DYTISCUS HABILIS SAY IN TEXAS 
In the Schaeffer collection of Dytiscus, which was recently 
presented to the Museum of Comparative Zoology through 
the kindness of Mr. Kenneth W. Cooper, were two male 
specimens of Dytiscus habilis Say from Alpine, Texas, dated 
June 2. This Mexican species seems not to have been re- 
corded before north of the border. It is close to C. margini- 
collis Lee. but is smaller (24 to 26 mm. long), more evenly 
oval, with prothorax even more broadly margined with 
yellow in front and behind. These two Texan specimens 
have been compared with four from Mexico in the M.C.Z.

LOXANDRUS 1NFIMUS BATES IN TEXAS 
Of Loxandrus infimus Bates, previously known only from 
Mexico and Central America, I took a series at Brownsville, 
Texas, June 11-16, 1933, at light and in cracks in dried mud 
on the edge of a pond. Dr. Fritz van Emden has kindly 
compared two of my specimens with Bates’ types in the 
British Museum. This species differs from all other Loxan- 
drus found north of Mexico in being dull and not iridescent, 
with distinct alutaceous microsculpture on the elytra.
