HYMENOPTERA — MUTILLIDE. 2S 
The family MurtiLuip*, corresponding with the Linnean genus 
Mutilla (fig. 84. 13. Mutilla Europeag, 14. ditto 9 , 15—18. details 
of a large Mexican species, ? ), is composed of insects which are soli- 
tary in their habits, and of which there are only males and femalest, 
the latter of which are destitute of wings, with the segments of the 
thorax often soldered together; this sex is also destitute of ocelli, 
but they are provided with a powerful sting. The antenne are fili- 
form, or setaceous, the first and third joints being elongated; the 
first, however, is not equal to the one third of the entire length of 
these organs: the labrum is transverse and ciliated (fig. 84. 15.); the 
mandibles more or less notched (fig. 84. 16.) ; the maxillary palpi with 
the basal joint very small (fig. 84. 17.), the ligula not produced, and 
the labial palpi with the third joint more or less dilated (fig. 84. 18.). 
The body is often very much clothed with hair.{ The legs of the fe- 
males are very robust, with the tibiae and tarsi spined and ciliated, 
as in the other true Fossores. The sexes of the same species often 
vary very considerably in colour. They are generally found in hot 
sandy situations, the majority being exotic, very few occurring in our 
own country. The females run with very great quickness, secreting

+ Mr. Kirby speaks of neuter Mutille (Jntrod. to Entomol. ), but evidently incor- 
rectly, as the species, being solitary, are not provided with workers, or neuters, as they 
are termed. 
¢ This is a curious peculiarity, considering, at the same time, that the insects 
frequent the hottest localities.
