UIPTBRA. 385 



Insect. Eur., VI, 25, and is entirely blind. Its thorax is divided 

 into two transversal portions. The under part of the last joint 

 of the tarsi is furnished with a transverse range of spines form- 

 ing a comb. Long before this, Reaumer had observed an ana- 

 logous parasitical animal (if it be not the same), provided with 

 a proboscis, on the Bee. He has figured it in his Memoirs, V, 

 pi. xxxviii, fig. 1 — 4. 



The head of the others Pupipara — Phthiromyies, Lat. — is very 

 small or almost Avanting. It forms a minute, vertical body near the 

 anterior and dorsal extremity of the thorax. 



They constitute the genus 



Mycteribia, Lat. — Phthiridium, Herm. 



These Insects have neither wings nor halteres, and resemble spi- 

 ders still more than the preceding ones. They live on Bats. Lin- 

 naeus arranged one species, and the only one he knew, with the Pedi- 

 culi *
