hair is deeply serrate, but not at all feathery, short and without very long 

 hairs except at the posterior end where there is quite a mass of long hair 

 extending backward. The lateral hairy ridge notched by Dyar in opella is 

 not conspicuous. 



Structurally the head agrees with the other Arctiin^, but is decidedly 

 more hairy than most. Epicrania quite hairy over the entire face, though less 

 so, perhaps, than in Ctenucha. Front with punctures very far apart, with 

 two or three secondaries, among which the primary is not recognizable. Ad- 

 frontals narrow and irregular, without secondaries, the puncture not very 

 high. Clypeus normal, without secondaries. Labrum with ii somewhat higher 

 than i, ia directly over ii but not very far from it. Lower lip normally pro- 

 portioned for the Arctiidje, with very slender labial palpi ; mentum and stipes 

 with dense patches of secondary hair (7 to 10 hairs). The longer hair is 

 serrate, most of the shorter hair smooth. The densely hairy labium separates 

 it from the other arctiid caterpillars known to me. 



Compared with specimens of Lithosia, Hyphantria, Diacrisia, 

 Estigmene, Isia, Apantcsis, Euchcctias, Halcsidota and Ctenucha. 



The figure shows the front {Fr). adfrontals (adf), clypeus 

 (clyp), and labrum seen from the front. The setae of the labrum 

 are numbered. 



OBSERVATIONS ON MEMBRACID^ IN THE VICIN- 

 ITY OF ELIZABETH AND NEWARK, N. J.

The first specimen, a female, was found by me on July 9, and 

 till August 13 I found both sexes constantly increasing in abundance 

 but from that time on, singly, and mostly females. The last was 

 collected September 12, south of Newark, N. J. 



I found 32 eggs in one female collected August 4; 18 eggs in 

 another collected August 6; and 15 in one collected August 13. On 

 this account I venture to believe that the eggs are not deposited all 

 at once but at intervals.
