8. Another Philippine Chloeepyius. 



Chlorepyris similis n. sp. 



9 Resembling closely and closely allied to C. flavipcnnis Kieffer but 

 differing in the more shining integument of the head and thorax and 

 the finer and sparser puncturation of the head, largely impunctate 

 behind the ocelli, the finer and sparser puncturation of the pronotum, the 

 shorter pronotum and propodeum, and paler, more elongate stigma of 

 the wings, and the paler flavo-piceous tibiae and tarsi. Length 7 mm. ; 

 wing 5.5 mm. 



$ The male closely resembles the female. The antennae and legs 

 are more slender and the abdomen smaller, as is characteristic for males. 



Length 7 mm. ; wing 5 mm. 



Described from one 5 and one $ collected at Los Banos, 

 Lnzon Philippine Islands (F. X. Williams). Type and allo- 

 type in the author's collection. 



9. A Xevv Peregrine ScleroCxIbbine Betiiylid Genus from 

 THE Hawaiian Islands. 



Lithobiocerus n. gen. 



Apparently related to Mystroconcmis Kieffer but with the mesothorax 

 strongly contracted into two unequal lobes and with the legs differently 

 developed. 



Head flattened above, suboval in the dorsal aspect, truncate behind. 

 The eyes coarsely facetted, rounded, hairy, reaching to the occiput and 

 diverging anteriorly ; ocelli none ; front produced over base of antennae 

 concealing the antennal sockets and clypeus, its anterior margin revealed 

 snoutlike between the bases of the antennae ; antennae inserted between 

 the frontal process (anteriorly) and the clypeus (posteriorly) ; clypeus 

 declivous, tectiform, carinate at its extreme base, swollen in the middle, 

 its base anterior to its apex. Antennae stout, tapering, 25-jointed, the 

 joints broader than long; labial palpi elongate 6-jointed. 



Prosternum massive plane, declivous in front ; pronotum arcuately 

 emarginate behind, narrowed behind, about twice as long as broad at 

 base, a little longer than the propodeum, twice as long as the mesono- 

 tum; mesonotum contracted before the middle. Propodeum broader 

 posteriorly, obliquely truncate without ridges or carinae. Front tibiae 

 and femora strongly incrassate ; hind and middle tibiae about the length 

 of their femora, the front tibiae about one-third as long as its femur and 

 somewhat spoon-shaped. Anterior tarsus with large conspicuous pulvil- 

 lus between the ungues, inconspicuous on the hind and middle legs ; 

 ungues with a subapical tooth; calcaria feeble 1-1-2, those of hind legs 

 unequal. Type Lithohioccnis vagabuudus Bridwell.
