Fam. TRICHOGRAMMIDAE. 

 There are several species of this family known in the islands, but it is doubtful 

 whether there are any endemic forms. Those here described are almost certainly all 

 foreign. Several other species are known to me, e.g. a species commonly parasitic in 

 the eggs of the introduced Locustid Eliniaea appcndiculata, and one parasitic in the 

 eggs of the Chrysopine genus Anomalochrysa. All the species invariably shrivel up 

 and collapse within a few hours after death, if not placed in fluid, and are best described, 

 when freshly killed. The genus Westwoodella belongs to the subfamily Oligositinae, all 

 the other known Hawaiian Trichogrammids (including those undescribed) belong to the 

 Trichogramminae. I have described two species under the genus Pentarthron, but this 

 appears to me to be synonymous with West wood's genus Trichogramma. P.flavJtm is 

 perhaps identical with Trichogramma pretiosa. 



Westwoodella Ashm. 



(i) Westwoodella hilaris, sp. nov. 



Head and thorax orange-red or brownish red, varying in tint in dried specimens, 

 abdomen black, with a basal yellowish or reddish, wide ring, sides of thorax posteriorly 

 dark, antennae sordid, darker in parts ; front legs sordid, hind legs with the femora 

 dark, the tibiae and tarsi pale, tips of all the tarsi black or dark fuscous. 



Pedicel, funicle and club of antenna 

 of Westwoodella hilaris 9 . 



Head transverse, collapsed in dry specimens, eyes pilose ; scape of antennae 

 stoutish, narrowed apically, pedicel obconical, longer than thick, funicle joint rather like 

 the pedicel, but considerably less thick and a little shorter, club long pointed, of three 

 subequal elongate joints ; with the ring joint the antennae are seven-jointed.
