Coleopterous Fauna of Lower Rio Grande Valley. 99 
or two larvae were found, and a few pupae, but there were hundreds of 
adults, all inside the trunks and not yet emerged. This therefore is the 
season of their appearance, as shown by the fact that a few adults were 
beaten from the lower dead leaves of the yuccas and some found under 
yucca logs. Length of the largest specimens, fifteen mUt. or more, not 
including snout. The small ones are half that size. Color, brownish- 
black; elytra thickly sprinkled with pale, dirty cream color; thorax on 
sides with same color, more or less nearly meeting on margin behind, but 
not reaching front margin. In the smaller specimens the creamy sprink- 
ling is less apparent or obsolete. Distr. New to the United States fauna, 
and probably occurring in Mexico. 
507. Macrancylus linearis , Lee. — A colony of thirty or forty found by 
Schwarz under a log on the south end of Padre Island, June 8th. Eleven 
taken under drift on Padre Island, June 29th, Wickham on same date 
finding a colony of fifty on underside of wide flat plank, being a piece of 
wreck of oak wood. The latter is a larger colony than Wickham ever 
found on the Florida Keys. This genus lives only on the open coast line, 
not on lagoon coasts. It lives in colonies under drift wood, which must 
be pine (not oak) in Florida, or wood without bark and partly soft so 
that the larvae can breed in it. The weevils are found motionless and 
clinging to the wood when turned over, and occur in not too wet or too 
dry places. Distr. The genus is Antillean. The species is strictly mari- 
time and semi-tropical. Southern Florida coast and keys and Southern 
Texas and Mexican coast and keys. The species was originally found on 
the seashore at Haulover, Florida, by Hubbard and Schwarz. 
508. Amaurorhinus nitens , Horn. — One specimen beaten from Cle- 
matis drummondii tangles near Rock’s Resaca, June 25th. Distr. South- 
ern States to Southern Texas. 
509. Amaurorhinus , sp. — Taken by Schwarz in June. Distr. Hew to 
United States fauna. 
SCOLYTIDAE. 
510. Hypothenemus erectus , Lee. — Many specimens of this very small 
scolytid were bred from dead fig twigs, issuing all the time from March 
12th to June 14th. In all more than forty were bred. Distr. Hew Jer- 
sey to Texas. Breeds in hickory and oak in Hew Jersey. 
511. Hypothenemus dissimilis, Zimm. — Bred with H. erectus from 
dead fig twigs, but in less numbers. Distr. Hew Jersey and Georgia to 
Lake Superior and Texas. Breeds in grape and oak in Hew Jersey. 
512. Hypothenemus , sp. — This probably new species was also bred 
with H. erectus from dead fig twigs. Distr. Hew to the United States 
fauna and probably occurs in Mexico. 
513. Phloetribus, sp. — Beaten from foliage in palmetto thicket at
