88 C M. Osten Sacken: Diptera 



The Diptera of the Philippine Islands. 



Tipnlidae. 



Dicranomyia saltans Dolesch. 2 Bijdr. 14, Tab. II, f. 3 

 {Limnobia saltans; Java). — 



Remarkable for the unusual shortness of the cells in the apical 

 portion of the wing and the slenderness of the legs. The venation 

 and the absence of spurs and empodia prove it to be a Dicranomyia. 

 Doleschall calls the antennae 16 -jointed; as far as I can discern, the 

 only antenna of my only specimen has the normal number of 14 joints. 

 According to the same author, this species is very numerous during 

 the season of the dry monsoon ; it is often found in dwellings, principally 

 in the corners, in large numbers, dancing up and down in the air; 

 they keep so close together that they seem to hold each other in 

 dancing, and to form a regular chain. 



Liihnotes Semperi n. sp. $. Thorax bright orange; 

 abdomen deep black; wings uniformly brown. — Length: 11 — 12 mm. 



Head reddish-brown; rostrum, palpi and antennae black. The whole 

 thorax, including coxae, bright orange. Halteres brown, extreme base 

 orange. Abdomen deep velvet black, except the extreme base, which 

 is orange. Legs brown. Wings uniformly brown; bases of the 2°"* 

 and 3'''* post. c. on the same line; first vein incurved towards the second. 

 — A single female. 



Libnotes termitina n. sp. ^ Q. Uniformly yellowish- 

 orange; extreme tip of the abdomen black; wings brown. Length; 

 11—12 mm. 



Antennae black (reddish at the base in one of the specimens); 

 rostrum brownish; palpi brown; halteres with a brown knob; stem paler; 

 legs brown; femora more or less yellow, but brown towards the tip. 

 In the male, the genitals are deep-black, in the female, the last abdominal 

 segment, although the valves of the ovipositor have the usual, brownish- 

 ferruginous color; they are very short. Wings tinged with brown (less 

 dark than L. Semperi); this color is rather uniformly spread over the 

 whole surface; the apex is slightly darker. First vein incurved towards the 

 second ; bases of second and third post. c. on the same line. — A male 

 and a female.
