378 Mr. E. E. Austen on Specimens of the Genus 



Wleii. ent. Z., vi. Jahrg., 1887, pp. 5, 11, and 13) (which it 

 would surely be better to call the subfamily Cutiterebkin^) 

 was instituted by Prof. Brauer for Cutiterehra and the allied 

 genera Rogenhofera and Dermatohia. I now find it necessary 

 to introduce a fourth genus, allied to Rogenhofera, for an 

 interesting new species from the 'Mexican shore of the Gulf 

 of California. 



I am aware that, as a result of the recent labours of Brauer 

 and von Bergenstamm, the family ffistridee is abolished, and 

 its constituent genera form a " section " of the Muscidse 

 (" Muscaria Schizometopa," Brauer and v. Berg.) . For the 

 sake of convenience, however, I have decided to retain the old 

 terminology in the title of the present contribution. 



Cutiterehra funebris, sp. n. (PI. XIII. figs. 1-1 h.) 

 Cuter ehra atrox, Clark (?), 'Essay: Addenda' (1848) ; description trans- 

 lated by Brauer, ' Monograpliie der Oestriden,' pp. i^41-242 (18G3). 



The type of this species is a male specimen from Trinidad, 

 forwarded for identification by Mr. J. H. Hart, of the Trinidad 

 Botanical Department. The larva is known in the island as 

 the "Mosquito Worm," and the present specimen, which is 

 accompanied by its pupa-case, was bred from a spiny rat 

 [Loncheres guianw, Thos.). Mr. Hart's statement on the 

 subject will be found below. This species is apparently 

 closely allied to C. atrox, Clk., with which after all it may 

 jn-ove to be identical. Unfortunately, owing to tlie fact that 

 the typical specimen was sent home in a mixture of spirit and 

 glycerine, many of the characters, such as pollinose markings, 

 have been destroyed, while, on the other hand, in spite of 

 many attempts, 1 have not succeeded in obtaining access to 

 Clark's original description of C. atrox, which is accom- 

 panied by a figure : 1 have therefore been forced to content 

 myself with Brauer's translation. On the whole, however, it 

 seemed better to describe the present specimen as new, espe- 

 cially as the type of Clark's species was obtained from 

 Mexico. Since writing the appended description I have 

 discovered that the type of C. atrox is in the Oxford Museum, 

 and by the kindness of Prof. Poulton I hope before long to 

 have an opportunity of comparing it. 



^. Dimensions agreeing very well with those given by 

 Brauer for G. atrox, taken from Clark's figure : length 

 24 millim. (25 millim., Brauer) ; length of wing 20 millim. 

 (as in Brauer); width of vertex 4 millim.; width of head 

 9^ millim. ; width of thorax at base ot wings 9| millim. ; 

 width of abdomen at base of third segment 11 1 millim.
