The three basal areolae of metanotura are less strongly punctured than 

 the rest ; the superior median areola small, distinct, semicircular, broader 

 than long ; posterior median triangular at base ; from that it contracts 

 slightly and ends above the middle of the metanotum, where there is 

 another field longer and somewhat oval in form, which occupies the rest 

 of the middle space; the posterior intermedian area is semiobsolete, 

 small ; spiracular, large, wider at base than at apex; at the base it be- 

 comes rounded and enlarged. Wings hyaline ; areolet shortly stalked ; 

 stigma fuscous." [Ashmead, Fauna Hawaiiensis, I, Pt. Ill, p. 357, 

 1901.] 



In a series of 2n females and 4o males whicli I have examined, 

 I am una])le to distinguish, by Cameron's descriptions and tahlcs, 

 which are hazvaiiense, and whi<-h are blackbiirni^ or wliethcr th(\v 

 are all the same species. None of them agree completely with 

 either description; tho I can separate some of them l)y the dis- 

 tinctions he gives in the markings of the legs, 3'et I have variations 

 hetween, and mj' specimens do not have corresponding differences 

 in pubescence; whereas Cameron makes a difference in pubescence 

 a strong point of distinction l>et\veen the two species. His des- 

 criptions are from a single female in each case, which, from the 

 variations in my series of specimens, I think very inadequate for 

 definite descriptions of species; in fact, he himself says, " I am 

 not sure that if we liad a long series of eacli, it Avould be found 

 that the}' were varieties of one species." If they are to l)e con- 

 sidered as one species, the name L. blackbiirni Cameron, In-ing 

 the earlier described, should have preference. 



I have 1)red tliis native Ophionid parasite from several species 

 of leaf-rollers: eaiie \v\\i-\i.)\\QX [Omiodes accepia)^ palm leaf-roller 

 {O. blackbiirni) , " Wiliwili " leaf-roller(C). ynonogona) , O. localis, 

 Pyi'ajista co7istricta, Homoeosoma hunieralis and from two un- 

 determined species of Phlyctaeyiia. I also l)red quite a large 

 series from the tobacco splitworm {Phthorimaea opoxidella) which 

 Avas badly infesting tomato vines and fruit. Dr. Perkins has 

 l)red them also from Cacoecia, Phlyctaenia despecta -Awd P. i,tellata. 

 Prol)al)ly manj- other species of the smaller Pyralids are parasitized 

 ])y them. I have collected specimens in several districts of Hawaii, 

 in lao Valley, in Honolulu, aud in the mountains near Honolulu. 

 The larva of this parasite eventually kills the host caterpillar, 

 when the latter has become about full-grown. It emerges and 

 spins a compact, light l>r()wn, oblong cocoon on the leaf beside 

 the remains of its host, within the rolled together leaf which the
