A New Key to Paracalocoris with Descriptions of Eight New Species (Hemiptera, Miridæ).

In a previous paper (Ann. Ent. Soc. Am., xix, 1926, pp. 367–377) the writer gave a key for eighteen known Nearctic species of Paracalocoris Distant, also keys to the color varieties of P. externus H. S., scrupeus Say, and hawleyi Kngt. These keys to the color varieties are not repeated in the present article. Since the appearance of the above mentioned paper I have been able to recognize eight more new species and four new varieties, all of which are described in the present paper.. Two varieties described by Mr. McAtee are now raised to the rank of species, namely, Paracalocoris pallidulus McA. and P. castus McA. To the latter species belong the varieties colonus McA. and amiculus McA. I have also included a redescription and notes on the type of Paracalocoris adustus McAtee.

Descriptions of Seven New Paracalocoris with Keys to the Nearctic Species and Varieties (Hemiptera, Miridæ).

In an earlier volume of the Annals (Ann. Ent. Soc. Am., IX, 1916, pp. 366–390), Mr. W. L. McAtee published a key to the species and varieties of Paracalocoris Distant known at that time. During the intervening years the writer has accumulated material which includes seven hitherto unrecognized species which are described in the present paper. In addition, Capsus externus H. S. has been recognized from Florida, found to be a Paracalocoris , and a key to the color varieties published (Ent. News, xxxvii, 1926, pp. 258-262). A new key is now included for the eighteen known Nearctic species with keys to the varieties of those species which present striking color forms.
