14 FAUNA HAWAIIENSIS 



This species resembles D. hawaiiensis in general appearance, and in the form 

 of the petiole of the abdomen. The clypeus is very abruptly raised, and in a front 

 view of the face nearly the whole surface of the labrum is exposed, which for the 

 most part can only be seen in an apical view in the preceding species. Seen from 

 above the apical margin of the clypeus is angulate in the middle. The scutellum 

 has a median depression and the surface is in that region somewhat shining. 



Hab. Olaa, Hawaii (2000 ft.) ; i ? taken in June, 1895. 



(5) Deinomimesa haleakalae, sp. nov. 



D. konae simillima ; cT parte abdominis segmenti primi pedicellata supra compressa, 

 et carinata. cT. Long. 8 — 9 mm. 



Male very similar to that of D. hawaiiensis, but a larger insect. It may be 

 easily distinguished by the form of the petiole of the abdomen which is compressed 

 above from the sides into a median carina, whereas in D. haivaiiensis this part is 

 flattened above and has a raised line down the middle. The front tarsi outwardly 

 are more or less infuscate. 



Hab. Haleakala, Maui (4000 ft.); a few ^ (S taken in May, 1896. 



This species in the c/" approaches most nearly to the genus Nesomimesa, but the 

 distinct carination of the abdominal petiole, and the much more rugose propodeum, 

 assign to it the allied one ; and the % will no doubt be found to have the characteristic 

 form of clypeus, when that sex is discovered.

Hab. Honolulu (Blackburn). I have never met with this species. I suspect 

 it of being an introduced species, which apparently has failed to establish itself.

Hab. Abundant all over the islands, especially about houses. No doubt an 

 introduced species. I have received examples from Fiji.
