HYMENOPTERA. — BEMBECIDE. 201 
nomy of very few of the species has been hitherto observed. Many 
of the species of the typical genus Larra Jad. exhibit a splendid 
sericeous coating, and are further distinguished by the two upper 
ocelli, which are large, and tortuous in their form (Savigny, Egype). 
The species of the allied genus Tachytes Panz. (Lyrops Iilig.) are 
_ generally captured in sand-banks. LL. pompiliformis is stated by Mr. 
Shuckard to provision its nest with the larve of a small Lepidopterous 
insect. The rare British species Miscophus bicolor Jur. (hitherto, I 
believe, taken by no other collector but myself) also frequents sand 
banks, in which I have observed it burrowing (see Trans. Ent. Soc. 
vol. i. p. 203.), although its legs are almost destitute of spines or 
cilia (jig. 80. 6.). The beautiful and equally rare Dinetus pictus 
Jur. is remarkable for the curious convoluted antennz of the males. 
The exotic genus Palarus is at once distinguished by the constricted 
segments of its abdomen. Savigny has figured several very singular 
allied insects (Egypte. Hyménopt. pl. 11.), in one of which the maxil- 
lary palpi are quite anomalous (jig. 82. 10.), the fifth joint being 
greatly dilated, and terminated by two large oval masses attached to 
the joint by a short peduncle. It may possibly be the effect of disease, 
as a figure of a palpus of the ordinary form (fig. 82. 11.) is added by 
Savigny. The mandibles in this species are very slender and entire, 
both externally and at the tip. 
The family Bemprcipm* (fig. 82. 19. Bembex rostrata) is also of 
small extent, corresponding with the genus Bembex of Fabricius, and 
chiefly distinguished by the structure of the mouth. The labrum is 
triangular and exserted; the head is transverse, the eyes extending 
to its posterior margin; the mandibles are acute, with a tooth on the 
inside ; the maxille have the terminal lobe well developed, being 
greatly elongated in the typical genus (jig. 82. 20.); the labium is 
also elongated, forming in Bembex a very long tongue (fig. 82. 21.),
