MASARIS. INSECTS. 355 



Gen. MASAIIIS, Lat. Fab. 



Females with a sting ; eyes notched ; upper wings folded lon- 

 gitudinally in repose ; abdomen appearing sessile, elongated ; 

 antennae as long as the head and thorax, of eight joints, of 

 which the last is clavate. 



M. vespiformis, Fab. Antennae in the male long ; labrum triangu- 

 lar, longer than broad ; mandibles with four distinct teeth ; max- 

 illary palpi of four joints ; abdomen long and semicylindrical. In- 

 habits Africa. Lat. Gen. iv. 144. 



FAMILY VI. MELLIFERA, Lat. 



All the individuals with extended wings ; first joint of the pos- 

 terior tarsi large, compressed, square or triangular, and ge- 

 nerally furnished with a tuft of hairs proper for collecting the 

 pollen of flowers ; jaws and lip generally long and narrow, 

 forming a proboscis ; chin elongated, and supported on a move- 

 able pedicle ; labium in the greater number lanceolate or fili- 

 form, long and hairy. 



The larva; of the insects of this family are fed with the pollen of flowers and honey* 

 Many live in societies, composed of three kinds of individuals, as in the preceding 

 family, some of these temporary and others persistent. In the last of these the neu- 

 ters labour for the whole. 



TRIBE I. ANDREW ET^E, Lat. 



Intermediate division of the labium sometimes widened in a 

 heart-form, sometimes lanceolate, and in both cases shorter 

 than the sheath or chin, almost straight, or simply folded up- 

 wards ; jaws and lip long, forming a kind of proboscis bent 

 downwards. 



The insects of this tribe are solitary, and each species consists of but two kinds 

 of individuals. They collect the pollen of flowers by means of the hairs on their feet 



I. Intermediate division of the labium nearly heart-shaped. 



Gen. HYLJEUS, COLLETES. 

 IT. Intermediate division of the labium lanceolate, but rarely almost linear 



1 . Intermediate division of the labium folded upwards in repose. 



Gen. DASYPODA, ANDRENA, 



2. Intermediate division of the labium almost straight, advanced or bent inferiorly ; 

 three complete cubital cells. 



Gen. SPHECODES, HALICTUS, NOMIA. 



Gen. ANDRENA, Fab. Lat. Apis, Lin. Melitta, Kirby. 

 Intermediate division of the labium lanceolate, folded upwards 

 in repose ; jaws simply bent near their extremity ; all the 

 legs longer than the first joint of the tarsi ; three cubital are- 

 olae in the wings of the greater number, of which the second 

 and third receive a recurrent nerve ; body oblong and hairy ; 

 abdomen depressed.
