Hab. Arroyo, 10 miles west of La Luz, New Mexico, at 
light, Aug. 23 (C. H. 7. Townsend). 
I sent some account of this insect to Mr. H. L. Viereck, 
who was kind enough to look it up in the Cresson collection. 
He reports it very like Portzon hyalinipennis, Cresson, from 
Texas. It will be known from P. hyalinipennis by the paler 
markings, very milky wings, and clypeus largely black. 
These insects differ from typical Portzon by not having the 
femora or tibiz swollen and having the basal joint of hind 
tarsus slightly longer than the two following ones united. 
The hind tibia is very much longer than the basal joint of 
hind tarsi. ‘The eyes are oval, their anterior margins almost 
parallel. 
Ceratinide. 
Ceratina Titus?, sp. n. 
? .—Length about 8} millim. (the type specimen has the 
head thrust forward, and so appears longer). 
Head, thorax, and legs black, the only metallic colour being 
a slight greenish tint on prothorax, hind border of meso- 
thorax, postscutellum, and metathorax ; a longitudinal mark 
on middle of clypeus, narrow and sharply pointed above, a 
narrow stripe on anterior orbits up to level of antenne, its 
inner edge very irregular, and a stripe behind each eye pale 
reddish (possibly yellow altered by cyanide) ; abdomen black, 
with a hardly perceptible greenish tint; antenna black, 
flagellum pruinose. ‘legule shining very dark brown, with 
lighter margins. Wings strongly infuscated, nervures and 
stigma very dark brown; second submarginal cell narrowed 
above, third very broad above. Head and thorax strongly 
punctured ; mesothorax with the usual smooth space and five 
impressed lines; basal margin of metathorax shining, with 
numerous little ridges, but the greater part of the basal area 
dull and microscopically tessellate; abdomen with the first 
segment smooth, the second and third strongly punctured,
