ground pea Lathyrus venosus 30 May, 1907; they spun reticulate 

 white cocoons, one of which I have seen, and transformed to 

 adults June 28, 1907. Mr. A. B. Wolcott tells me that he also 

 has bred it from the same locality and that the larva is deep 

 green in color. The cocoon is pure white and rather loosely 

 woven. 



Phytonomus maritimus new species. 

 Phylonomus rumicis: 



1909: Webster, R. L.: Entom News, 20: 81. 



Adult: (Plate XXIX, figs. 8-9). Length, 5 to 6.5 mm. Width 2 

 to 2.5 mm. Stouter and thicker than trivittatus, elytra much more 

 declivous; reddish black, clothed with pale yellow scales and white and 

 black hairs. 



Head densely pubescent with rather stout hairs, a few notched at tip; 

 beak with a smooth median carina, front between eyes narrow, an elongate, 

 narrow, polished groove above the antennal groove; eyes elongate oval 

 rather large; antennal groove deep, black, smooth; antenna reddish, 

 scope reaching margin of eyes, longer than first six funicle joints, club 

 elongate oval, second and third joints shortest, fourth rather long 

 pointed at tip, entire club finely pubescent with gray hairs. 



Prothorax not polished, narrower in front than behind, widest in 

 middle, shaped much as in trivittatus but sides are fuller and more 

 rounded; punctures large, often confluent; dorsum of prothorax with 

 two wide dark bands separated by a very narrow, light line, sides 

 darker than center line; in some specimens the dorsum is entirely light. 

 Scales broad, deeply emarginate, striate; hairs stout, white and usually 

 notched at tip, sides parallel; seutellum very minute, covered with fine 

 gray or white pubescence. 



Elytra at base but slightly wider than prothorax, one of the Nan- 

 tucket Id., specimens tessellated almost all over, the darker spots 

 alternating along the central line; elevations between stria-, each with 

 a single row of white hairs, each hair stout, parallel-sided and notched 

 at tip; stria? with a fine short pointed white hair in each puncture. All 

 the hairs semi-decumbent; scales on the elytra more elongate than on 

 thorax, processes more slender and pointed; the dark spots are velvety 

 black scales, rarely with a black hair on the part of the interspaces where 

 they occur; there is a tendency on all the specimens for a black band to 

 occur on the third interspace beginning at the base of each elytron and 

 gradually fading out. 



Venter; scales more of the shape of those on the elytra than of the 

 thoracic scales, prosternal process short, triangularly pointed; meso- 

 sternal process between middle coxae long, curved, pointed; intercoxal 

 process of third abdominal (first visible) segment broad, rounded almost 

 to the center and terminating in a short, sharp point. In the male this 

 segment is emarginate posteriorly. 



Legs; dark red, clothed in front with elongate emarginate scales, 

 tibial crown of spines pale red or yellowish red, a distinct emarginate 

 process on each tibia at the tip, not as prominent as in serialtis.
