BULLETIN OF THE BROOKLYN E OT. SOC. 19 



Of the nine pairs of stigmata the first is situated near the an- 

 terior margin of the mesothoracic fold, the other eight pairs are 

 on the pleurites [see Bulletin No. 2 page 11] of the first eight ab- 

 dominal segments. Ventral part of ninth segment consists of 

 two slightly protruding fleshy propellers. 



Larval State of Eleodes Gigantea. 

 Head convex ab ove, gular region concave ; all the mouth-parts 

 like Tenebrio ; antennae differing by the stouter 

 2d and 3d joint. Legs, thoracal and abdominal 

 segments with no perceptible difference. Pygi- 

 dium with 18 lateral penicilli and terminal ob- 

 tuse tip, sparsely fimbriate. Color of small in- 

 dividuals (6 mm.) entirely white. No trace of 

 ocelli or even dark pigment spots on the oph- 

 thalmic region. The small larvae from which 

 the drawing is made have the abdominal seg- 

 ment nearly all flat, gradually after several ex- 

 uviations acquiring the typical string or wire- 

 shape and also darker color. The penicilli are 

 a direct prolongation from the hypoderm,pierc-

Fig. 5. A. pygidium of Eleodes dentipes [7 mm. long larva], magnified; 

 j about 4 weeks old. b, anterior leg, magnified. Coxa 

 and trochanter each with two blunt teeth, trochan- 

 ter with two penicilli near tip, and femur with four 

 Ipenicillia at middle. Simple claw with rudimentary 

 F 'g- 5 median fissure at tip and one penicillus at middle. 



Larval State of Eleod. Dentipes. 



Head and mouth-parts, antennae, middle and posterior legs 

 alike as in EL gigantea. It differs by the pygidium having but 

 ten penicilli, the two terminal are slightly longer and run parallel 

 over terminal tip; and also by the form of the anterior leg. 



It is remarkable to state that larvae of but a few hours age have 

 two small blunt terminal penicilli. at the side of w r hich are two 

 stout long bristles, but without lateral penicilli. The latter will 

 appear after the first moult. Length 2-5 mm. 



A number of Eleodes dentipes began to deposit their eggs in 

 April, 78 and the larvae have now the length of 30 to 85 mm. I keep 

 them in a breeding jar with earth and decayed wood.
