of Lipura ; thorax particularly long ; antennae about as long as the head, 

 the three proximal joints about equal, the terminal nearly as long as the 

 others together ; legs short ; the claws without teeth, the inferior claw not 

 dilated at the base ; elater not reaching the vertical tube, the dentes twice 

 as long as the manubrium and very slender, the manubrium reaching a 

 little beyond the abdomen ; mucrones with two teeth, the terminal hooked, 

 the secpnd longer and vertical. 



Found in moss in the woods, Orono, Me., April, 1899. by F. L. Harvey- 



Remarks. — This species reminds one of /. nivalis and albella 

 Packard, but it cannot be either. 



It differs from /. nivalis in having the first tooth of the mu- 

 crone curved, dentes twice as long as manubrium instead of 

 shghtly longer, and the mantibrium extending beyond the 

 body ; there is no tooth on the inner margin of the superior 

 claw. 



It differs from /. albella Pack, in not having eye patches, the 

 lower claw is lanceolate and not dilated at the base and the 

 mucrones have only two teeth. 



If our diagnosis is correct, this .species would, following Mac 

 Gillivray, be related to /. parva Mac G., from which it differs 

 in color and in having the claw not dilated in the middle. (The 

 second and third antennal segments are diluted at the apex as in 

 this species. )

CoELioxvs 8-DENTATA AND ITS HOST. — Although it has been long 

 known that the beegenus Coelioxys is parasitic on bees of the genus 

 Afegachile, yet none of the many American species have been hitherto 

 bred from the cells of the latter, our knowledge of the parasites having 

 come from observations on European species. During the past Summer 

 I received from Dr. Henry C. McCook several cells of the leaf-cutting 

 bee, Megachile mevdica Cresson, from which there emerged in due time 

 four female host-bees, and one female specimen of Coelioxys octodentata
