Maceoteleia, Westwood. 



From rearings of a species in America we now know that tHs 

 genus is parasitic on the eggs of the orthopterous genus Orchi- 

 limum, although it may also prove to infest the eggs of other 

 Locustidse. 



The species from St, Yincent may be thus tabulated : — 



Mesonotal furrows complete. 



Species not entirely black 2. 



Species entirely black, punctate- 

 Abdomen very long, 3| times as long as the 

 head and thorax united ; middle lobe of 

 mesonotum with a median carina ; legs 

 and antennae, except the club, brownish 



yellow or yellow. $ M. carinata, sp. n. 



Abdomen only about 2\ times as long as 

 the head and thorax united; middle 

 lobe of mesonotum not carinate ; legs 

 and antennae, except club, brownish 



yellow or honey-yellow M. Sancti-Vincenti,s^. n, 



2. Abdomen, except sometimes the tip, rufous ; 

 scape and legs brownish yellow ; scutellum 

 with a delicate median carina M. erytJirog aster, sp. n. 



Maceoteleia caeinata, sp. n. 



$ . Length 5"1 millim. Black, punctate ; head quadrate ; 

 antennse brownish yellow or pale rufous, the club black. Pedicel 

 and first funicle-joint lengthened, the latter the longer ; second 

 funicle-joint scarcely half the length of the first ; third very 

 slightly shorter ; fourth transverse- quadrate. Thorax with two 

 furrows, the middle lobe with a central carina. Legs, including 

 coxae, pale rufous or brownish yellow. "Wings subfuscous, the 

 marginal vein once and a half as long as the stigmal, the latter 

 oblique, knobbed; basal nervure wanting. Abdomen very long and 

 pointed, 3g times as long as the head and thorax together, punc- 

 tate and faintly aciculated, the first and second segments striate ; 

 segments 1, 2, and 3 with dorsal longitudinal carinas towards the 

 sides ; the first segment is about half the length of the second, 

 the following being about equal in length. 



Sah. St. Yincent. 



Described from a single specimen. The carinae on the middle 

 mesonotal lobe and the basal abdominal segments are unique in 

 the genus, and readily distinguish the species.
