268 ENTOMOLOGICAL NEWS. [June, '15 



35 mm. x 19 mm. to 60 mm. x 28 mm. ; females from 35 mm. 

 x 18 mm. to 50 mm. x 25 mm., while one female, almost a freak 

 in size, attained to 52 mm. x 27 mm. 



As to the Cicada Killer, Sphecius speciosus, I have seen it 

 climbing a telegraph pole, with its heavy burden of Cicada 

 marginata, that it might glide on a stage of its nestward jour- 

 ney ; I have seen by a roadside its inch-wide hole in the ground ; 

 I have seen it in early July with the male of Sphaerophthahna 

 occidentalis feeding at the gum of acorn buds ; I have seen it 

 later at wet spots on trunks of oaks as also at tityus scratch- 

 ings on ash limbs and, like hornets and some Lepidoptera, it 

 may feast on the dropped fruit of persimmon. 



A Wasp Resembling a Bee (Hym.). 

 By T. D. A. COCKERELL, Boulder, Colorado. 



All entomologists have heard of the remarkable resemblances 

 between certain butterflies of quite different families, but it is 

 not so well known that in Australia the aculeate hymenoptera 

 present some astonishing examples of "mimicry." A new 

 example, now before me. is found in a small wasp of the genus 

 Miscothyris, from Gilgai, New South Wales, December, 1911 

 (W. W. Froggatt 211), which in appearance and markings 

 almost perfectly resembles certain bees, more particularly 

 Euryglossa geminata Ckll., both being black, with the same 

 general arrangement of yellow markings on the scutellum, post- 

 scutellum, second abdominal segment, &c. The Miscothyris 

 appears to represent a color-variety of M. lucidulus Turner. 



Miscothyris lucidulus mimeticus n. race. 



$ . Like M. lucidulus, but flagellum ferruginous beneath ; upper 

 border of prothorax (except laterally), spot on tubercles, large mark 

 behind them, as well as scutellum and postscutellum, clypeus, lateral 

 face marks, triangular supraclypeal mark, scape (except a black mark 

 behind), and spot on each side of second abdominal segment, all bright 

 chrome yellow; anterior tibiae with a broad yellow band in front. 



M. lucidulus was described only from the female ; it is possi- 

 ble that the differences found in the present insect are sexual, 

 but they probably indicate a local race. Two specimens are 

 before me. The type is in my collection ; it will, however, 

 eventually rest in some large museum.
