144 THE CANADIAN ENTOMOLOGIST. 



except the enlarged basal joint of the fore legs, which is pitchy-fuscous. 

 Abdomen pale dirty brown ; the ventral ganglions very visible ; last ventral 

 segment dark brown, strong, ending in a bottle-shaped tube, somewhat 

 contracted before its round opening ; this tube is turned to the left side 

 and partly surrounded by a horny hook originating between the left ap- 

 pendage and the tube, on which it is laying somewhat in the shape of a 

 cornucopia. On the right side near the right appendage is a similar hook, 

 but larger and more dorsal, as long as the tube ; the basal half of it forms 

 a spoon-shaped lobe, the apical third is analogous to the left hook, the tip 

 bent up sharply ; before tip inside a kind of blunt tooth ; appendages 

 long, the apical joint as long as the basal ; the left appendage has the 

 basal joint perhaps a little thicker at base ; there is very little asymmetry 

 if at all, in the appendages. 



Wings narrow, pale fuliginous ; radius dark fuscous, venation fus- 

 cescent; sector bifurcated, four transversals between its upper branch 

 and the radius ; three costals in the apical half of wing, the last one best 

 defined ; there are five longitudinal whitish bands in the wing. 



Hab. One specimen from Honolulu. Mr. Hoffman, who owns a very 

 large botanical garden there, containing many species of palms and 

 orchids, had given orders to collect insects in his greenhouses. Among 

 this miscellaneous lot was one Oligotoma. McLachlan's description is 

 made from three carded specimens from the Hawaiian Islands ; though 

 it is diflicult to compare dry and alcoholic specimens, it seems to be very 

 probable that my specimen is O. instilaris. The only difierence of 

 importance, the shape of the prothorax, may be the effect of exsiccation. 

 A specimen from Antigua, in McLachlan's collection, is so similar to 

 O. iiisularis that he hesitates to separate it therefrom. Perhaps the 

 latter may be 0. Cubana. Finally, a richer material will have to decide 

 if O. Cubana is really different from O. insularis. The only specimen of 

 the latter species before me is more delicate, the wings narrower, the 

 colors much darker, the prothorax larger and different. It could have 

 been imported into the Sandwich Islands with plants, just as other 

 American insects.
