FAM. CULICIDyE 2 3 



20. Genus THEOBALDIA Neveu-Lemaire 



Theobaldia, Xeveu-Lemaire. C. r. Soc. Biol. Paris (29 Nov. 1902). 



Characters. — Head and scutellar scales narrow-curved, except at the sides of the head where 

 they are flat, there are also upright forked scales on the head. Palpi long in the cf, the two apical joints 

 swollen, composed of thiee segments, and three incomplete pseudo-joints, the two apical segments and 

 apex of the antepenultimate with hair-tufts. Wings with man}- large lanceolate scales, which become 

 collected into patches forming more or less distinct spots. 



The members of this genus form a very natural group, easily told by the q* clavate palpi and the 

 lanceolate wings scales often collected into definite spots. They were all previously placed in Culex. 



Geographical distribution of species. — All the species belong to temperate climates, when 

 thej" occur elsewhere it is usually in the hills. They are domestic forms and thus are easily distributed 

 by artificial agencies.

Grabhamia. Theobald, Mon. Culic. Vol. 3. p. 243 (1903). 



Characters. — Allied to both Culcx and Taenioi'hynchus. Head clothed with rather broad curved 

 scales, upright forked scales and flat lateral ones. All the thorax with narrow-curved scales. Palpi of 9 

 composed of 4 segments, the apical one minute; rj 1 palpi long, the two last segments swollen and with 

 distinct hair tufts. Wings rather short; fork-cells short ; median vein scales rather thick, lateral ones 

 rather short and broadish. neither so long nor as dense as in Taenioi'hynchus ; scales of wings mottled and 

 also the le^s mottled and spotted. 



.- laid singly idorsalis, jamaicensis, etc.), larvae with short siphon when adult. 



Geographical distribution of species. — Twelve species occur in this genus, the majority 

 e from Europe and North America. Previously placed in the genus Culex.
