light- yellow, valve long encircling the base of the plates ; plates to- 

 gether wedge-shaped, somewhat longer than their width at base, 

 slightly constricted one third the distance from tip. 



Described from seventeen examples collected in Mexico (Osborn). 

 Readily separable from 4-punctata by the narrower form and from con- 

 stricta by the truncate 9 segment. 



Agallia constricta V. D. 



Can. Ent., XXVI., p. 90, 1894. 



Size oi modesta nearly, but with shorter ehtra, smaller than 4-punc- 

 iaia, el\ tra less convex, light testaceous with four black spots as in the 

 former sjjecies. Length, ? 3.5o-4mm; c? considerably smaller. 



Vertex proportionately wider than 4-punctata, posterior margin 

 slightly elevated, anterior margin rounding to the face. Front broad 

 at the base, snddenl\ narrowing before the middle, from there convexly 

 narrowing to the clypeiis. Pronotum similar to modesta, longer than 

 in 4 punctata, humeral margin more oblique than in viodesta, posterior 

 margin truncate or ver\ slightly excavated. El) tra longer and nar- 

 rower than in 4-piinctata, folded |)erpendicularly together at the tip, 

 obliquely at ba^e, only slightly convex. 



Color: Light tfstaceous yellow, two round spots on vertex, two 

 more on posterior margin of pronotum and the antennal pits black, a 

 narrow median line on pronotum and vertex, the facial sutures, a nar- 

 now line next each eye, an oblique mark on the humeral margin of 

 pronotum and two approximate spots near the anterior margin brown- 

 ish testaceous. 



Genitalia: V, ultimate ventral segment long, nearly parallel-mar- 

 gined, posterior half abruptly constricted, roundingly depressed on 

 either side a carinate median line, posterior margin obtusely rounding. 

 S', valve long, compressed ; plates long and narrow, broadest at the base, 

 constricted in the middle, widening again to the rounding tip ; pygo- 

 fers prominent, laterally compressed, about equaling the plates. 



Specimens are at hand from Long Island, N. Y., D. C, N. J., Ky., 

 Fla., La., Miss., and Texas. Readily se|iarable from the two preced- 

 ing by the constricted? segment. 



Agallia Producta n. sp. 



Form of constricta but longer, as large as 4-punctata, with longer, 

 narrower elytra. Dark smoky-brown, with larger black spots arranged
