lected in September by Mr. Armstrong. Rare in Iowa, abun- 

 dant in Kansas. 



Agra obi.ongopunctata Chevr. (Coleop. du Mexique, 8e 

 fascicule, 183). The first member of the Agrini reported 

 from the United States. Several specimens were beaten from 

 the thickest vine-covered tangles in the little tropical jungles 

 already described. Mr. Townsend had two specimens (taken 

 in June) on my arrival, and I continued to find it until late in 

 July. The insect presents a most remarkable appearance. 

 The head is impunctured, greatly elongate both before and 

 behind the eyes, much constricted at the neck, surface pol- 

 ished. Thorax slender, nearly conical, sides sinuate near front 

 and hind angles, lateral margin represented by a raised line: 

 the disk is marked with four rows of very deep often conflu- 

 ent punctures, intermixed with a few less evident ones. Below 

 the carina which I have considered to represent the lateral 

 margin is another row of serial punctures more distinct in 

 front, while beneath these will be seen a few scattered with- 

 out arrangement. Elytra narrow, broader behind the middle, 

 punctured in rows, the punctures large, deep, often elongate, 

 wider than the interstices. Fourth interspace with a fine 

 groove running nearly the entire length, margined interiorly 

 by a delicate carina. From near the tip of the sixth inter- 

 space a fine carina extends to the vicinity of the rounded su- 

 tural angle. Apex of elytra truncate and sinuate, the outer 

 angle nearly rectangular. Body beneath shining, prothorax 

 coarsely, meso- and metathorax rather finely punctured; met- 

 asternum grooved at middle, the groove wider behind. A 

 deep fovea just anterior to the middle coxae. Abdomen nearly 

 impunctured, at sides, each segment with a more or less dis- 

 tinct but indefinitely limited lateral impression, inside of which 

 is a group of rather fine punctures. Median line polished,, 

 shining. Last ventral deeply angularly emarginate, the lat- 

 eral impression deeper and with a more or less distinct fovea 

 at bottom. Length 12 to 14 mm. The description is drawn 

 up from two specimens both of which seem to be males. They 

 agree in color, being of an obscure bronze, prothorax slightly
