In the suctorial Butter- fl}', the lips, mandi- Insects may be divided into the masticating (as the Beetle) and the suctorial (as the Butterfly). In the former group, the oral apparatus consists of two pairs of horny jaws {inaJididles and vtaxill(i'), which work horizon- tally between an upper [labrum) and an under {lahiuin) lip. The maxillas and under lip carry sen- sitive jointed threads, or feelers {palpi). The front edge of the labium is commonly known as the tongue {ligula).''' In such a mouth, the mandibles are the most important parts; but in passing to the suctorial Insects, we find that the mandibles are secondary to the maxilla^ and la- Ijium, which are the o\\\y means Bee tribe, we have a transition the sucking Insects — the up-.
