Order Hymenoptera. Fam. Sapygidas. 



Type of the Genus, Scolia 5-punctata Fah.

 Masaris Panz. — Scolia and Sirex Fab. — Vespa Geof. — Apis 

 Linn., Don. 



Antennce remote, inserted near the middle of the face, as long 

 as the head and thorax, clavate, especially in the males, and 

 13-jointed : 12-jointed in the females (1), basal joint the lon- 

 gest and stoutest, 2nd cup-shaped, 3rd slenderer, the remainder 

 gradually increasing in diameter and decreasing in length, the 

 1 1th joint being nearly quadrate, 1 2th short and ovate. 

 Labrum minute and concealed beneath the clypeus, forming a 

 tongue-shaped membranous lobe, coriaceous and ciliated at the 

 apex (2 /). 



Mandibles a little porrected, very hairy, slightly curved, with 3 

 strong teeth in both (3). 



MaxillcB rather long, terminated by an ovate incurved lobe, with 

 a notch on both sides near the apex, which forms an ovate lobe, 

 ciliated with strong bristles. Palpi much longer than the lobe, 

 slender and 6-jointed, the 2nd being the shortest and the 3rd 

 a little the longest (4) . 



Mentum long linear and slightly compressed. Labium composed 

 of 2 short pointed and pubescent lobes. Palpi bent back, com- 

 posed of 4 clavate joints of nearly equal length, the apical one 

 being fusiform (4). 

 Clypeus sinuated, and bidentate at the centre (2) .- head thick and or- 

 bicular, with an elevated line between the antenna : eyes lateral the 

 inner margin notched : ocelli 3 in triangle on the crown of the head. 

 Thorax elongate-ovate sloped and rounded behind, anterior margin 

 truncated and a little concave, collar forming a perfect band : scu- 

 tellum semiovate. Abdomen very much narrowed at the base, elon-

Sapyga is a remarkable Insect; its ample collar reminds us 

 of the Chrysidae, but in general aspect as well as in the shape 

 of the palpi and the form of the maxillary lobe, rounded and 

 reflected, we cannot fail from drawing a comparison with Hy- 

 laius (pi. 373) and the Andrenidae : it appears, however, to be 

 most related to the Mutillidaa and Scoliidae, and like them 

 the females have the power of stinging very acutely. 



Dr. Klug says these Insects frequent flowers in meadows
