Chlorion (Ammobia) sulciscuta (Gribodo). 
Sphex sulciscuta Gribodo, Miscel. Ent. 2 (1894) 2. 
A single male collected at Los Banos, Laguna, Luzon ( E . M. 
Ledyard 102J+) agrees with Gribodo’s description, which is based 
on the female, except in regard to the clypeus, and it seems 
likely that this difference is sexual. The species very closely 
resembles mutica (Kohl) but is readily separated by the bilobed 
metanotum. 
Uniformly black, with black pubescence; wings violaceous; 
face with silvery pile beneath the black hair; clypeus flat, the 
anterior margin broadly and shallowly emarginate. 
Length, 26 millimeters. 
Chlorion (Ammobia) aurulenta (Fabricius). 
Sphex aurulenta Fabricius, Kohl, Ann. Naturh. Hofmus. Wien 5 
(1890) 382; Bingham, Fauna Brit. India, Hym. 1 (1897) 250. 
Sphex ferruginea Lepeletier, Hist. Nat. Ins. Hym. 3 (1845) 345. 
Sphex lineola Lepeletier, Hist. Nat. Ins. Hym. 3 (1845) 353. 
I have followed the synonymy as published by Kohl in 1890 
for this species. Certain of the lists of Philippine Chlorionini 
have treated ferruginea and lineola as distinct varieties. Bing- 
ham, 1897, uses the name lineola for a variety which has the 
pubescence of the head and thorax silvery white; but he is 
evidently wrong, as the original description of lineola gives the 
color of the pubescence as golden. It is possible that what 
Bingham had as lineola is the variety pallidahirta Kohl and that 
Kohl’s variety should be added to the Philippine list. Only 
two varieties are represented in the collections before me. 
Chlorion (Ammobia) aurulenta var. lepeletierii (Saussure). 
Chlorion aurulentus var. ferrugineus Lepeletier, Williams, Bull. 
Hawaiian Sugar Planters’ Assoc. 14 (1919) 124. 
Luzon, Laguna Province, Los Banos ( Baker 368), female. 
Chlorion (Ammobia) aurulenta var. sericea (Fabricius). 
This variety has been recorded from Manila by Kohl (1890) 
and is represented in the collection before me by two males re- 
ceived from C. F. Baker. 
Luzon, Laguna Province, Los Banos, Mount Maquiling 
(Baker 2729 ) . 
Chlorion (Ammobia?) morosa (Smith). 
Sphex morosus Smith, Bingham, Ann. & Mag. Nat. Hist. VI 16 (1895) 
443; Bingham, Fauna Brit. India, Hym. 1 (1897) 246. 
In 1895 Bingham recorded as doubtfully belonging to this 
species a female collected at Cape Engano, Luzon, by Whitehead,
