Key to species(2)
1. Abdomen acutely margined. Head prolonged behind the eyes. Sides of thorax posteriorly sinuate ... C. stenoides
Abdomen slightly if at all margined. Head very slightly prolonged behind the eyes. Sides of thorax not sinuate posteriorly 2
2. Pronotum not rugulose, finely granular between the punctures .... C. fuscipennis (=punctatus)
Pronotum distinctly and finely rugulose between the punctures ... 3
3. Tibiae testaceous (Rocky Mts. eastward) .... C. obscurus
Tibiae almost always piceous (sw. US & Middle America) ... C. mexicanus
New World, mostly Neotropical. In our area(2)(3):
C. fuscipennis (=punctatus) FL;
C. mexicanus TX-CA;
C. obscurus NB-MB-CO south to GA-MS-AR;
C. stenoides NC-FL-OK-TX
Often found in tubular flowers such as morning glory and bindweed (Convolvulaceae). Various species also found on corn, cotton, and Dianthus (Caryophyllaceae)
