the type), the thorax is sparsely and finely punctured, a few coaise 

 punctures intermixed in the center of the disk, the eyes are reniform, 

 the scutellum small, the elytra about twice as large as in the 9 , and 

 the front tibiae armed ; 9 , the head is more coarsely sculptured, the 

 punctures being larger, thicker and more irregular, the antennae reach 

 not quite to the middle of the thorax (3.5 mm. in type), the thorax is 

 very coarsely and strongly punctured, especially on the anterior por- 

 tion of the disk, the eyes are longly oval, the scutellum large, the 

 elytra much smaller and more hairy than in the $, and the front tibiae 

 unarmed. 



Early stages: Exuvia of third larva hairless and unarmed, nymph 

 Calmost completely transformed), $, much as in imago but not chiti- 

 nized.

Geog. Dist., Gove Co., Kansas (2813 ft.), June, 1910, "para- 

 site in the nests of Anthophora occidentals," 17 specimens 

 (F. X. Williams). 



Types ( $ , 9 , nymph, larval skin) in the collection of the 

 University of Kansas; cotypes: eight in the collection of the 

 University of Kansas, six in the writer's collection. 



The variation in the size of the elytra, in the color and in 

 the dimensions of the specimens is considerable. They may 

 be told at a glance from the only other species in the genus 

 (minutipennis Rilev) by the marked difference in facies. The 

 following table will facilitate the more exact separation of the 

 two species : 



1. (2) Light ferrugineous, head slightly wider than pronotum, which 



is subparallel at sides minutipennis Riley. 



2. (i) Dark castaneous, head almost a third wider than pronotum, 



which is markedly arcuate at sides gigantea Wellm. 



The species just tabulated represent the extreme of degen- 

 eration from parasitic habits as it occurs among the Lyttidae, 

 and Mr. \Yilliams' discovery is most important, suggesting as 

 it does that further careful examination of bees' nests may 

 reveal other striking additions to our coleopterous fauna. 



PROFESSOR H. F. WICKHAM, Professor of Entomology at the State 

 University of Iowa at Iowa City, Iowa, wrote in November : "Although 

 entomology is entirely elective here, I have 100 students working at it."
