dashes on posterior half sometimes united into a single large lunule; 
legs blackish to black, tarsi brownish; general shape, somewhat pointed 
posteriorly; length 4-5 mm., width 2-3 mm. 
Egg: Fig. 10, Plate XXXII. 
Amber yellow; length 1 mm., width .4 mm. 
Larva: Fig. 11, Plate XXXII. 
First instar; general color grayish or blackish; head shining black 
except medio-anterior portion, setaceous spots black, as in all the other 
species reared, dorso-lateral and lateral portions of first and dorso- 
lateral portions of fourth abdominal segment pale, nonsetaceous portions 
of thoracic segments rather pale. Final instar; head black except 
medio-anterior portion, which is brown; pronotum bordered with pale, 
meso- and metathorax with whitish median portion; yellow markings 
as follows, lateral and dorso-lateral spots on first and dorso-lateral 
spots on fourth abdominal segments orange yellow, and faint indica- 
tions of dorso-lateral spots on fifth, sixth, and seventh segments pale 
yellow; length 8 mm. 
Life cycle records were made as follows: 
Egg stage (1 record) 3 days. 
Larva stage (1 record) 11 days. 
Pupa stage (1 record) 6 days. 
Egg to adult, 20 days. 
This life cycle appears relatively short, but this is probably 
due to the fact that this batch was reared in July when the 
weather was specially favorable. 
This species, like H. stnuata, has been found chiefly in the 
grass and Carex feeding on Rhop. braggiu and Chait. fabellus, 
tho in the breeding cage it seemed to thrive on Rhop. pastinceae. 
Coccinella 5-notata: Kirby. 
Ranking next in order, or perhaps equal with H. convergens 
in economic value, is Coccinella 5-notata. This is somewhat 
larger and more robust species and may be described as follows: 
Adult: Fig. 12, Plate XXXII. 
Head black with triangular pale spot next each eye; pronotum black 
with subquadrate pale spot at the anterior angles; elytra brownish red, 
marked with common subbasal fascia and a transverse spot on each 
elytron before the middle, near the suture, and another at apical fourth. 
Sometimes the subbasal fascia is broken into three spots, sometimes 
there is also a dot on the anterior lateral portion of the elytra. Length 
5.5 to 7.5 mm.; width 4.5 to 5.5 mm. 
Eggs: Fig. 13, Plate XXXII. 
Light to deep amber yellow in color; length 1.31 to 1.37 mm.; 
width .53 to .60 mm.
