heaped about the bases of clumps of sycamores, where they can 

 often be observed in immense numbers. 



Hippodamia parenthesis Say. — Very rare. Occurs on squash 

 vines at Poway. Identical with eastern examples in my collection. 



Coccinella g-notata Hbst. — Plentiful. Confined to the coast 

 region ; not observed in the interior — at least, fourteen years' col- 

 lecting has failed to discover it at Poway (fourteen miles from 

 coast, elevation 700 feet) and higher altitudes. 



Coccinella calif ornica Mann. — Very common. This species, 

 besides being aphidivorous, feeds upon the buds of the wild sun- 

 flower {^Helianthiis californica). Interbreeds with the preceding 

 species. 



Coccijtella sayiguinea Linn. — Plentiful throughout the county. 



Coccinella abdoniinalis Say. — Not common. Frequents citrus 

 groves, loco-weed (^Astragalus leiicopsis), and pig-weeds {Cheno- 

 podiwn). 



Psyllobora tcedata Lee. — Plentiful on plants along water courses 

 and in vineyards. Have observed them feeding upon a small 

 aphis infesting the under surface of the grape leaf, where the 

 beetle was also noticed in all stages of development. 



Chilocorus cacti Linn. — Quite abundant in certain localities 

 upon Agave americana, Astragalus leucopsis, and citrus and olive 

 trees infested with the Black Scale. 



Exochomus pilatei Muls. — Rare. Occasionally taken with the 

 preceding species on Astragalus leucopsis. 



Exochomus marginipennis Lee. — Moderately common on dif- 

 ferent flowering shrubs, especially Przinus demissus. 



Scymnus lophantha^ Blais. — Vortriede's Ladybird is not widely 

 distributed, occurring mostly on the Coronadian peninsula. In 

 color, the elytra are a shining black, with a feeble purpurescent 

 lustre, and not strongly metallic as stated in my descrption in 

 Ent. News, March number p. 51. Post-coxal arcs distinct in 

 outline, semi-circular; outer margin feebly concave, terminating^ 

 at apex of metathoracic episternum. 



Scymnus marginicollis Mann. — Plentiful everywhere. 



Several undetermined species of Brachyacantha, Hyperaspis 

 and Scymnus. 



* We are informed by the Agricultural Department at Washington that this is one of the 

 introduced Australian species, the name of which has not yet been ascertained.— Ed.
