ from those 

 of the preceding species only by having the head behind the eyes cylindri- 

 cal and not narrowed. It may possibly be a dimorphous form of Eu. 

 angustatus. 



4. Eu. puncticeps, n. sp. 



Of the same form as collaris, testaceous clothed with erect hairs. Beak 

 rather stouter less deeply sculptured, front obsoletely channeled, head 

 coarsely and sparsely punctured, cylindrical not narrowed behind. Pro- 

 thorax coarsely punctured, feebly channeled. Elytra with striae composed 

 of approximate punctures, interspaces wide flat, each with a row of very 

 small distant punctures. Antennae extending to the base of prothorax, 

 stouter than in the other species. Length 3.6 mm's ; .15 inch. 



Illinois, Mr. B. D. Walsh ; Georgia. I have seen but two 9 of t^ 8 

 species ; it is easily recognized by the stouter antennae, and more uni- 

 formly sculptured beak, which is free from the impressions and lines seen 

 in the two preceding species. 



5. Eu. sulcifrons Gyll., Sch. Cure, v, 343. 



I refer to this species, a ^ from Texas, sent by Mr. Belfrage. It is of 

 exactly the same form and sculpture as Eu. angustatus, but the eyes are 

 less prominent, more as in the 9 of that species, and there is a fine but dis- 

 tinct frontal channel ; the head is gradually and distinctly narrowed be- 

 hind the eyes. The color is testaceous, with a lateral blackish vitta on the 

 elytra gradually becoming broader behind ; an extension of this dark color 

 would give the appearance mentioned by Gyllenhal, in whose specimen 

 the elytra were black with a blue reflexion, and pale piceous towards the 

 base.
