Sept. I900.] KuNZE : OvA AND Larva OF Hyperchiria Pamina. 201 



small granules close to the anterior margin, no eyes. Venter and coxk with similar 

 granules, often giving rise to a fine hair. Palpus large, stout ; femur more than twice 

 as long as broad, with about four pointed tubercles above and below on outer side 3 

 long spines toward base, one on inner side toward tip ; patella nearly as long as the 

 tibia, four tubercles above, and below on each side one long spine ; tibia about two and 

 one-fourth times as long as broad, with three spines below on each side, the middle 

 one much the largest, the apical one next in size ; tarsus about three-fourths the length 

 of the tibia, with two spines below on each side, the basal one the larger ; claw slen- 

 der, nearly one-half as long as the tarsus. Mandibles with some tubercles in front and 

 above. Legs slender, finely granulate ; femur I reaches to tip of femur of palpus ; 

 the patellae are larger than the other joints and quite long, the tarsus is divided into 

 long slender joints, all clothed with fine short hairs. The posterior margin of each 

 abdominal segment above and below is elevated. Length, 1.8 mm.

NOTES ON OVA AND LARVA OF 

 HYPERCHIRIA PAMINA. 



By Dr. R. E. Kunze. 



While collecting in Prescott, Ariz., found a 9 Pamina, June 23, 

 189S, which oviposited, June 24th, one hundred eggs. I retained 

 thirty, which hatched twenty days later, July 13th, 8 A.M., exact 

 time for first larvae to appear, I sent sixteen ova to Professor Packard, 

 and gave the others to a friend on the Summit Mountains to raise 

 if possible. Nights were very cool, and thought that no ova would 

 hatch, so long in coming out. 



6>zw/« white, a black spot on top. Length, 2 mm. Width, i^ 

 mm. Shape subconical, depressed on sides. Ova laid in piles com- 

 posed of parallel rows. 



Young /a rvce after hatching: length 5j-6 mm. when in motion, 

 and 4 mm. at rest. Width of body 4 mm. Color dull orange or 

 buff, head black. Dorsum with double row of gray tubercles, sur- 

 mounted by black bifurcated spine. A subdorsal row of tubercles 

 of a greenish-gray. Lateral parts below covered with whitish hair. 

 Head shining black, covered sparsely by whitish hair. Thoracic and 

 prolegs concolorous with body. A few hours after hatching larva 

 changed to a brownish color, spines black. Larvce were fed on Quer- 

 cus undulata.
