OF WASHINGTON. 405 



Howard, and Currie, active members, andKotinsky and Stetson, 

 visitors, present. 



Mr. Schwarz announced the death of Mr Hugo Soltau, a cor 

 responding member, and the further fact that by Mr. Soltau's will 

 his extensive collection of Coleoptera was bequeathed to the Na 

 tional Museum. 



Under the head of Exhibition of Specimens and Short Notes, Mr. 

 Ashmead showed an insect constituting a new genus of Bethyllidas 

 collected in Arizona by Mr. Schwarz. He also exhibited speci 

 mens of Dinoura (n. g.) auriventris n. sp. and D. cyanea n. 

 sp , which he had recently received from Mr. W. W. Froggatt, of 

 New South Wales, who had reared them from galls of Coccidsof 

 the Brachyscelid group. The insects belong to the family Cleo- 

 nymidae, all the species of which are parasitic upon coleopterous 

 larvae, so that these Dinouras are probably parasitic upon coleop 

 terous larvae, feeding in the Brachyscelid galls Mr. Schwarz 

 said that in Europe there is an Anthribid beetle belonging to the 

 genus Brachytarsus, which is a specific enemy ofLecanium scales ; 

 this genus is represented in Australia, and it is quite likely that 

 one of its species is the true host of the Dinoura. 



Mr. Marlatt showed photomicrographs of the anal plate of a 

 number of Diaspine scales. He showed both bromide prints and 

 platinotypes, the former being better. From the results so far 

 obtained, he believes that this will be an excellent method of il 

 lustrating or at least studying the obscure features of the anal 

 plates of Coccidse. 



Prof. Uhler exhibited specimens of certain Capsids, of which 

 the females only had been previously known. They were, Co- 

 quillettia insignis Uhler, C. amcena Uhler, Lobitodes inte 

 ger n. sp., Myrmicides polita n. sp. , and Orectoderus obliquus 

 n. sp., the males of these interesting forms having recently been 

 found by Mr. Elmer D. Ball in Colorado inhabiting ants' nests. 

 They are entirely different from the females, being wingless and 

 resembling ants so closely in general appearance that it is a plain 

 case of protective mimicry. In answer to a question, he said 

 that we have now about 2,000 species of the family Capsidae in 

 America north of Mexico, but that many of the forms extend well 

 down into South America. Mr. Ashmead spoke of the occur 

 rence of winged and wingless forms in Hymenoptera as gener-
