NOTES ON CULICID/E AND THEIR LARV^ EROM J'ECOS, 



NEW MEXICO, AND DESCRIPTION OF A 



NEW GRABHAMIA. 



BY FRED. V. THEOBALD, M. A., BRITISH MUSEUM, LONDON, ENG. 



A small collection of mosquitoes has been sent me by Dr. Grabham, 

 collected by himself and Mr. T. D. A. Cockerell at Pecos Canon, New 

 Mexico, U. S. A. 



This collection was made in June and contains five species, namely : 



1. Theobaldia incidens, Thomson. 



2. Culex Kelloggii, Theobald. 



3. Culex consobriiius, Desvoidy. 



4. Grabhainia Curriei, Coquillett. 



5. Grabhamia vittata, nov. sp. 



1. The Theobaldia incidens, Thomson (5 $ s), show very evident 

 pale leg banding on the hind legs in one or two specimens, and the 

 position of the posterior cross-vein also varies, for one has it just before 

 the mid cross-vein, another specimen just behind the mid. They were 

 taken on the i8th, 27th and 29th of June. The largest specimen 

 measures 1 1 mm. in wing expanse. 



2. Culex Kelloggii, Theobald. (Canad. Entom., Vol. XXXV., 

 p. 211, 1903. — (Sc^s and i ? ). This species was bred by Dr. Grabham 

 from long-siphoned larvae and only a very few specimens were found. 

 They are quite typical, but the ^ s are much smaller than the type, one 

 only being 4 mm. long. They were bred from the 19th to the 27 th of 

 June. 



The larva of C. Kelloggii. — Head bright testaceous ; eyes black, a 

 black band behind ; antennae black, at the apex acuminate, ending in 

 three long black spines and one very small one ; just above the junction 

 of the dark and pale areas is a fan-shaped set of hairs. Thoracic hairs as 

 follows : The frontal band composed of two large median triple hairs, a 

 couple of small ones next, then two single ones, followed by two triple 

 ones outside ; the next lateral area composed of two outer densely 

 compound groups, then on the inside a double and single hair ; third area 

 composed of two compound bunches. The siphon as long as the three 

 preceding segments, pale testaceous black at the apex and with a black 

 basal ring and black spot, a row of small bristles on its basal half and a 

 line of fine hair tufts on the apical portion, these are four in number
