HACKBERRY BEETLES. 611 
one-half longer than wide, apical joint minute; labial palpi apparently two-jointed, 
basal twice as long as wide, apical minute. The body tapers from the large pro- 
thoracic joint to the ninth, the last three joints slightly enlarged ; tip of abdomen 
rounded and subtruucate ; horny areas on dorsum, and venter of each joint as in 
other allied larvae ; prothoracic joint thickly armed with yellowish hairs, especially 
about the anterior and lateral portions ; following joints sparsely armed with hairs 
on the lateral portions; thoracic legs wanting. 
Pupa. — Female. Length, 15 mm ; diameter, 8 mm . Color, yellowish-white. Viewed 
from above, the first thoracic joint is widest and the second narrowest. The abdo- 
men tapers regularly to the truncate tip ; abdominal joints 1 to 6 narrow, subequal; 
seventh as long as wide and nearly as long as the three preceding^ together. Dor- 
sum of joints armed with minute brownish points ; femora at tips armed with five 
or six minute spines tipped with yellowish hairs. The wing-cases extend to the tip 
of the fourth abdominal joint, posterior feet to tip of the seventh joint. The antenna? 
pass back of the femora of the two anterior pair of legs, turn at the tip of the wing- 
cases, and reach in front to the base of the middle pair of legs. 
15. The Eyed Elater of the Hackberry. 
Alaus lusciosus Hope. 
This insect is hardly distinct from the common Eyed Elater (Alans 
oculatus Linn.), and the larvre and pupre of the two species are practi- 
cally identical. Some very slight differences occur in the armature of 
the last segment of the larvse, but these may be variable, and at any 
rate are so slight as to be of no value in separating the two species. 
The common species is known to pass its growing stages in the 
decaying wood of various trees and is mentioned by Dr. Packard on 
page 424. 
On May 26, 1879, Mr. Schwarz found a larva of an Alaus under the 
bark of Geltis texana at Columbus, Tex., which may be referred with 
little doubt to A. lusciosus, as a perfect insect of this species was found 
at the same place in July and August. 
16. The Celtis Bark-borer. 
Scolytusfagi Walsh. 
Order Coleoptera; family Scolytid.e. 
A whitish, thickened grub one-fourth inch long, occurring under the bark of 
Celtis texana, boring partly in the wood and changing in July into a shining black 
beetle about three-sixteenths of an inch long. 
This beetle was described by B. D. Walsh in the Practical Entomol- 
ogist, vol. 2, p. 58, February, 1867, and the following statement was 
made concerning its habits : " I obtained many specimens from south 
Illinois from what I believe was a beech." 
Dr. Le Oonte, in Rhynchophora of America, north of Mexico, gives 
it, on the authority of Walsh, as depredating on the Beech, but -the 
above reference shows that this food habit can not be positively 
asserted of it. 
I have examined the work of this insect under the bark of Celtis texana 
in Texas, and Mr. Schwarz has collected it in large numbers at Golum-
