358 EXTERNAL ANATOMY OF INSECTS. 



A Lobus Superior (the Upper-lobe). The outer lobe 

 of the Maxilla, incumbent on the inner one. In 

 the Predaceous Beetles this lobe is Inarticulate and 

 palpiform a ; and in Staphylimis olens, &c. it also 

 consists of two joints b . It is called the Galea by 

 Fabricius, in Orthoptera, &c. c 



B Lobus Inferior (the Lower-lobe). The inner lobe 

 of the Maxilla, covered by the outer one d . 



C Ungues (the Claws). One or more corneous sharp 

 claws which arm the lobes of the Maxilla e . In the 

 Predaceous Beetles there is only one terminating 

 the lower lobe, with which, in Cicindela, it articu- 

 lates ; in the Orthoptera and Libellidina there are 

 several. 



d Palpi Maxillares (the Maxillary Feelers). Two 

 jointed sensiferous organs, the use of which is not 

 clearly ascertained, emerging from an exterior la- 

 teral sinus of the Maxilla f . 



E Lingua (the Tongue). The organ situated within 

 the Labium or emerging from it, by which insects 

 in many cases collect their food and pass it down 

 to the Pharynx, situated at its roots above. It va- 

 ries considerably in different orders and tribes. In 

 the Orthoptera, Libellidina, &c. it is linguiform, 

 and quite distinct from the Labium S; it appears 

 also distinct in the lamellicorn beetles, &c. h In many
