ATTEMPTED DIVISION OF BRITISH INSECTS. 399 



maxillary and labial feelers fully developed and distinctly arti- 

 culate ; fore-wings ample ; hind-wings small ; lives underground 

 in immense societies, consisting of three kinds of individuals, 

 males, females, and abortive females ; the latter differ from the 

 two former in wanting wings, and in having the pro-, meso-, and 

 metathorax of nearly uniform development. Formica. {Pohj- 

 ergus, Odontomachus, Ponera), Myrmiea, (Eciton, Atta, Cryp- 

 tocerus). 



Natural Order. — Mutillites, Solitary Ants. 



Larva and pupa unknown. Imago, with antennae composed of 

 about thirteen joints, not elbowed, rather attenuated exteriorly ; 

 mandibles long, dentate at the apex ; maxillae obtuse ; labium 

 short, obtuse, its ligula not produced ; maxillary and labial 

 feelers fully developed and distinctly articulate ; ocelli indistinct 

 or wanting ; wings possessed by the males only ; females usually 

 with the pro-, meso-, and metathorax equally developed ; 

 abortive females none. Inhabits sandy situations, is solitary. 

 (Dorylus, Labidus, Apterogyna, Psammotherma,) Mutilla, Myr- 

 mosa, {Mi/rmecoda, Scleroderma,) Methoca. This and the pre- 

 ceding order require subdivision. 



Stirps. — Sphecina, Sand-wasps. 

 Natural Order. — Scholiites. 



Larva an elongate inactive maggot ; inhabits a burrow or hole made 

 in the sand by its parent, and feeds on the larvae or imagines of 

 other insects which she has provided for its sustenance. Pupa 

 changes in a silken cocoon spun by the larva at the bottom of its 

 domicile. Imago, with antennae composed of about thirteen 

 joints, very short, recurved, almost forming a ring; mandibles 

 short, strong, dentate; maxillae long, their feelers also long; labium 

 longer than in the Formicina ; its ligula trilobed ; ocelli three, 

 distinct ; wings alike in both sexes ; legs short, stout, spiny ; 

 female with a pungent sting. Solitary ; inhabits sandy districts, 

 settling occasionally on umbellate flowers ; feeds on insects. 

 Tiphia, {Myzina, Meria, Scholia.) 



Natural Order. — Sapygites. 



Larva and pupa supposed to be as in the preceding order. 

 Imago, with antennae composed of about thirteen joints, exteriorly 

 incrassated, particularly in the males, longer and more robust than 

 in the preceding order ; mandibles, labium, &e. nearly as in the
