cies to Scaphidium, and, in fact, we consider that thisnew genus ought to be placed near that genus; the section Monomera must, therefore, be suppressed.(Having carefully examined these minute insects, I am able to state that their tarsi consist ofseveral joints.) THE SIXTH ORDER OF INSECTS,— ORTIIOPTERA, (Ulonata, Fabr.), (Dermaptera, De Geer),— United, for the most part, by Linnseus with the Hemiptera, and by Geoffrey with the Cole-optera, but forming a peculiar division, exhibit a body generally less firm than the last men-tioned order; soft, semimembranous, wing-covers much nerved, and not uniting at the suturein a straight line ; wings folded longitudinally, and often fan-like, divided by transversenervures; maxilla; always terminated by a corneous denticulated piece, and covered by agalea, corresponding with the outer division of the maxillte of the Coleoptera; and lastly, akind of tongue, or epiglottis. , • •» ©miTMOJPTEIROllTS IQ^SECTS .

This pupa and the larva resemble the perfectinsect in other respects, walking and feeding in the same manner. The mouth of the Orthoptera is composed of a labrum, two mandibles, two maxilljE, andfour palpi; those of the maxilla; have always five joints; the labial palpi, as in the Coleoptera,have only three. The mandibles are always very strong and horny; the tonguelet is con-stantly divided into two or four plates. The form of the antenna; varies less than in the Cole-optera, but they are generally composed of a much greater number of joints. Many, inaddition to the composite eyes, have two or three ocelli. The under-side of the basal jointsof the tarsi is often lieshy, or membranous; the basal joi
