the wide front, round eyes and minute antennae; all these taken 

 together, with the absence of all bristles, give this fly from a 

 front view a striking appearance, which can only be described as 

 *' frog-mouthed" or "frog-faced." 



In the shape of the head, this genus bears a considerable re- 

 semblance to Pteremis nivalis Haliday. The appearance of the 

 head from above is almost exactly the same, but the profile view 

 at once shows marked differences. 



The striking similarity in the maritime faunas of the south 

 Texas and Florida coasts, indicated by such forms as Macrancy- 

 lus< Oxacis, etc., among the Coleoptera, is thus seen to be borne 

 out also by the Diptera in Tabanus maritimus and psammophilus, 

 Lipochczta, etc. 



AN INSECT-CATCHING PLANT. 



By C. P. Gillette, Fort Collins, Colo. 



Any one who has attempted to collect the pretty blue flowers 

 from Lactuca pulchella must have been annoyed by the disagree- 

 able sticky exudation that covers the buds and stems near the 

 flowers, and probably the latter were soon thrown away in dis- 

 gust. This plant grows in great profusion along the railroad 

 track near the college grounds at Fort Collins, where it vies with 

 the entomological enthusiasts in the insect captures that it makes. 

 In a few minutes' time this afternoon I noticed the following 

 insects stuck fast, and for the most part dead, in the gummy 

 exudation above mentioned : 



Hymenoptera. Coccinella o-notata 

 Chalybion cceruleum sanguinea 



Ambyletes subrufus Nczmia episcopalis 



Myrmica lobicornis Scymnus sp. 



Formica fusca Trirhabda canadensis 



" integra Ellychnia corrusca 



Chrysis sp. Epicauta cinerea. 



Coleoptera. Odonata. 



Hippodamia convergens Lestes congener, 



sinuata 



There were also several species of Diptera and parasitic Hy- 

 menoptera as well as other species of ants that I did not know.
