Chimarocephala vividifasciata( V> Q Geer).-- 3 $, 1 9 , were taken in Southern Colorado, June 11- 20, and in Northern New Mexico in August and September by Lieut. W. L. Carpenter. In the cloudiness of the wings, they agree best with Texau specimens as described in my Entomological Notes ( IV, 81). The generic name ( xiiapo^ Kt^ aTJj) is proposed for the species ( riridifasciata, brevipennis, cubeims, pacifica) placed by me ( loc. cit) under Tragoccphala ; the latter name, as M. Auguste Sall6 has pointed out to me, being pre- occupied in CoUoptera ( Dupont, 1834). 30. Pwloewa maculipennis Scudd.- 2 $, Southern Colorado, August to September, Lieut. W. L. Carpenter. 31 Arphia teporata, nov. sp.- This red- winged species is so nearly allied to A. frigida Scudd., of the high north, that it need only be compared with i t ; the upper extremity of the frontal costa of the head has no transverse carina setting off a pair of minute frontal foveolae; the fastigium of the vertex is very slightly narrower. The tegmina aire * The single species of Hippiscus mentioned below has the anterior lobe slightly impressed by a transverse sulcus, and in specimens dried after soaking in alcohol sucb an impression may be accidentally intensified. In Hadrotettix and Anconia there is a sjignc transverse sulcus near the middle of the anterior lobe, which in Anoonia, and sometimes in Hadrotettix, severs the cariua, but so slightly that T have placed the genera m tnis division. |
