slightly expanded over the antennal pits. Pronotum broad and short, 

 wing pads long, oblique, abdomen compressed and carinate dorsally 

 as in 4-putictata, in color reddish-brown, margins of segments and of 

 facial pieces slightly lighter, an oblique fuscous band from base of 

 crest to the venter on third segment and another from the crest of the 

 fourth segment to the venter on sixth. 



Life History: Larvae were found with those oi 4-punctata in Janu- 

 ary and again in May. They continued to be found for some time 

 after the latter had all issued. The adults were common, both males 

 and females, nearly through July. The larvae appeared in August, a 

 few weeks later than those of 4-punctata, with which they were found 

 constantly associated. They become nearly full grown by fall and 

 pass the winter under the leaves and rubbish to pupate in early spring 

 and later appear as adults. 



Agallia tenella n. sp. 



Similar to novella in appearance, elytra longer and more pointed 

 behind, spots on pronotum obscure brownish. Length, 4.25 mm.; 

 width, 1.25 mm. 



Vertex similar to novella in shape, margin behind eyes nar- 

 rower, less constricted outwardly, face broad, short, genae paral- 

 parallel-margined below the eye, then slightly inflated before rounding 

 to the lorae. Front broad and short, width at base nearly equal to 

 length, narrowing nearly uniformly throughout to the clypeus, lorae 

 twice longer than wide, frontal suture obtusely angulate, the apex 

 reaching nearly the level of the ocelli. Pronotum finely granulated 

 much as in novella, humeral margins longer, less rounding, elytra long 

 and very narrow, two transverse nerves between the first and second 

 sector, veins on clavus approaching very closely on the middle half. 



Color: Light-gray with vertex and scutellum yellow, spots on ver- 

 tex and pronotum dark. Face light-yellow, sutures dark-brown, inner 

 pair of spots on vertex small, outer pair larger than in novella, not as 

 far behind eye, as large as the inner pair. Pronotum light-gray with a 

 median line and two obscure spots near the middle on either side red- 

 dish-brown, scutellum yellow with a triangular spot near the basal 

 angle on either side, two spots and a transverse line on the disc black. 

 Elytra smoky sub-hyaline with light nervures and light sutural margins 

 interrupted by a dark saddle between the claval nervures and another 

 at the base of the inner apical cells.
