THE FAMILY EUCHARmAE — GAHAN 429 



Holotype female, allotype male, and 23 paratypes collected by C. P. 

 Clausen, at the type locality in February 1930 under Clausen No. 

 2432. Also 1 paratype taken at quarantine in Honolulu, Hawaiian 

 Islands, May 8, 1931, on Ooelogyne sp. from Straits Settlements. 



Genus PARAPSILOGASTER Girault 



PARAPSILOGASTER LAEVICEPS, new species 



I am in some doubt as to the true generic position of this insect. 

 The antennae are 12- jointed. The ring joint is entirely absent, and the 

 club has three rather distinct although imperfectly separated joints. 

 The head is perfectly smooth, the occiput rather deeply concave and 

 the angle formed by it with the vertex sharp and margined by a weak 

 carina behind and very close to the ocelli. The mandibles are as in 

 Orasema. The labial palpi are 3-jointed, as are also the m.axillary 

 palpi. The pronotum is mostly concealed from above, the mesoscutum 

 short, strongly declivous anteriorly and weakly rugulose, with the 

 parapsidal grooves deep and complete. The axillae are broadly united 

 medially and weakly longitudinally wrinkled. The scutellum has a 

 transverse fold at its apical one-third, is perfectly smooth behind the 

 fold but irregularly rugulose in front of it, and is entirely without 

 processes. The propodeum is about as long as the dorsal aspect of 

 scutellum before the fold, mostly smooth, without lateral folds and 

 usually without a median carina, the spiracular grooves well defined. 

 The legs are slender, their tarsi normal. The abdominal petiole is 

 irregularly longitudinally rugulose, about twice as long as the pos- 

 terior coxae and not especially slender. The gaster is smooth, strongly 

 elevated, its ventral length subequal to the length of petiole, its height 

 nearly twice its ventral length. The ovipositor is thick and armed 

 with very distinct saws. The wings are normal, the costal cell moder- 

 ately broad, the stigmal vein short and sessile, and the postmarginal 

 vein weak but longer than stigmal. 



The above characters, except for the smooth head, long abdominal 

 petiole, and possibly the number of joints in the palpi, seem to agree 

 fairly well with the characters for Parapsilog aster Girault as given 

 by Girault ^ and amplified by Ishii.^ No authentic representatives of 

 Parapsilog aster are available for comparison, and it is quite possible 

 that this new species may eventually be found to represent a new 

 genus. 



Female. — Length 2 mm. Head polished, thin anteroposteriorly ; 

 ocelli in a very low triangle, almost in a straight line; postocellar 

 and ocellocular lines subequal; scrobes distinctly impressed, moder- 

 ately deep; clypeus a little broader than long, polished, its anterior
