15<5 THE CANADIAX ENTOMOLOGIST. 



lliis, in some respects anomalous Aphis, was detected feeding on a 

 tender shoot of the willow oak, Qjiercus phellos, variety laiwifolice. No 

 winged specimens could be found. 



The broad head, slightly pubescent abdomen and other characters 

 would seem to exclude it from the genus LacJuius. 1 have therefore 

 placed it provisionally in Phyllaphis genus, to which it seems most closely 

 allied. 



DESCRIPTION OF A NEW SPECIES OF TROCHILIUM. 



BY HERMAN STRPXKER. 



Trochilium Grande, n. sp. — General appearance of T. Ccto 

 (Meliltia Cncm-bitce Harr.) but very much larger, expanding i^ inches. 



Antennae blackish. Palpi reddish orange. Head white in front, dark 

 lustrous greenish gray on top. Collar red. Tliorax above dark greenish 

 same as top of head. Abdomen red, each segment outwardly edged with 

 black. Beneath whole body reddish orange ; on the abdomen a row of 

 black ventral spots. Posterior legs heavily clothed with red hair, accom- 

 panied by a narrow ridge of black, above, towards the abdomen ; tibial 

 spurs black edged with white hair inwardly. Fore and middle legs red, 

 tarsi black and white ringed. 



Primaries. Upper surface same dark silky gray as back of thorax. 

 Secondaries transparent, broadly fringed on exterior edge with same color 

 as primaries ; some orange hairs at abdominal margin and base of wing. 



Under surface. Primaries shining orange red shading somewhat into 

 gray towards exterior margin. Fringe gray. Secondaries as on up])er 

 surface, but with some red scales along costa. q 



Hab. Texas. 



Allied to Destnopoda Boi?ibifonnis, Feld., Trochilium Astarte^ Westw., 

 but still more closely to our smaller indigenous species T. Ctto, above 

 alluded to, and to a species from Mexico lately described by Hy. Edwards 

 as Meliltia Gloriosa ; this latter differs from all those mentioned in having 

 opaque hind wings. 



As the description of Hiibner's genus Melittia, in which the Americans 

 place Ceto, is much too vague and uncertain (" The fore wings partlv, the 

 hind wings entirely transparent; the feet very thickly haired.") I have pre- 

 ferred to adopt Prof Westwood's infinitely better determined genus 

 Trochilium.
