orange hair on inner side; spurs red; middle of abdomen with the 
punctures sparse and small, on the fifth segment minute but close, in 
abrupt contrast; hind margins of segments, and edge of basin of 
first, with conspicuous but very narrow white hair-bands, but no 
other hair-bands or markings; sixth dorsal segment delicately keeled, 
gradually narrowed apically, and turned up at extreme tip; last 
ventral rather narrow, with a very apical part, not extending far 
beyond dorsal; sides of last ventral with long but not dense hairs ; 
ventral segments with strong white marginal hair-bands ; last ventral 
black or nearly, contrasting with the bright red segment before it.

U.S. National Museum. This species may be compared with 
some of those described by Cresson from Mexico, from which it 
is readily separable as follows :— 
Last dorsal segment abruptly contracted on each side, the 
apical part much narrower than the basal... chichimeca, Cress. 
Last dorsal gradually tapering to apex............... i P 
1. Last dorsal turned upward at tip; last ventral straight 
costaricensis, Ckll. 
Last dorsal not turned upward at tip; last ventral strongly 
Curved: downward wasiicde asco se useeeoecmscesseres totonaca, Cress. 
C. costaricensis is in many ways similar to the South 
American C. querens, Holmbg., to which it runs in Holmberg’s 
table. 
Celioxys luzonicus, sp. nov. 
3. Length about 7 mm.; black, head and thorax above very 
densely punctured; head broader than thorax; mandibles entirely 
black; hair on eyes short; face and front with pale golden hair, and 
scape beneath with long hair of the same colour; antenne entirely 
black ; mesothorax with even posterior middle excessively densely 
punctured ; cheeks covered with white hair, no hairless area below ; 
occiput with white hair; mesothorax with very thin golden-brown 
hair, only distinct anteriorly; pleura, tubercles and sides of meta- 
thorax densely covered with pure white hair; scutellum dull, very 
densely rugosopunctate, short, the margin simple, except when looked 
at from in front, when two very small obscure nodules appear ; 
axillar teeth short; tegule black ; wings dilute fuscous throughout ; 
b. n. meeting t. m., first r. n. joining second s. m. very near base ; 
legs entirely black, with white hair; hair on inner side of hind tarsi 
orange-fulvous ; spurs fuscous; abdomen shining, strongly but not 
densely punctured, the hair-bands pure white; marginal hair-bands 
confined to sides, where they form broad patches, on first segment 
sending a very large lobe basad, and a thin line mesad to near the 
middle; subbasal bands developed as small stripes on sides of third 
segment, but nearly meeting in middle on fourth and fifth; sixth 
segment very short and broad, with very small lateral basal teeth 
(minute ones also on fifth), and six (three pairs) at apex, four above, 
and two (longer) below; ventral segments with broad white hair- 
bands, the first with a median patch of hair extending from base to 
hind margin, but the margin otherwise bare.
