II. ORTHOPTERA FROM AFRICA, BEING A REPORT UPON SOME SALTATORIA MAINLY FROM CAMEROON CONTAINED IN THE CARNEGIE MUSEUM. By Lawrence Bruner. The present article is based on two major and two or three minor collections and odd specimens of orthopteroid insects which have come into the possession of the Carnegie Museum during the past four or five years. There are, all told, three hundred and eighty-two specimens.* The species are divided among the suborders as follows: Locnstoidea, fortj-eight; Achetoidea, sixteen; and Tcttigonoidea, forty-one; or approximately one hundred and five. Nine of these species appear to be new, and are thus characterized in this paper, while "a few of the Achetoidea have been reserved for further study. While the Orthoptera, as well as several other groups of insects, occurring in the general region, from which most of the material now being studied has come, have been quite extensively collected and worked over by entomologists, so far as certain isolated localities are concerned, no doubt there remain many other species, both common and rare, to be added. In fact, it is the opinion of the writer that tropical Africa as a whole is practically terra incognita, so far as its insect-fauna is concerned. Family TETRIGID.^. The grouse-locusts comprise a very interesting group, and are widely distributed over the surface of the earth. Of course they are most numerously represented in the warmer and more humid regions, where they abound in forests, jungles, swamps, or mountain slopes; in open * Note: It is proper to observe that not all of the representatives of certain of the commoner species of African Saltatorial Orthoptera were sent to Dr. Bruner, at the time the insects were submitted to him for study. In some cases where the species was represented by scores of specimens it was thought hardly worth while to burden him with the care of all of them. — VV. J. Holland. 92
