1. TENTACULATA, Deg. | 2. LITOREA, Fall. 



Only two British species have been recorded of this singular genus, which may 

 at once be distinguished from all the other Anthomyds by the singular spatulate en- 

 largement of the ends of their palpi. Neither of them are common ; L. litorea is 

 a maritime insect. 



24. CAEICEA, Desv. 



Gen. ch. — Eyes bare, widely separated by a space of nearly equal 

 width ill both sexes ; arista with long hairs ; alulets well developed ; 

 tibiae all armed at their apices with four or five spines ; anal vein 

 rather short, only reaching about half-way from the base to the margin 

 the wincr.

C. TIGRINA, Fab. 

 This Tcry common species has a long arista, which is only plumose along its 

 basal half; the distal part being nearly bare. It has only three bristles seated on 

 black spots, behind the transverse suture, in each of the two middle longitudinal 

 rows of setse on the thorax. The females closely resemble those of Spilogaster 

 commnnis, but may be at once distinguished from them by the circlets of spines at 

 the ends of the tibiae. 



C. CILIATO-COSTA, Zett. 

 This differs from C. tigrina by having the two basal joints of the antennae rufous ; 

 by the arista being plumose along almost its whole length ; by having four instead 

 of three bristles behind the suture in the middle dorsal thoracic rows of setae; by 

 the costal spine and cilise being much more developed ; and by the transverse veins 

 of the wings being more clouded. Rare. I only know the male. 



25. MACHOECHIS, Eond. 



Ccenosia, Meig., Sehiii., &c. 

 Gen. ch. — Eyes bare, widely separated in both sexes ; arista pu- 

 bescent ; abdomen of male narrow and sub-cylindrical, with prominent 

 sub-anal appendages ; alulets with unequal-sized scales ; anal veins 

 of wings not prolonged to the margin ; legs elongated. 



1. INTERMEDIA, Fall. j 2. MEDITATA, Fall. 



3. MEANS, Meig. 



M. INTERMEDIA, Fall. 



This, the largest species (5 to 7 mm.), is of a dull ash-grey colour ; the arista is 

 sub-plumose; the thorax is marked witli two brown lines; the abdomen is long, 

 narrow, cylindrical, and immaculate ; the legs are yellow, with the exception of the 

 fore femora, the coxae, and tlie tarsi, which are all grey ; the hind femora are longer 

 than tlic abdomen ; the pulvilli are larm' and yellow. Not uncommon.
