matin's series, however, shows both the normal and abnormal 

 forms (so called by Riley), or R. tenuipes Meinert and R. rileyt 

 Bergroth. Of the former he had both sexes in the winged form, 

 but of the latter only the males. 



Mr. Ashmead submitted some Mutillidae and called particular 

 attention to the difference between Sphaerophthalma and Pho- 

 topsis, the latter having been considered by Fox a synonym of 

 the former. Mr. Ashmead is of the opinion that one section of 

 the genus Photopsis is composed entirely of males of Cyphotes. 



Mr. Hubbard stated that he had ,found the brood cells of 

 Xyleborus xylographus, a species which burrows directly and 

 for a long distance into hickory wood. In the brood cell he 

 found a large colony of females and several males. In one corner 

 of the brood cell he found what is obviously a cemetery, con 

 taining dead larvae and adults, comparable to the cemeteries 

 which he had found in ants' nests. Mixed with the dead bodies 

 were thousands of eggs of a Tyroglyph mite. He further found 

 the body of the mother of the colony walled into a side burrow. 

 From this observation he inferred that the presence of dead 

 animal matter would interfere with the growth of the ambrosia 

 upon which the young Scolytids feed, and that we have here the 

 obvious beginning of a cultivation of ambrosia, a step towards 

 the condition of affairs which has recently excited so much 

 attention with certain ants. He considers that this indicates that 

 the Scolvtidac have a very high order of intelligence.
